Title:
Vehicular communications: a way to improve driving safety, highway efficiency, and driver convenience
Speaker:
Dr. Hossein Pishro-Nik
Assistant Professor
ECE Dept., UMass, Amherst
Abstract:
Every year, more than 40,000 people are killed and 3 million people are injured in highway traffic accidents in the United States alone. Traffic accidents lead by a wide margin any other cause of death in the 15 to 34 age group. Moreover, traffic congestion wastes 40 percent of travel time, unnecessarily consumes about 2.3 billion gallons of fuel per year, and adversely impacts the environment. Many countries are planning the deployment of large scale vehicular ad hoc networks (VANETs) due to the potentially dramatic improvements in safety, highway efficiency, and driver convenience.
In this talk, we first give an overview of VANETs. We then provide a mathematical framework for analysis of these networks. In urban areas the geometry of roads and the placement of obstacles play an important role in determining the efficient communication strategy. Here, due to the high penetration loss of the 5.9 GH.z. wave passing through obstacles, single-hop communications between non-Line-of-Sight vehicles is not always the best choice. In our study we develop a geometrical framework to address the safety measures of urban transportation networks. Moreover we propose criteria to indicate how obstacles can degrade the safety measures of a network by hindering the Line-of-Sight of near-by vehicles.
We then present our findings from a real life implementation of a VANET prototype that exploits dedicated short-range communication (DSRC) technology to alert drivers of potential red light runners. The project is tested in a variety of situations to show its effectiveness for different scenarios.
Bio:
Hossein Pishro-Nik is an Assistant Professor of Electrical and Computer Engineering at the University of Massachusetts Amherst. He received a B.S. degree from Sharif University of Technology, and M.Sc. and Ph.D. degrees from Georgia Institute of Technology, all in Electrical and Computer Engineering. Since joining UMass in 2005, Professor Pishro-Nik has built a research program focused on the mathematical analysis of communication systems, in particular, Error Control Coding, Wireless Networks, and Vehicular Ad Hoc Networks. His awards include an NSF Faculty Early Career Development (CAREER) award, an Outstanding Junior Faculty Award from UMass, and an Outstanding Graduate Research Award from Georgia Tech.
