Inter-vehicle communications is seen as a promising remedy for a number of road-safety issues (e.g., by sending warnings in case of road accidents, low bridges, ice, or oil on road), environmental issues (to improve the efficiency of road traffic by e.g., traffic light scheduling to help the driver to move in the green phase), as well as supporting the on-board infotainment applications.
Equipped with Wireless Access for Vehicular Environment (WAVE) devices, vehicles can dynamically form a Vehicular Ad hoc NETwork (VANET) utilizing seven 10 MHz channels in the 5.880-5.925 GHz band (as assigned by the U.S. Federal Communications Commission – FCC, and defined in a recently ratified 802.11p standard, now being a part of IEEE 802.11-2012 specification). However, inter-vehicle VANET communications often encounters disruptions due to high mobility of vehicles causing frequent failures of communication links.
This talk will first focus on challenges leading to disruptions of end-to-end VANET communications. In particular, it will define research issues related to stability of end-to-end VANET communications. Apart from presenting the state-of-the-art, the latter part of the talk will highlight the latest proposals in this area, in particular including the multihop path stability techniques recently proposed by the author, i.e.: (1) multipath routing in a scenario of differentiated levels of service availability required by different applications, and (2) multihop anypath communications.
Jacek Rak holds Ph.D. degree in computer science received with distinction from Gdansk University of Technology (GUT), Poland in 2009. He is currently an Assistant Professor at the Department of Computer Communications at GUT.
His main research areas include: routing, design, and analysis of communication networks with special focus on network resilience. He is the author/co-author of over 70 publications, including over 30 publications in journals. Dr. Rak has participated in several important projects related to optimization of reliable communication networks. He has also served as a TPC member of numerous international conferences on communications, e.g., IEEE ICC, IEEE GLOBECOM, DRCN, and journals, including IEEE Trans. on Networking, IEEE Communications Letters, or IEEE Trans. on Multimedia. Recently, he has been the TPC Co-chair of ICUMT 2011&2012, NETWORKS 2010, Publication Chair of BCFIC 2011 & 2012, NETWORKS 2010&2012, Workshops Chair of ITST 2013, and Publicity Chair of DRCN 2013, and General Co-chair of INOC 2015. Between 2012 and 2014, he served as a member of the Editorial Board of Telecommunication Systems (Springer). Dr. Rak is currently the Vice Chair of IFIP TC6 WG 6.10, a senior member of IEEE, Steering Committee Member of NETWORKS and ICUMT conferences, as well as the founder and the General Chair of International Workshop on Reliable Networks Design and Modeling (RNDM)
