Executive Summary

IEEE 802.11p/DSRC is a wireless communication protocol designed for vehicular ad hoc networks in order to support safety and commercial non-safety applications. The conventional 802.11 protocols are not suitable for these types of networks because of high vehicular mobility, faster topological changes, and requirements of high reliability and low latency for safety applications. In this paper, the authors present a detailed simulation study of the performance of both DSRC and 802.11 over vehicular networks. They consider two different models of DSRC - preemptive and non-preemptive. They also measure the reliability metrics both in network and application levels for different mobility scenarios.
