An Adaptive Greedy Geographical Routing Protocol for Mobile Multihop Wireless Network

In this chapter, we analyze the performance deficiency of traditional routing protocol based on the actual geographical setting and propose a novel adaptive greedy geographical routing protocol. Through analyzing two factors affecting network mobility—the moving speed and the pause time of nodes—the protocol adjusts the beacon sending cycle and selects the better next hop to achieve the goals of reducing overload and increasing the delivery success ratio. Simulation results show that the protocol can acquire better effects compared to GPSR (greedy perimeter stateless routing).
