Vehicular Ad hoc Networks (VANET) is a highly dynamic field due to the fast movement of vehicles acting as nodes. Designing a routing protocol capable of dealing with multiple limiting conditions such as long congestion periods, link failures and handoffs is a challenging task, where most of the existing multipath routing protocol shows poor performance. In this paper, a Multipath Route Restoration Protocol (MRRP) is proposed that focuses not just on route change in case of link failure due to congestion, but also on the route restoration of the link failure path from source to destination. The proposed protocol is implemented on a lattice topology in an urban scenario using Network Simulator-2(NS-2). Simulation results show that compared to the existing protocols, the throughput and average end-to-end delay is better in our proposed work.
