【摘要】 目前主要的无线传感器网络分簇路由协议的提出都是基于节点均匀分布、能量均衡消耗等理想化的假设,而这些假设在网络处于实际工作环境时往往导致簇首选取的不合理。针对该问题,提出一种能量有效的分布式簇首选取算法,在选取簇首时综合考虑网络的拓扑特性及网络中各节点能耗等因素。实验证明,采用该算法的传感器网络具有较好的适用性,其使用寿命较LEACH等传统的算法提高了1倍以上。更多还原

【Abstract】 At present,the major Wireless Sensor Network(WSN) clustering routing protocols proposed are based on uniform distribution of nodes,the energy balance of consumption idealized assumptions,but in a real work environment,these assumptions often lead to cluster preferred to take unreasonable.To address the above issues,an energy efficient distributed cluster heads selection algorithm of sensor networks is proposed.When selecting cluster heads,the algorithm considers various factors such as the network topology characteristics and the node’s energy consumption.Simulation results show that sensor network using this algorithm has better applicability and its useful life improves over doubled than traditional algorithms such as LEACH.更多还原
