Our paper entitled "Sub-6GHz Assisted MAC for Millimeter Wave Vehicular Communications", and authored by B. Coll-Perales, J. Gozalvez and M. Gruteser, has been accepted for publication in IEEE Communications Magazine. The paper is a joint work between UWICORE and WINLAB (Rutgers University).
Abstract: Future connected and automated driving applications can require larger bandwidth and higher data rates than currently supported by sub-6GHz V2X technologies (e.g. DSRC, ITS-G5 or C-V2X). This has triggered the interest in developing mmWave vehicular communications. However, solutions are necessary to solve the challenges resulting from the use of high-frequency bands and the high mobility of vehicles. This paper contributes to this active research area by proposing a sub-6GHz assisted mmWave MAC that decouples the mmWave data and control planes. The proposal offloads mmWave MAC control functions to a sub-6GHz V2X technology. This approach improves the operation of the MAC as the control functions benefit from the longer range, and the broadcast and omnidirectional transmissions of sub-6GHz V2X technologies. This study demonstrates that the proposed sub-6GHz assisted mmWave MAC reduces the control overhead and delay, and increases the spatial sharing compared to mmWave communications using a configuration of IEEE 802.11ad tailored to vehicular networks. The proposed MAC is here evaluated for V2V communications using 802.11p for the control plane and 802.11ad for the data plane, although it can be adapted to other technologies such as C-V2X and 5G NR-V2X.

Our paper entitled "Analytical Models of the Performance of C-V2X Mode 4 Vehicular Communications", and authored by Manuel Gonzalez-Martín, Miguel Sepulcre, Rafael Molina-Masegosa and Javier Gozalvez, has been accepted for publication in IEEE Transactions on Vehicular Technology.
Abstract: The C-V2X or LTE-V standard has been designed to support V2X (Vehicle to Everything) communications. The standard is an evolution of LTE, and it has been published by the 3GPP in Release 14. This new standard introduces the C-V2X or LTE-V Mode 4 that is specifically designed for V2V communications using the PC5 sidelink interface without any cellular infrastructure support. In Mode 4, vehicles autonomously select and manage their radio resources. Mode 4 is highly relevant since V2V safety applications cannot depend on the availability of infrastructure-based cellular coverage. This paper presents the first analytical models of the communication performance of C-V2X or LTE-V Mode 4. In particular, the paper presents analytical models for the average PDR (Packet Delivery Ratio) as a function of the distance between transmitter and receiver, and for the four different types of transmission errors that can be encountered in C-V2X Mode 4. The models are validated for a wide range of transmission parameters and traffic densities. To this aim, this study compares the results obtained with the analytical models to those obtained with a C-V2X Mode 4 simulator implemented over Veins.
Baldomero Coll-Perales, a research fellow at UWICORE, will spend four months at the Institute of Informatics and Telematics of CNR (Consiglio Nazionale delle Ricerche - National Research Council), Pisa, Italy (https://www.iit.cnr.it/en). Baldomero will work with Dr. Andrea Passarella and Dr. Loreto Pescosolido. During the postdoctoral stay, Baldomero will work on the design of demand-driven opportunistic networking schemes. Demand-driven opportunistic networking is aimed at extending the concept of opportunistic networking to situations where connections between devices and nodes (other devices or the base station) are established not just based on their presence, but also on their capacity to support the requested demand and services. The concept of demand-driven opportunistic networking can be tailored to any user, service or network demand such as latency, reliability, data rate, energy-efficiency or spectrum-efficiency to name a few. These research activities are driven by the belief that devices (whether mobile phones/devices or vehicles) should have a more active role in network management and operation, as their communications, computing, processing and sensing capabilities are currently under-utilized, but they will play a major role in the design of future wireless networks.

