New Multi-level Routing Protocols MLRP of Car MANET

In order to meet the communications needs of car MANET with low latency, high-rate, through the analysis of Numerous classical routing protocol, we propose a new multi-level clustering routing protocol MLRP, this protocol is designed to reduce the effect of moving the nodes and routing protocol for routing discovery process of flooding overhead. Its fast-forwarding mechanism to accelerate the search by the process and its local route repair mechanism limits the extension link bad area, and improve the speed of the network restoration. Simulation results show that in the case of car MANET topology rapidly changing, the protocol can effectively shorten the route addressing times, and reduce the transmission delay while increasing throughput.
