摘要： 为提高无线Mesh网络(WMN)的可靠性，以可信计算领域中的拜占庭容错原理为基础，引入拜占庭单元概念，构建一个WMN拜占庭容错网络结构，并提出一种拜占庭算法，用以改进现有WMN路由协议。仿真结果表明，改进的路由协议能对异常节点信息进行容错处理，获得正确的节点信息，增强网络的容错能力，达到提升WMN可靠性的目的。

Abstract: In order to improve the reliability of the Wireless Mesh Network(WMN), in the field of Byzantine fault-tolerant computing based on the principle, this paper puts forward the concept of Byzantine unit to construct a WMN Byzantine fault-tolerant network structure. On the basis of this structure, this paper proposes a Byzantine Algorithm(BA) to improve the existing WMN routing protocol. Simulation results show that improved routing protocols can adopt the abnormal node fault-tolerant information processing, get the correct node information, remove interference and enhance the network fault tolerance, and reach the goal of raising the WMN reliability.
