Abstract

Vehicular Ad Hoc Network (VANET), a subset of Mobile ad hoc networks, primarily focuses on traffic safety but now-a-days much research is focused on integrating VANETs with internet. With infrastructure based VANET communication, even connectivity could be established with internet. Effective communication between two nodes within a VANET or with an infrastructure unit is assisted by routing protocols. Hence routing plays a vital role in data communication. Most of the routing protocols of VANET follow greedy approach. Many greedy routing protocols have been proposed by eminent researchers. The performance of these greedy routing protocols depends on the recovery strategy adopted by them. This paper presents a novel approach of applying cartographic concepts to enhance the performance of greedy protocol by minimizing the hop count of the path in perimeter mode using curve simplification algorithm. The results show significant reduction in the number of hops required to deliver data to the destination when compared with GPSR protocol.
