A Study and Performance Analysis of DSR Routing Protocol in VANET

Vehicular Ad-hoc Networks (VANETs) is an emerging technology that has been recently attracting an increasing attention from both research and industry communities. VANET is a collection of wireless vehicle nodes forming a temporary network without using any centralized Road Side Unit. VANET is a subset of MANET. Routing is the important component of communication protocols in VANETs. Packets are routed from source node to destination node. Because of frequent topology changes and routing overhead, selection of routing protocol in VANET is a great challenge. There are various routing protocols available for VANET. This paper involves study of Dynamic Source Routing protocol and performance metrics are analyzed with the help of NS2 Simulator.
