Research on Reliability Optimization Method for Mesh Network Communication Based on Node Congestion Degree

Using wireless mesh network characteristics of multi-hop networks, self-organization and other features, to improve the question of the overlarge quantities of communication task, uneven use of resources lead to the problem of low reliability of network communication. Analyze the factors which affect network reliability in the processes of information communication. And combine with bandwidth, node cache and node processing speed. A method based on controlling node congestion degree, optimizing network resource utilization and improving communication reliability was presented. Balance the conflict between low loss rate and high throughput. Set up a wireless Mesh network communication reliability optimization model. Using genetic algorithms (GA) for simulation, verify that the method is effective and feasible.
