| 摘 要： | 针对无线传感器网络中考虑能量均衡问题,提出了一种基于分环多跳的路由加权算法(ring based multi-hop clustering routing weighting algorithm,RMCRW)。算法在簇头节点向内层转发的过程中,不仅考虑与内环簇头的距离,同时考虑内环簇头剩余能量问题,通过加入一个权值,选择最优簇头转发路径。仿真结果表明在区域范围比较大的环境下,RMCRW算法可以有效地延长网络生命周期。

| Abstract: | A ring based multi-hop clustering routing weighting algorithm(RMCRW) was proposed to keep energy balance in the wireless sensor networks.This algorithm considered not only the distance between the inner layer cluster heads,but also the remaining energy of them in the process of relaying data to the inner layer.As a result,the optimal paths could be selected according to the weight.The simulation results proved that the RMCRW algorithm could effectively prolong the network lifetime in large area. |
