【摘要】 无线传感器网络中节能、能耗均衡等是延长传感器网络寿命的关键。本文在各层节点平均能耗相等的基础上提出了多跳非均匀分簇路由算法(MUCR),核心为由远及近依次求取各层成簇半径值,使得靠近sink节点的成簇半径小于远离sink节点的成簇半径;通过外层节点触发内层节点开始成簇,建簇的同时利用转发节点形成多跳路由;依据接收比特值和簇首节点剩余能量发起簇重构。在Omnet++仿真平台下模拟实验结果显示,MUCR有效地均衡了全网节点能耗,显著延长了网络生命期。更多还原

【Abstract】 Energy-efficient and energy balance is the key issue in wireless sensor network to extend the network’s life.In this paper,Multi-hop Uneven Clustering Routing algorithm(MUCR) is proposed based on equality of the average power consumption,and the main idea is to strike a value of cluster radius in every level from the most far level to the nearest one,and make the radius of the clusters near the sink node less than the radius far from the sink node;cluster is building by outer nodes to trigger the inner node,and form a multi-hop routing by using cluster gateway nodes at the same time;cluster is rebuilding based on received bit value and the residual energy of cluster head.The results of simulations in OMNET ++ show that MUCR improves obviously in balancing energy consumption between nodes and prolonging network’s life period.更多还原
