能量受限和能耗的不均衡性是限制无线传感器网络( WSNs)生命周期的两大主要因素。首先引入了一个新均衡性指数-泰勒指数，其次为太阳能驱动的无线传感器网络提出了一个新的基于模糊逻辑控制的路由算法。该算法综合考虑最优节点质量，传输能力以及剩余能量的泰勒均衡性最终确定最优路由路径。实验将该算法与另外两种经典路由算法做对比，并且比较了不同均衡性参数下该算法的性能，最后仿真结果表明：本文提出的路由算法改善了能耗有效性和均衡性，延长了网络生命周期。

Resource limitation and unbalanced energy consumption are two main factors to limit the lifetime for Wireless Sensor Networks(WSNs).This paper first introduced a new metric indicating degree of balance,called Theil index,and then proposed a new routing method for solar powered WSNs to extend network lifetime using a fuzzy approach which is to determine an optimal routing path by favoring the node with the highest Node Quality (NQ),largest Transmitting Capacity(TC)and best Degree of Energy Balance(DEB)of Theil index.This paper vali-dated the proposed method with simulations and made comparisons with other two classic routing algorithms and fi-nally compared the performance under three different DEB indexes,which demonstrated that the proposed method has a better effectiveness and balance of energy consumption,prolonging the network lifetime.
