摘要
为了能有效地利用节点能量的异构性,降低网络能耗、延长网络稳定周期,提出了一种同时考虑节点剩余能量和节点至基站距离的多级能量异构无线传感器网络的分簇路由算法.在节点簇间综合考虑簇头剩余能量及其与基站的通信能耗,以选择合适的下一跳路由节点.仿真结果表明,该算法可以有效地均衡网络能量消耗,延长网络稳定周期.该路由算法在维持节点存活个数、降低网络能量消耗及增加网络数据传输吞吐量等指标方面优于几种常见传感器网络路由算法,表明在综合考虑能量和距离等因素后能够获得比单一考虑能量或者距离的算法更优的运行结果.
In order to effectively use the heterogeneity of node energy and reduce the network energy consumption and prolong network stable period, a clustering routing algorithm for heterogeneous sensor networks with multi stage energies was proposed, takeing into account the residual energy of nodes and the distance from nodes to the base station synchronously. The residual energy of cluster heads and the energy consumption of communication between the nodes and the base station were considered comprehensively to select the appropriate next-hop route node. Simulation results show that this algorithm can balance net- work energy consumption efficiently and extend network stability period. This routing algorithm has a better performance than some ordinary algorithms in the indexes of maintaining the number of survival nodes, reducing the network energy consumption and increasing the throughput of data transmission of nodes. It indicates that it can get better computational results when the factors of energy and distance are considered comprehensively rather than only considering one factor, energy or distance.
