Abstract:According to the characteristic of nodes’ energy consuming and network lifetime in the wireless sensor networks, the paper proposed a dynamic programming model for energyoptimizing. Under the constraint of the total energyconsuming, which was less than the energy threshold value, presented a routing algorithm based on dynamic programming model, which made the network nodes’ energy consuming uniformly during routing from source to destination. Simulation results show that the proposed routing algorithm can utilize the limited energy resources rationally, and prolong the network lifetime and decrease the average energy consumption effectively.......
