CESG Fishbowl Seminar: Positioning in V2V Communications

November 30, 2012 @ 10:00 am - 11:00 am

Fishbowl (rm. 333 WERC)

Dr. Sushanta Das (NIIT University, Rajasthan)


In order to ensure a secured operation of the V2V system, each vehicle must be able to evaluate its surrounding independently and accurately. For independent and local evaluation, a vehicle may rely on the estimation and verification of different physical parameters like position, time of event etc. Real time localization and positioning of a target with respect to a moving vehicle is a promising technology for realizing the vision of creating numerous location-aware applications in the context of next generation vehicular communications. We propose a novel positioning methodology in which a single moving observer vehicle can estimate the position of a target vehicle without requiring any fixed road-side infrastructure units (RSU) as reference nodes. The proposed method exploits the periodic retransmission of beacons as per the Dedicated Short Range Communication (DSRC) protocol that covers wireless communications for Vehicle-to-Vehicle (V2V) driver-assistance applications.

Bio: Dr. Sushanta Das has worked in the Vehicular Communications and Information Management group at General Motors India Science Laboratory in Bangalore India. Prior to GM, he worked at Philips Research North America as a senior member of research and at Lawrence Berkeley National Laboratory as a visiting researcher. The central component of his research has been in the area of Wireless Communications pertaining to efficient trans-receiver design, broadband communications, multiple antennas (MIMO) and spatial diversity systems, cooperative communications & sensor network. At Lawrence Berkeley Lab, he worked on developing efficient algorithm for energy management in buildings and analyses of daylight discomfort glare. At present, he is working as an Associate Professor at NIIT University in Rajasthan, India, His recent research interests are in the area of V2V (vehicle to vehicle) and V2I (vehicle to infrastructure) communications as part of intelligent driving and smart transportation system.
