依托路由规则的自适应能量优化分簇无线传感器网络路由算法

摘要

For cluster nodes in wireless sensor networks energy load imbalance to cause cluster head to early death in the case of more tasks,and routing problem such as larger energy loss,this paper proposed an adaptive energy optimization clustering routing algorithm.Fully considering the node residual energy and distance by the weigh coefficient on the cluster head election and competition radius calculation,which achieved prolong the life cycle of the cluster head.Forwarding data between the pro-visions of the cluster head is to use more than one hop routing or hop routing by the form of the routing rules,to maximize re-duce the energy loss in the routing in the case of cluster does not guarantee the early death.%针对分簇无线传感器网络中节点能量负载不均衡导致簇头在任务较多的情况下过早死亡，以及路由能量损耗较大等问题，提出一种自适应能量优化分簇的路由算法。在簇头选举和竞争半径的计算上通过权衡系数充分考虑了竞选节点的剩余能量与距离情况，延长了簇头的生命周期。以路由规则的形式来制定簇头间转发数据是采用单跳路由还是多跳路由，在保证簇头不会过早死亡的情况下最大化减少路由的能量损耗。实验仿真结果表明，自适应能量优化分簇的路由算法可以延长网络节点的生命周期，减少能量损耗。
