Research on Energy-Aware Routing Protocol Based on Min Cost Max Flow Algorithm for Mobile Ad Hoc Networks

MANET is currently a hotspot in the wireless networks researching domain, and the routing protocol, which is as the core technology on network layers, is particularly important. Controlling node energy and increasing network lifetime are two keys to realize the transmission of efficient service for MANET. On the basis of analyzing classical MANET routing protocol, and combining with the idea of min cost max flow in networks, this paper puts forward a routing optimization model based on energy control. First, this paper sets up a first-order energy consumption model to analyze the changes of node energy in the network. Then, it sets up the max residual energy shortest path model with regarding distance between nodes as network cost and node residual energy as network traffic. Finally it defines network lifetime as evaluating indicator to do network simulations. Results of simulations show that this model can prolong network lifetime efficiently.
