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 present a geometrical 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. In our study we develop a geometrical framework to address the safety measures of urban transportation networks.
We show that there exist fundamental tradeoffs between communication metrics such as network capacity and transportation metrics such as traffic flow. We propose combining traffic flow theory with communication theory to understand the relations between communication and transportation measures. 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.