Our paper entitled "Context-Aware Heterogeneous V2X Communications for Connected Vehicles", and authored by Miguel Sepulcre and Javier Gozalvez, has been accepted for publication in Computer Networks.
Abstract: Connected vehicles will require heterogeneous or hybrid communication technologies to implement the full range of cooperative ITS services in diverse scenarios. This paper presents an architecture for context-aware heterogeneous vehicular networks. The architecture is compatible with the current ETSI and ISO standardized ITS station reference architectures, and allows for the dynamic selection and configuration of communication profiles based on the context conditions and the application requirements. The potential of the proposed architecture is demonstrated with the implementation and evaluation of a heterogeneous V2I communications algorithm that improves the quality of service and the capacity to satisfy the vehicular application requirements, and reduces the economic cost of connected vehicle services.

Our paper entitled "Distributed Radio Resource Allocation for Device-to-Device Communications Underlaying Cellular Networks", and authored by M.C. Lucas-Estañ, J. Gozalvez, has been accepted for publication in Journal of Network and Computer Applications.
Abstract: Underlaying Device-to-Device (D2D) communications can increase the spectral efficiency of cellular networks when sharing part of the spectrum with cellular users. This requires radio resource allocation policies capable to limit and control the interference between D2D and cellular communications. Many of the proposed policies are centralized, and require the base station to decide which resources should be allocated to each D2D transmission. Centralized schemes can efficiently control interference levels, but their feasibility can be compromised by their complexity and signaling overhead. To address this constraint, this paper proposes DiRAT, a distributed radio resource allocation scheme for D2D communications underlaying cellular networks. With DiRAT, the D2D nodes locally select their radio resources from a pool created by the cellular network in order to control the interference generated to the primary cellular users. DiRAT includes a control mechanism to ensure that the user QoS requirements are satisfied. This study demonstrates that DiRAT can increase the network capacity while avoiding or limiting the degradation of the performance of the primary cellular users. DiRAT also significantly reduces the complexity and overhead compared to existing centralized and distributed schemes.

Our paper entitled "Why 6Mbps is not (always) the Optimum Data Rate for Beaconing in Vehicular Networks", and authored by Miguel Sepulcre, Javier Gozalvez and Baldomero Coll-Perales, has been accepted for publication in IEEE Transactions on Mobile Computing.
Abstract: The IEEE 802.11p standard has been created for vehicle to vehicle and vehicle to infrastructure communications. Vehicular networks require vehicles to periodically broadcast beacons in order to detect nearby vehicles or road infrastructure nodes and exchange critical information. The IEEE 802.11p standard defines different data rates that can be used for such transmissions, but 6Mbps has been generally assumed as the default data rate. Limited efforts have been conducted to date to demonstrate whether 6Mbps is the optimum data rate or not. This study addresses this issue, and demonstrates by means of simulations and field experiments that 6Mbps is not (always) the optimum data rate for beaconing in vehicular networks. The conclusions are validated in both urban and highway environments.

Our paper entitled "Link Scheduling Scheme with Shared Links and Virtual Tokens for Industrial Wireless Sensor Networks", and authored by Sergio Montero, Javier Gozalvez and Miguel Sepulcre, has been accepted for publication in Mobile Networks and Applications.
Abstract: Industrial wireless sensor networks can help improve the efficiency, reconfigurability and flexibility of future factories, and facilitate the introduction of new applications. Industrial applications are generally characterized with strict reliability and latency requirements. The capacity to meet such requirements is highly dependent on an efficient utilization of communication links. Such efficient utilization will become even more critical as the number of deployed sensors and traffic in factories increase. In this context, this paper presents a novel link scheduling scheme for industrial wireless sensor networks that uses shared links among nodes that are part of the same path or multi-hop route. The transmission of a message along a route acts as a virtual token to identify which node should use the shared links at each point in time. This study demonstrates that the proposed link scheduling scheme can significantly improve the reliability, latency and efficiency of industrial wireless sensor networks. The proposed link scheduling scheme is here applied to industrial wireless sensor networks, but it can be used in other centralized TDMA-based multi-hop wireless networks.

