Research On Reliable Routing Technology In Wireless Mesh Networks

The Wireless Mesh Networks(WMN) is based on the multi routing, multi peers to multi peers. It is dynamic expansion, ad hoc networks, self-management, self-healing, mobile broadband with high-capacity, high-speed, and can be used as last-mile network to solve the bottleneck problem. It also is low investment, incremental deployment, easy maintenance, network robust and reliable range of services. All the advantages firm its core status in future wireless communications domain.The Byzantine Generals Problem is a fault-tolerant principle in trusted computing; the principle can make the system still be able to work unaffected with one or more system components abnormal. It has a wide range of applications in trusted computing, fault tolerance and network security.In this paper, according to the characteristics of Byzantine theory, analyze the feasibility of principles applied to network reliability. Then according to the structural characteristics of the WMN, giving the adaptive Byzantine structure, and then construct suitable Byzantine algorithm for the WMN. The algorithm including WMN backbone nodes in the search, the establishment and the maintenance of the Byzantine unit, it also includes selecting the backup data storage and fault-tolerant judgments, and, it shows the special circumstances of the strategies.This paper also gives two kinds of network protocols of strategy formulation BAODV protocol and BDSR protocol by the agreement on the WMN improvements, and the analysis on different routing protocols to improve the actual situation of different backup examples of fault-tolerant effect. Finally, through simulation experiments, pairs of routing protocols to improve the performance, verify routing protocols to improve the relevance, effectiveness and advantages.
