An Intersection Based Routing Protocol for Vehicular Ad Hoc Networks

Vehicular ad hoc networks (VANETs) allow vehicles to form a self-organized network without the need for permanent infrastructure .As a prerequisite to communication, an efficient route between network nodes must be established, and it must adapt to the rapidly changing topology of vehicles in motion. This is the aim of VANET routing protocols. In this paper we analyse an intersection based routing (GYTAR) approach that makes use of the navigational systems of vehicles. Intersection based routing can eliminate the problem of geographic source routing. By means of simulation we compare this approach with position-based ad hoc routing strategy (geographic Source Routing).Simulation results show significant performance improvement in terms of packet delivery ratio, end-to-end delay, and routing overhead.