Our paper entitled "On the Capacity Gain of Multi-Hop Cellular Networks with Opportunistic Networking and D2D: a Space-Time Graph-based Evaluation", and authored by Baldomero Coll-Perales and Javier Gozalvez, has been accepted for publication in IEEE Wireless Communications Letters.
Abstract: Previous studies have shown that device-centric wireless technologies, including multi-hop cellular networks (MCNs) and device-to-device (D2D) communications, can increase the cellular network capacity. This study progresses the current state of the art by deriving (using space-time graphs) the upperbound capacity gains that can be further achieved when integrating efficiency-driven opportunistic networking into device-centric wireless networks. The increase is obtained without modifying the radio interface, and is not constrained to any particular radio interface.

Our paper entitled "LTE-V for Sidelink 5G V2X Vehicular Communications: A New 5G Technology for Short-Range Vehicle-toEverything Communications", and authored by Rafael Molina-Masegosa and Javier Gozalvez, has been accepted for publication in IEEE Vehicular Technology Magazine.
Abstract: This paper provides an overview of the LTE-V standard supporting sidelink or V2V communications using the PC5 interface in LTE. The paper reviews the physical layer changes introduced under Release 14 for LTE-V, its communication modes 3 and 4, and the LTE-V evolutions under discussion in Release 15 to support 5G V2X communications and autonomous vehicles' applications. Modes 3 and 4 support direct V2V communications, but differ on how they allocate the radio resources. Resources are allocated by the cellular network under Mode 3. Mode 4 does not require cellular coverage, and vehicles autonomously select their radio resources using a distributed scheduling scheme supported by congestion control mechanisms. Mode 4 is considered the baseline mode, and represents an alternative to 802.11p or DSRC. In this context, the paper also presents a detailed analysis of the performance of LTE-V sidelink Mode 4, and proposes a modification to its distributed scheduling.
Our paper entitled "Neighbor Discovery for Industrial Wireless Sensor Networks with Mobile Nodes", and authored by Sergio Montero, Javier Gozalvez and Miguel Sepulcre, has been accepted for publication in Computer Communications.
Abstract: Industrial wireless sensor networks can facilitate the deployment of a wide range of novel industrial applications, including mobile applications that connect mobile robots, vehicles, goods and workers to industrial networks. Current industrial wireless sensor standards have been mainly designed for static deployments, and their performance significantly degrades when introducing mobile devices. One of the major reasons for such degradation is the neighbor discovery process. This paper presents and evaluates two novel neighbor discovery protocols that improve the capability of mobile devices to remain connected to the industrial wireless sensor networks as they move. The proposed protocols exploit topology information and the nature of devices (static or mobile) to reliably and rapidly discover neighbor devices. This is achieved in some cases at the expense of increasing the number of radio resources utilized and the energy consumed in the discovery process. The proposed solutions have been designed and evaluated considering the WirelessHART standard given its widespread industrial adoption. However, they can also be adapted for the ISA100.11a and IEEE 802.15.4e standards.

Our paper entitled "Multipath QoS-Driven Routing Protocol for Industrial Wireless Networks", and authored by Miguel Sepulcre, Javier Gozalvez and Baldomero Coll-Perales, has been accepted for publication in Journal of Network and Computer Applications.
Abstract: The Industry 4.0 concept targets the interconnection and computerization of traditional industries to improve their adaptability and utilize efficiently their resources. Industrial wireless networks will play a key role within the Industry 4.0 as they will facilitate the deployment of novel industrial applications thanks to the flexible and reconfigurable wireless connection of industrial devices. Significant advances are still necessary to enable the deployment of reliable industrial wireless networks capable to guarantee the strict QoS (Quality of Service) requirements of industrial applications in harsh propagation conditions. This paper contributes towards this objective with a novel multipath routing protocol that identifies and establishes the necessary redundant routes between any pair of nodes of a wireless network in order to satisfy the reliability and delay QoS levels demanded by industrial applications. The proposed protocol is here presented and analyzed under the framework of the WirelessHART standard given its important industrial adoption. However, it can also be adapted to other centralized TDMA-based multi-hop wireless networks.

