摘要
针对无线传感器网络路由能量消耗不平衡,导致整个网络过早死亡的问题,提出一种基于模糊多属性决策(FMADMR)的WSN路由算法。方法使用主观权重和客观权重相结合的方法确定属性权重,综合节点的能量、方向、可靠性等属性进行评价,通过模糊值排序算法选择转发节点,最终形成路由路径。仿真结果验证了该算法在平衡网络的能耗,延长网络生存时间等方面表现出良好的性能。
A Fuzzy Multiple Attribute Decision Making Routing(FMADMR) algorithm in wireless sensor networks is proposed to avoid the unbalanced energy consumption.This algorithm determines weight by the method of combining subjective weight and objective weight.A sensor node can choose a forward node by the method of fuzzy sorting depending on the evaluation of the energy,the directions and reliability of its neighbor nodes to form a path.Simulation results show that this algorithm has good performance on balancing the energy consumption and prolonging the lifetime of the network.
