ABSTRACT
At present, Mobile Ad Hoc Networks (MANET) have become a hot research field, in view that the mobile nodes have the characteristics of mobility, limited energy, limited storage space and so on. Thus to design a simple and high-efficiency routing protocol is an important issue. AODV routing protocol can resolve the routing problem of Mobile Ad Hoc Networks, but it still has many shortcomings, such that it uses flooding method to broadcast messages and finds the route, which cause heavy network overhead and other problems. In this paper, in order to resolve the low efficiency of simple flooding, we first analyze AODV routing protocol briefly. After that we propose an improved routing broadcast algorithm--GAODV, which aims to restrict the forwarding nodes within a local area through the geometrical routing, and prevent from flooding the control packet in the whole network. Simulation results show that the G-AODV effectively reduces network overhead and the end to end delay. Moreover, it also significantly improves the effectiveness of protocol and the overall performance of the network.