Paper accepted in Springer's Telecommunication Systems
Our paper entitled "Contextual optimization of location-based routing protocols for multi-hop cellular networks using mobile relays", and authored by Baldomero Coll-Perales and Javier Gozalvez, has been accepted for publication in Springer's Telecommunication Systems.
Abstract: Traditional single-hop cellular architectures fail to provide high and homogeneous quality of service levels throughout a cell area due to the strong signal attenuation with the distance. In this context, multi-hop cellular networks that utilize mobile relays and device-to-device communications have been proposed to overcome the physical limitations of conventional cellular architectures. One of the key building blocks of multi-hop cellular networks is the multi-hop routing of information from the source to the destination. This paper investigates the performance and energy signaling benefits of location-based multi-hop routing protocols. In particular, the paper demonstrates the benefits of a contextual optimization of this type of protocols in order to achieve a high end-to-end performance, while reducing the energy and signaling implementation cost.

Our paper entitled "Energy-efficient opportunistic forwarding in multi-hop cellular networks using device to device communications", and authored by B. Coll-Perales, J. Gozalvez and V. Friderikos, has been accepted for publication in Transactions on Emerging Telecommunications Technologies. The paper is a joint work between UWICORE and Centre for Telecommunications Research, King's College London.
Abstract: Cellular networks face significant challenges as a result of the growth of cellular data traffic, with a significant portion of such traffic being delay tolerant. Multi-hop Cellular Networks (MCN) can help address the foreseen capacity and energy-efficiency constraints of cellular networks through the integration of cellular and Device to Device (D2D) communications. To this aim, this work proposes and studies the use of opportunistic store, carry and forward mechanisms in MCN networks to increase energy efficiency for delay tolerant traffic. In particular, the study first derives an analytical framework to identify in two hop scenarios the optimum mobile relay location and the location from which the mobile relay should start forwarding the information to the cellular base station in order to minimize the overall energy consumption. The derived optimum configuration is then used as a benchmark for the development of a context-based opportunistic MCN forwarding scheme that exploits context information provided by the cellular network. Numerical and simulation results demonstrate that significant energy benefits (above 90%) can be achieved through the use of opportunistic forwarding in MCN networks.
Our paper entitled "Integration of Congestion and Awareness Control in Vehicular Networks", and authored by Miguel Sepulcre, Javier Gozalvez, Onur Altintas and Haris Kremo, has been accepted for publication in Ad Hoc Networks. The paper is a joint work between UWICORE and TOYOTA.
Abstract: Cooperative vehicular networks require the exchange of positioning and basic status information between neighboring nodes to support vehicular applications. The exchange of information is based on the periodic transmission/reception of 1-hop broadcast messages on the so called control channel. The dynamic adaptation of the transmission parameters when broadcasting such messages will be key for the reliable and efficient operation of vehicular networks. To this aim, vehicular networks utilize congestion control protocols to control the channel load, typically through the adaptation of the transmission parameters based on certain channel load metrics. Awareness control protocols are also required to adequately support cooperative vehicular applications. These protocols typically adapt the transmission parameters of periodic broadcast messages to ensure each vehicle's capacity to detect, and possibly communicate, with the relevant vehicles and infrastructure nodes present in its local neighborhood. To date, congestion and awareness control protocols have been normally designed and evaluated separately, although both will be required for the reliable and efficient operation of vehicular networks. In this context, this paper proposes and evaluates INTERN, a new control protocol that integrates two congestion and awareness control processes. The simulation results obtained for three different scenarios demonstrate that INTERN is able to satisfy the applications' requirements of all vehicles, while effectively controlling the channel load. The results obtained highlight the challenges ahead with emerging automated vehicles.
Our paper entitled "Context-Aware Opportunistic Networking in MultiHop Cellular Networks", and authored by B. Coll-Perales, J. Gozalvez and V. Friderikos, has been accepted for publication in Ad Hoc Networks. The paper is a joint work between UWICORE and Centre for Telecommunications Research, King's College London.
Abstract: 5G networks will be required to efficiently support the growth in mobile data traffic. One approach to do so is by exploiting Device-to-Device (D2D) communications and Multi-Hop Cellular Networks (MCNs) in order to enhance the spectrum re-use and offload traffic over underlay networks. This study proposes to further improve the efficiency of transmitting mobile data traffic by integrating opportunistic networking principles into MCNs. Opportunistic networking can exploit the delay tolerance characteristic of relevant data traffic services in order to search for the most efficient transmission conditions in MCNs. The study first presents an analytical framework for two-hop opportunistic MCNs designed to identify their optimum configuration in terms of energy efficiency. Using this reference configuration, the paper then proposes a set of opportunistic forwarding policies that exploit context information provided by the cellular network. Numerical and simulation results demonstrate that opportunistic networking can significantly contribute towards achieving the capacity and energy efficiency gains sought for 5G networks. Under the evaluated conditions, the obtained results show that the proposed schemes can reduce the energy consumption compared to traditional cellular communications by up to 98% for delay tolerant services. In addition, the proposed schemes can increase the cellular capacity by up to 79% compared to traditional cellular communications.

