摘要
无线传感器网络是由能量有限的节点组成,高效节能的路由算法是无线传感器网络的基础。针对低功耗自适应分簇(LEACH)路由算法在选择簇首节点及通信过程中能量消耗大的不足问题,提出了一种改进的LEACH路由算法。引入节点剩余能量因素参与簇首节点的选择,有效地降低剩余能量较小的节点成为簇首的可能性,节点之间的数据传输采用单跳和多跳相结合的通信方式,也降低了传感器网络能耗。
Wireless sensor networks are composed by the nodes with limited energy, energy--efficient routing algorithm is the base of wireless sensor networks. Because low power Adaptive clustering （LEACH） routing algorithm has some shortcomings and problems in selecting cluster head node and in the process of communication, so an improved LEACH routing algorithm was put forward in this paper. Introducing the node of residual energy factors involved in the choice of cluster head node, reducing the possibilities of the smaller nodes of residual energy effectively to become into cluster head, the date transfer between the nodes adopt the combination of single-hop and multi-hop communication, reducing the energy consumption of sensor networks.
