Abstract:This paper proposed an opportunistic routing based on energy-constrainting in mobile Ad hoc networks to maximize the life of energy-constrainting wirless networks. Firstly, introduced the node energy-consuming model(NECM), and constructed the waiting time function(WTF). Then proposed the strategy for selecting forwarding candidates set based on metric named ECETX which consider both the unitary energy(PI) and the link state in order to build the delivery matrix, and then selected the nodes’ priorities which in forwarding candidates set. At last, designed an energy-constrainting opportunistic routing(ECOR) based on all of the above strategies. The simulation results show that the life of the network using ECOR is longer than using ExOR, increase by 60~70 percents in average, and the throughput increase by about 15~23 percents. ......
