一种基于位置和能量的WSN改进分簇协议

针对LEACH分簇路由协议中簇首随机选择,没有考虑节点的剩余能量和地理位置,可能导致分簇和网络能耗不均衡这一问题,研究了一种同时考虑了节点位置和剩余能量信息的改进分簇路由协议,使成为簇头的节点在簇的中心位置,从而使簇头在簇内的位置更加合理,避免了簇内的部分节点由于离簇头过远,增加传输损耗的缺点,有利于网络性能的提高。仿真结果表明,研究的分簇路由协议能使簇的划分更加均匀,能量的消耗更加节省,从而延长了WSN网络的生存时间。

A WSN Improved Clustering Routing Protocol Based on Location and Energy

In LEACH protocol, the cluster heads are randomly selected, without taking account of the remaining energy and location information, thus making the clusterheads badly-distributed and the energy-consuming of the whole network unbalanced. For these problems, an improved clustering routing protocol in consideration of looth location and remaining energy of the nodes is proposed, which makes the clusterheads located in the center of the cluster, and the location is more reasonable, thus avoiding some nodes being too far from the clusterhead.The simulation of the proposed routing protocol indicates that the clusterheads are well distributed, the energy consumption is even less, and the lifecycle of the whole network is obviously prolonged.