Our paper entitled "Empirical Models of the Communications Performance of Multi-hop Cellular Networks using D2D", and authored by B. Coll-Perales, J. Gozalvez and M. Sepulcre, has been accepted for publication in Journal of Networks and Computer Applications.
Abstract: Multi-hop Cellular Networks (MCNs) can improve the quality of service, capacity and energy-efficiency of traditional infrastructure-centric single-hop cellular systems. MCN systems can exploit Device-to-Device (D2D) communications and utilize the communications and computing capabilities of mobile devices. However, the communications challenges resulting from the use of mobile devices and D2D communications require empirical solid evidences of their performance benefits, and the design of robust communications and networking protocols. In this context, this paper presents a unique set of empirical models of the communications performance of MCN systems that utilize D2D communications. The models take into account the impact of the distance, propagation/visibility conditions, number of hops, and communication settings. The set of derived models can help design, test and optimize communications and networking protocols for MCNs that utilize D2D communications.

Paper accepted in Computers in Industry
Our paper entitled "On the feasibility to deploy mobile industrial applications using wireless communications", and authored by Javier Gozalvez, Miguel Sepulcre and Jose Antonio Palazon, has been accepted for publication in Computers in Industry.
Abstract: Wireless communications can facilitate the deployment of novel industrial applications to improve productivity or health and safety conditions. Health and safety applications require mobile solutions capable to operate under harsh propagation conditions at low cost and energy consumption. This paper presents the results of an extensive measurement campaign that demonstrate the feasibility to deploy industrial mobile sensing applications with reliable wireless connectivity levels using short-range IEEE 802.15.4. The campaign also analyses the capability of various wireless technologies to provide the throughput levels necessary for wireless local data distribution and backhaul connectivity.
Our paper entitled "Reputation based selfishness prevention techniques for mobile ad-hoc networks", and authored by Alberto Rodríguez-Mayol and Javier Gozalvez, has been accepted for publication in Telecommunication Systems.
Abstract: Mobile ad-hoc networks require nodes to cooperate in the relaying of data from source to destination. However, due to their limited resources, selfish nodes may be unwilling to forward packets, which can deteriorate the multi-hop connectivity. Different reputation-based protocols have been proposed to cope with selfishness in mobile ad-hoc networks. These protocols utilize the watchdog detection mechanism to observe the correct relaying of packets, and to compile information about potential selfish nodes. This information is used to prevent the participation of selfish nodes in the establishment of multi-hop routes. Despite its wide use, watchdog tends to overestimate the selfish behavior of nodes due to the effects of radio transmission errors or packet collisions that can be mistaken for intentional packet drops. As a result, the availability of valid multi-hop routes is reduced, and the overall performance deteriorates. This paper proposes and evaluates three detection techniques that improve the ability of selfishness prevention protocols to detect selfish nodes and to increase the number of valid routes.

