EGRP: Enhanced Geographical Routing Protocol for Vehicular Adhoc Networks

Conference paper
Part of the Lecture Notes in Networks and Systems book series (LNNS, volume 5)

Abstract

Vehicular Ad hoc Networks (VANETs) is an advanced wireless ad hoc network to communicate between the vehicular nodes. The unique characteristic of Vehicular Adhoc Networks leads to frequent network fragmentation and route reconstruction which cause an increase in packet drop ratio and control overhead. Thus, it brings challenges to establish an optimized routing path with high reliability and low latency. This paper presents an improved geographical forwarding strategy to select the next hop based on the mobility metrics such as distance, speed and moving direction of the nodes. These routing metrics have an impact on the performance of the routing protocol for Vehicular Ad hoc Networks (VANETs). Extensive simulations carried out based on the proposed solution have proved to outperform the existing GPSR approaches in terms of reliability, scalability and path latency.
