Vehicular Ad hoc NETwork (VANET) is a versatile mobile wireless ad-hoc network targeted to support traffic monitoring, vehicular safety and many more applications. For the robust and reliable services in the VANET there is need for selection of efficient protocol to check the performance under frequent handovers in Mobile IP to prevent packet loss. Mobile IP is an interface that helps to track the mobile nodes and deliver messages even if vehicles are out of the coverage area of home node. In order to find the achievable performance bounds in terms of throughput, packet drop, collision rate and packet broadcast rate, extensive simulations have been done. A realistic city scenario has been proposed here by using the rician channel simulator, mobile IP enabled IEEE 802.11b OBUs and RSUs. The transmission speed levels of vehicles have been varied to obtain the optimum performance through realistic conditions.
