摘要
针对无线传感器网络中的信息时延和网络生存周期较短等问题,提出了基于质心的CMC-PEGASIS(center of mass concept in power efficient gathering in sensor information system)路由协议;该协议将区域分为等宽的5部分,利用PEGASIS的理念对其各自成链;而后利用质心的概念找到区域节点的能量中心,并结合节点自身的能耗以及节点与基站的距离关系得到区域内最佳的簇头节点;仿真实验表明,该协议有效地平衡了整个网络的能量消耗,并且延长了网络的生存时间。
The longer information delay and the shorter network life cycle are the problem in the wireless sensor network.CMC-PE-GASIS （center of mass concept in Power Efficient Gathering in Sensor Information System） routing protocol is presented based on center of mass concept.WSN is divided into five parts in the agreement,using the concept of PEGASIS to make chain in every part.Then according to the concept of center of mass to find regional node energy centers and combing the node energy consumption with distance from node to base station to get the best cluster node.Simulation experiments show that the protocol effectively balances the energy consumption of the entire network,and prolotng the survival time of network.
