Sumit Roy (U. Washington, Seattle, USA)
Sumit Roy (Fellow, IEEE 2007) received the B. Tech. degree from the Indian Institute of Technology (Kanpur) in 1983, and the M. S. and Ph. D. degrees from the University of California (Santa Barbara), all in Electrical & Comp. Engineering in 1985 and 1988 respectively, as well as an M. A. in Statistics and Applied Probability in 1988. His previous academic appointments were at the Moore School of Electrical Engineering, University of Pennsylvania, and at the University of Texas, San Antonio; presently he is Integrated Systems Professor of Electrical Engineering, Univ. of Washington, Seattle where his research interests include analysis/design of communication systems/networks, with a diverse emphasis on various technologies: wireless LANs (802.11) and emerging 5G/beyond 5G standards, multi-standard wireless inter-networking/coexistence and cognitive radio platforms, vehicular and aerial networks, and sensor networking. He was elevated to IEEE Fellow by Communications Society for his “contributions to multi-user communications theory and cross-layer design of wireless networking standards”. He spent 2001-03 at Intel Wireless Technology Lab as a Senior Researcher engaged in research and standards development for ultra-wideband systems (Wireless PANs) and next generation high-speed wireless LANs. He served as Science Foundation of Ireland Isaac Walton Fellow during a sabbatical at University College, Dublin (Jan-Jun 2008) and was the recipient of a Royal Acad. Engineering (UK) Distinguished Visiting Fellowship during summer 2011. During 2014-15, he spent a sabbatical year at Microsoft Research, Bangalore, India, as Erskine Fellow at University of Canterbury, New Zealand and as Short Term Visiting Foreign Expert at Shanghai JiaoTung University. He has published over 100 archival journal and 120 conference publications and his research has been consistently funded by various US agencies and industrial organizations leading to 10 awarded US patents. His activities for IEEE Communications Society includes membership of several technical (notably Technical Comm. on Cognitive Networks) and conference program committees (most recently as TPC co-chair for COMSNeTs). He has served as Associate Editor for all the major ComSoc publications in his area at various times, including the IEEE Trans. Communications, IEEE Trans. on Wireless Communications, IEEE Trans. Mobile Computing and IEEE Trans. Circuits & Systems-II Express Briefs. In 2014, he served as co Guest Editor for July 2014 JSAC Special Issue on Smart Grid Communications and as ComSoc Distinguished Lecturer 2013-2015. His other notable professional activities include reviewing proposals for various international research panels (Singapore, HongKong, Qatar, Greece, Portugal etc.) and serving as external examiner for Ph.D. thesis (Singapore, Australia, Israel, Canada etc.).
Title: “Overview of Radar Sensor Networking Research”
Short abstract: An emerging use case of great interest for 5G/future access networks involves vehicular networking scenarios – whereby terrestrial and aerial nodes are equipped with various sensors (notably cameras and radars/lidars) and transceivers that enable integration of such connected vehicles to the global Internet. This talk will present an overview of some ongoing related research at U. Washington FuNLaB based on a radar sensor testbed using the Texas Instrument (TI) mmWave automotive chirp (linearly frequency modulated) radar evaluation module. An initial summary of the TI FMCW radar board capabilities will be provided.
Radar Object Detection/Recognition: The TI board allows (post de-chirping) initial extraction of 4D feature set for potential objects (range, velocity, angle and temporal location) as the basis for further (higher level) processing. A large radar image dataset has been collected to test and promote fundamental advances in radar based object detection, recognition and classification; the talk will describe some current results.
Multi FMCW Radar Networks: With the increasing proliferation of FMCW radars on vehicles, multi-access interference between vehicular radars is an important future problem in need of innovative solutions. A summary of the impact of multi- FMCW radar interference will provide insights into potential PHY/MAC layer interference mitigation approaches. Specifically, questions such as the capacity for an ideal centralized MAC protocol that schedules radar transmissions on time-frequency resources will be formulated and initial results summarized.