Abstract: The FASyS (Absolutely Safe and Healthy Factory) project, aligned with the European Factories of the Future (FoF) concept, has been set-up to develop a new factory model aimed at minimizing the risks to the worker's health and safety, and guarantee their welfare and comfort in machining, handling and assembly factories. To this aim, ICT Information and Communication Technologies) and wireless communication technologies in particular may represent very valuable tools to implement distributed and mobile sensing applications capable to continuously sense the working environment and the worker's health and safety conditions. The effective deployment of such applications in critical environments, like the industrial one, require the availability of a platform capable to monitor the operation and performance of the heterogeneous wireless networks that will connect the mobile sensors to remote control centres. This paper presents the platform implemented for this purpose in the context of the FASyS project. In addition to monitoring the status of heterogeneous wireless networks, the implemented platform provides the capability to reconfigure remotely the communication settings of wireless nodes based on possible malfunctioning or QoS degradation notifications. These functionalities will help guaranteeing the reliable and robust wireless communications required in industrial environments to implement innovative labour risk prevention applications exploiting ICT technologies.

Uwicore paper selected among the top 5 papers at the IEEE International Symposium on Wireless Vehicular Communications (WiVeC)
8th January 2008
Uwicore's paper "Opportunistic-Driven Adaptive Radio Resource Management Technique for Efficient Wireless Vehicular Communications", authored by Javier Gozalvez and Miguel Sepulcre, has been selected among the top 5 papers at the IEEE International Symposium on Wireless Vehicular Communications (WiVeC) that took place from the 30th September to the 1st October 2007 in Baltimore (USA). The paper presents Uwicore's OPRAM proposal to adaptively modify the transmission parameters (e.g., transmission power and/or rate) in wireless vehicular communications systems based on the potential presence of a road danger. The proposed mechanism is able to guarantee the established QoS thresholds (in this case, guaranteeing a driver is informed of a potential driving danger with sufficient time to react) while efficiently using the radio resources and minimizing channel congestion. Although the proposal initially considers Vehicle to Vehicle (V2V) communications and traffic safety applications, it could easily be extended for Vehicle to Infrastructure (V2I) communications and other applications like traffic efficiency or Internet on the move. The best 5 papers of the conference will now be published in a special issue of the IEEE Vehicular Technology Magazine. The other 4 selected papers are:
Experimental Analysis of Dense Vehicular Networks: An ORBIT Testbed Case Study, Kishore Ramachandran and Marco Gruteser, WINLAB, Rutgers University, USA.
V2V Channels and Performance of Multi-user Spread Spectrum Modulation, Indranil Sen and David W. Matolak, Ohio University, USA
Non-Isotropic Fading Channel Model for the Highway Environment, Jared Dulmage and Michael P. Fitz, University of California, Los Angeles, USA
Six Time- and Frequency-Selective Empirical Channel Models for Vehicular Wireless LANs, Guillermo Acosta-Marum and Mary Ann Ingram, Georgia Institute of Technology, USA
For a second consecutive year, a Uwicore member receives the France Telecom Foundation Award at the main Young Scientist contest in Spain
5th December 2007
Uwicore's Mari Carmen Lucas Estañ has received the France Telecom Foundation Award at the main Young Scientist contest in Spain, the VI Certamen Universitario "Arquímedes" de Introducción a la Investigación Científica. The contest has been created by the Spanish Ministry of Education and Science to distinguish university students that are developing original ideas that will contribute to the development of research activities in Spanish universities. Mari Carmen's work was initially selected among the best 25 to participate in the final phase at the University of Alcalá, where she was then awarded the France Telecom Foundation award. In her work, Mari Carmen has been studying the use of bankruptcy policies for radio resource management in mobile and wireless systems with heterogeneous multimedia traffic. The use of bankruptcy policies was considered because of their use in situations where the value of a company is inferior to its debts and therefore a sharing scheme needs to be put in place. This is exactly the situation that can be foreseen as mobile and wireless traffic and bandwidth increases with the introduction of multimedia applications. Prior to Mari Carmen's success, Uwicore's alumni Miguel López Benítez was awarded the France Telecom Foundation award at the 2006 Arquimedes contest for his research activities on beyond 3G or 4G common radio resource management schemes for heterogeneous wireless networks.
