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.
How to maximize the lifetime of the network is a key issue in wireless sensor networks (WSN) research.An efficient and energy-efficient routing algorithm (EEA) is proposed based on the clustering strategy.This algorithm uses the clustering principle to reduce the number of nodes involved in finding the optimal And reduce the energy consumption of the system.At the same time, design an improved evaluation criteria of optimal path, which takes into account the residual energy of each node in the transmission path and the total energy consumption in the optimal path.The simulation results show that Compared with routing algorithms of other ant colony strategies (such as ARA and EEAWSN), this algorithm avoids the remaining nodes with less energy when searching for the optimal path, The energy of each node showed a decline, thus extending the life of the network.
