摘要： 分簇思想是设计能量高效的无线传感器网络路由协议的一种重要方法。在分析iHEED协议的基础上，通过仿真实验和理论分析，指出iHEED协议可能出现“成簇父节点丢失”现象。针对该现象提出并在TinyOS上实现了iHEEDCHLevel分簇路由协议，引入“分层成簇”思想对iHEED协议进行了改进。TOSSIM模拟仿真表明，iHEEDCHLevel协议是有效的，它实现了层次分簇，保证了簇间多跳数据传输链路的建立。

Abstract: Clustering is an important method to design the energy efficient routing protocols in wireless sensor networks. This paper analyzed the principles of the iHEED protocol and pointed out the "parent node loss after clustering" phenomenon by simulation and theoretical analysis. For imporving the iHEED protocol, the "clustering by node level"was introduced and implemented on TinyOS named iHEEDCHLevel protocol. From simulation using TOSSIM, it shows that the iHEED-CHLevel protocol is effective on clustering by node level and guarantees the setup of routing tree among the cluster heads for aggregated data transfer.
