摘　　要：提出了一种链路评估分簇路由算法(LQ-CR),该算法利用基于高斯分布的链路质量评估模型,将无线链路质量作为簇首选择度量,并采用滑动窗口机制实时评估链路质量。仿真实验表明,与LEACH、HEED分簇协议相比,采取链路质量作为路由度量可以有效延长网络的生命周期,提高数据传输可靠性。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.
