An improved AODV protocol based on extension lifetime of the Ad Hoc networks

AODV routing protocol makes least hops as a principle when establishing routes. Nodes in Ad Hoc networks have limited energy. Node will exit the network and cannot provide service when its energy is depleted. In recent years, many works have been taken to save energy of ad hoc networks. This paper presents a method which can prolong network lifetime. In this paper, we take node load, remaining energy and moving speed into account to establish more stable routing and avoid excessive consumption of every node. This method can save energy and balance the energy consumption of each node. At the end of paper, we use ns-2 to test the performance of the improved protocol and the results of simulation show that the improved AODV routing protocol can prolong Ad Hoc network lifetime.
