Performance Analysis of IPv4 and IPv6 in VANET Routing

Internet Protocol version6 (IPv6) is the sixth revision to Internet Protocol. This protocol is going to replace IPv4 totally in future. Apart from serving the increasing demand for IP addresses, it also bundles other features for better health of Internet. It is anticipated that IPv6 will boost up speed and quality of service. With increasing demand to provide network to moving users, it has become absolutely important to analyze deployment of IPv6 in the network of moving vehicles, VANET. VANET is a self-organizing wireless network of running or stationary vehicles intended to support safety or intelligent transportation related information exchange between them. Routing plays an important role to facilitate vehicles communicate effectively. That is why this paper intends to compare performance of IPv6 and IPv4 in VANET routing. Two routing protocols, AODV and GPSR are used here for the purpose of analyzing performance in different scenarios. Two parameters are considered to measure and compare performance of IPv6 and IPv4. First parameter is Packet Delivery Ratio (PDR) and second is End-to-End Delay (E2ED). Network Simulator, NS-2 in amalgamation with broadly accepted VanetMobiSim is used to carry out simulation for the selected study. It is observed here that IPv6 provides better performance to both AODV and GPSR as compared to IPv4.
