一种基于分簇蚁群策略的无线传感器网络路由算法

如何最大化地延长网络的生存时间是无线传感器（WSN）网络研究的核心问题.基于分簇策略,提出一种能量有效的路由算法（EEA）.该算法利用分簇原理减少了参与寻找最优路径的节点数,从而降低了系统的能耗.同时设计一种改进的最优路径评价标准,该标准兼顾了传输路径上各节点的剩余能量和最优路径上总的能量消耗.仿真结果表明,与其他蚁群策略的路由算法（如：基于蚁群算法的路由算法（ARA）和EEAWSN）相比,该算法能在寻找最优路径时避开剩余能量少的节点,使最优路径上各节点的能量呈整体性衰落,从而沿长了网络的寿命.

An energy efficient routing algorithm based on clustering and ant colony optimization for wireless sensor networks

How to make efficient use of the limited energy of nodes so as to prolong the lifetime of the wireless sensor network(WSN) is an important problem.An energy efficient routing algorithm(EEA) based on clustering is presented.This algorithm uses clustering to reduce the number of nodes which join in researching route,which can reduce consumer energy.The improve route optimal degree is presented to evaluate the performance of the chosen route.Simulation results show that,compared with other algorithms,like ant colony optimization(ACO)-based routing algorithm(ARA) and EEAWSN,the proposed approach is able to keep away from the node with less residual energy,which can improve the life of networks.
