摘要： 在无线传感器网络应用中,节点间通信的质量和能耗都受到链路质量因素的影响。提出了基于链路质量的层次型路由协议(EBCLQ),该协议由网络初始化、簇形成、数据传输3部分组成。网络初始化算法NIL利用LQEWAL链路质量预测方法来获取节点间链路质量和邻节点信息,以为后续工作做准备；簇形成包括基于链路质量和能量的候选簇头产生算法CCELE、正式簇头确立算法FCECC以及簇建立；EBCLQ协议在数据传输阶段提出了簇内时隙分配算法SAL和簇间单跳与多跳相结合的算法MOCC。最后,通过MATLAB,在仿真环境下实现了EBCLQ协议,并通过比较和分析其在网络中的执行效率证实了EBCLQ协议的有效性和均衡性。
