摘要
根据无线传感器网络节点能量消耗和网络生存周期的特点,通过建立动态规划能量优化模型,在路由总能耗满足能量阈值约束条件下,均衡消耗网络中各节点能量,在此基础上提出一种适合无线传感器网络的动态规划路由算法。仿真结果表明,提出的路由算法能充分地利用有限的能量资源,较大地延长网络生存周期并降低节点的平均能耗。
According to the characteristic of nodes’ energy consuming and network lifetime in the wireless sensor networks, the paper proposed a dynamic programming model for energy-optimizing. Under the constraint of the total energy-consuming, 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.
