Abstract: Vehicular Ad-hoc network (VANET) is a group of vehicular nodes making a temporary network without the help of any centralized infrastructure or administration. VANETs have no static configuration because of its dynamic feature of nodes. So, efficient and reliable routing is one of the significant issues in VANETs. Hence, so many routing protocols and algorithms have been improved and developed for fulfilling this objective. Thus, it’s very complicated to find which protocol performance is best in various network scenarios. This paper introduce improved Multicast AODV (IMAODV) routing protocol with restricted source routing that confirms providing reliable, on-time and accurate data in V2V communication in comparison of Improved AODV (IAODV). In result analysis, introduced IMAODV protocol performance is compared with AODV, IAODV and MAODV protocol with respect to Average End-to-End Delay (Avg. E-to-E Delay), Packet Delivery Ratio (PDR), Packet Loss Ratio (PLR), and Normalized Routing Load (NRL). Simulation analysis results illustrate that the performance of IMAODV protocol is better as compared to IAODV protocol in VANETs.
