【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.
[Abstract]:In order to effectively utilize the heterogeneity of node energy, reduce network energy consumption and prolong network stability period, A clustering routing algorithm for heterogeneous wireless sensor networks with multi-level energy considering both the residual energy and the distance from the node to the base station is proposed. The residual energy of the cluster head and its communication energy consumption with the base station are considered in order to select the appropriate next-hop routing node. Simulation results show that the proposed algorithm can effectively balance network energy consumption and prolong the network stability period. This routing algorithm is superior to several common sensor network routing algorithms in maintaining the number of nodes surviving, reducing network energy consumption and increasing the throughput of network data transmission. It is shown that when energy and distance are taken into account, better results can be obtained than the single algorithm considering energy or distance.
