均衡网络能量消耗并提高网络生存周期是无线传感器网络路由研究的一大挑战.针对现有分簇路由算法的不足,本文提出了一种新的基于竞争机制的无线传感器网络分簇路由协议(CMCRP).该路由协议在簇头选择中引入竞争机制,当节点剩余能量高于网络平均能量设定值时,节点竞争为候选簇头,同时引入节点间的拟物力作用对阈值加以调整,以均衡网络中簇的分布;在簇形成过程中,普通节点根据通信代价及与簇头的拟物力依概率成簇.与现有协议比较结果表明,CMCRP算法在均衡网络负载,延长网络寿命等方面具有良好的性能.

One of the challenges in the study of the routing of wireless sensor network is to balance the network energy consumption and improve the network lifetime. In view of the drawbacks of the existing clustering routing algorithms, this paper proposes a novel one called CMCRP based on competition mechanism. This routing protocol introduces competition mechanism in head selection. When the node residual energy is higher than the set point of the average energy of the network, the node competes to become a candidate of the cluster head and the apphcation of quasi physical-force between the nodes adjusts the threshold in order to balance the distribution of the network cluster. While forming of the formating cluster, ordinary nodes ate considered to consist of cluster formation according to communication cost or the cluster-head to quasi physical-force by probability. Comparing with the existing protocols, the result shows that CMCRP algorithm has a better performance in balancing network load and extending the network lifetime.
