| 摘 要： | 以锚节点与监测区域相距很远的无线传感器网络为研究对象,提出了一种能量均衡的组播路由算法.该算法分成两个阶段:在第一阶段,前向转发区域内的候选节点通过依据自己的剩余能量及到接入点的距离设定定时器来竞争转发数据包;在第二阶段,算法在多播区构建一棵以接入节点为根节点的组播树,树中的节点根据当前父节点及候选节点的剩余能量更新父...

| Abstract: | An energy-balancing multicast routing algorithm is proposed for a WSN scenario,in which the sink node is probably far away from the monitoring area.This algorithm has two steps:in the first step,each node in the forwarding area contends for relaying packets by setting its timer according to its residual energy and the distance to the access point;in the second step,a multicasting tree rooting from access point is constructed among nodes in the multicast area,and nodes in this tree updating their parent node... |
