Link Quality Based Sub-Cluster Routing for Wireless Sensor Networks
无线传感器网络的链路评估分簇路由算法

A Link quality based sub-cluster routing for wireless sensor networks is proposed.The new algorithm utilizes a link quality evaluation model in Gauss distribution,link quality is taken into accout in selecting cluster head,In addition,a dynamic window is presented to record the realtime link information.Simulation results indicate that compared with LEACH and HEED,the adoption of link quality based routing metric can provide longer network lifetime and higher reliability of the data transmission.
