摘要 以链路作为网络图的考察点构建无线多跳干扰图模型,据此分析无线Mesh网络容量优化问题,将网络性能优化转化为图论中的"网络最大流"问题。从网络负载的均衡控制、多跳转发的路由优化、链路速率的自适应方法 3个机制着手对无线Mesh网络协议进行优化。理论分析与仿真实验结果表明,该模型的误差率可控制在10%以内,有效提升Mesh网络性能。 A multi-hop interference graph model is proposed which takes wireless link as a diagram in this paper.And capacity optimization formulated as ＂maximum flow problem＂ is analyzed based on this graph.It presents three optimization mechanisms to improve network protocol,such as ＂load-balancing＂,＂routing algorithm＂,＂rate adaption＂.Theoretical analysis and simulation results show that the error rate of the model can be controlled within 10%,effectively improve mesh network performance.
