中文摘要：
提出了一种基于簇首节点的可信传感器网络路由协议TRPBCH，对解决条件受到较大限制的无线传感器网络路由感染十分有效。TRPBCH协议包含簇首信任可用机制和簇首轮换选举机制；簇内可信路由机制、信任机制和问题节点搜索与隔离机制。TRPBCH协议有3个核心模块：可信路由模块TRM、问题节点归避模块TNAM和簇首管理模块CMM。通过实验设计实现了TRPBCH协议的3个核心模块，仿真实验表明：TRPBCH协议能有效地隔离问题节点，解决路由感染问题，提高有效发包率。
英文摘要：
A trusted routing protocol based on cluster head （TRPBCH）for wireless sensor networks is presented, which can provide a method of secure routing with WSNs of great restriction. TRPBCH contains two parts of the mechanism：cluster head and the part of internal cluster, the part of cluster head includes trust and availability mechanism and rotation and election Mechanism, and the part of interual cluster includes trust routing mechanism, trust mechanism and trouble node searching and avoidance mechanism. TRPBCH is made up of three core modules, trust routing module （TRM）, trouble node avoidance module （TNAM）and cluster manage module （CMM）. And also, the three core modules of TRPBCH are designed and implemented. Simulation results show that the TRPBCH can effectively avoid trouble nodes and solve the problem of route infection, and raise the effective rate of data packages.
