Abstract

Vehicular Ad hoc Network (VANET) is classified as an application of Mobile Ad-hoc Networks (MANETs) that has the potential in improving road safety and providing Intelligent Transportation System (ITS). Along with its benefits, VANET is confronted with a lot of challenges ranging from the high energy consumption, instability issues resulting from high topology change. The major objective of developing a route optimal path algorithm is to minimize the chances of link failure and reduce energy consumption of nodes in the network. In this paper, to achieve this objective a modified route optimal path algorithm where nodes are in cluster form is proposed. In this approach, mobility prediction scheme is used for the network stability and two-tier mechanism is used to minimize the energy consumed through a Location Aided Routing (LAR) protocol. Experimental result using Network simulator 2 (NS-2) illustrates that the proposed technique improved energy consumption of nodes in the networks and result found indicates that proposed technique consumes less energy.
