End-to-End Delay Enhancement with Ring Cluster AODV in VANET

The number of cars has been on the increase leading to an increase in the need to have vehicle communication. The emerging Vehicular Ad Hoc Network (VANET) is therefore very important. Network performance is decided using the routing in VANET. Ad Hoc On-Demand Distance Vector (AODV) is an algorithm that is used in the routing process though it causes more delays. This paper proposes the use of a temporary modified AODV (TM-AODV) routing protocol to be used in the elimination of the end to end delay. Sumo and NS2 simulator has been used in making comparisons of the performances of AODV and TM-AODV using IEEE 802.11p and IEEE 802.11g as MAC depending on the number of the cars that are on the road and the varying speeds at which they are moving in both the city and highway scenarios. According to the results, TM-AODV is better in terms of performance compared to AODV when looking at the throughput and end-to-end delay. This paper aims at looking for ways that will improve the performance of AODV through the enhancement of the existing protocol through the creation of stable clusters and performing routing by Gateway nodes and Cluster Heads.
