面向用电信息采集的WSN非均匀分簇多跳路由算法

摘要

To solve the problem of traditional WSN, an uneven clustering multi-hop routing algorithm for power information collection (UCPC) is proposed. The algorithm uses a hierarchical network topology structure, and considers both the influence of the location and the residual energy on cluster heads routing (CHs). Triangle module operator is used to integrate the degree of location-based membership function and that of the residual energy. And parent node is decided by the fusion results. Simulation results show that UCPC effectively balances and reduces the energy consumption, and obviously prolongs the network lifetime. The routing algorithm can achieve good performance when it is applied into the information collection system.%　　针对传统多跳路由协议的“热区”问题，提出一种面向用电信息采集的WSN非均匀分簇多跳路由算法。算法将网络分为虚拟块，并在簇头路由时考虑节点位置和剩余能量的影响，利用三角模融合算子对基于节点位置的隶属度函数和剩余能量隶属度函数进行融合判决，并根据最大隶属度原则选择父节点，优化路由选择。实验结果表明，改进后的算法显著延长了网络生存时间，同时具有更好的负载平衡程度。将该路由算法应用于用电信息采集系统中，能达到较好的性能。
