摘要
无线传感器网络中,基于分簇的路由算法是节点在执行数据通信功能前提下尽可能延长网络的寿命的有效手段。针对现有路由算法EEUC存在的扩展性能差、临时簇头选择未考虑能量、部分节点无法加入任何簇的问题,对成簇算法、节点竞争半径等方面进行改进,以提高算法的执行效率。仿真结果表明改进后的I-EEUC算法更能节省节点的能量,以至延长网络的存活时间。
Clustering-based routing algorithm is an effective means to prolong lifetime for the wireless sensor networks when nodes perform data communication.According to problems existing in EEUC routing strategy,such as poor scalability,not considering energy for the temporary cluster head selection and some nodes not join any cluster,improvement on the clustering algorithm as well as the competition radius for nodes is proposed so as to advance efficiency of the algorithm.Simulation results show that proposed I EEUC saves more energy than EEUC,and prolong the survival time of the network.
