基于能量分簇的传感器网络路由机制

Clustering Routing Mechanism for Wireless Sensor Networks Based on Energy

无线传感器路由协议采用分簇方式对网络的扩展特别有效,当簇首以多跳方式进行向汇聚点通信时,靠近汇聚点的簇首由于转发外层簇首信息造成能量消耗过快,导致网络分割。本文采用能量消耗平衡化的方法来解决此问题,它的核心是能量损耗快的簇以减小簇面积来降低本簇传感器能量消耗,从而促使网络传感器节点能量消耗的平衡性,以至网络存活时间得到最大的保障。通过试验结果验证,该路由机制有效的平衡了簇首能量的消耗,并显著的延长了网络存活时间。

Using clustering techniques in routing protocols of wireless sensor networks is special available for scalability of networks. When cluster heads transmit their data to the data sink via multi-top communication,the cluster heads closer to the sink are bur- dened with heavy relay traffic and tend to die early,causing network partitions.This paper resolves the problem by balance of energy use ,its core is that sensor of the networks achieve evenly energy use by reducing area of cluster whose speed of energy use is quicker than the others,so as to increase lifetime of networks .Simulation results show that the routing mechanism effectively balances the energy consumption among cluster heads and achieves an obvious improvement on the network lifetime.
