Feasibility Evaluation of VANET using Directional-Location Aided Routing (D-LAR) Protocol

Vehicular Ad hoc Networks (VANETs) allow vehicles to form a self-organized network without any fixed infrastructure. VANETs have received wide attention and numerous research issues have been identified in the recent time. The design and implementation of efficient and scalable routing protocols for VANETs is a challenging task due to high dynamics and mobility constraints. In this paper, we have proposed D-LAR (Directional-Location Aided Routing), is an extension of Location Aided Routing (LAR) with Directional Routing (DIR) capability. D-LAR is a greedy approach based-position based routing protocol to forward packet to the node present in request zone within the transmission range of the source node as most suitable next-hop node. We have justified the feasibility of our proposed protocol for VANET.
