无线多接口多信道Mesh网络下多径路由协议分析

针对无线多接口多信道Mesh网络环境,对两种多径路由模型进行比较分析。根据支持多接口多信道的无线设备的特点,提出了一套较为高效的路由方式。该方案从源节点到目的节点利用提出的接口分配策略,从不同的接口和信道建立多条可同时工作的路由和多条不重叠的备份路由以大幅提升网络性能。它充分利用了多接口多信道移动设备的性能优势,更适合Mesh网络的拓扑特点。仿真测试表明,使用该方案,在端到端时延,网络吞吐量等方面提供了更佳的性能。

Analysis of Multi-path Routing for Multi-interface Multi-channel Wireless Mesh Networks

Based on the multi-interface multi-channel wireless mesh network environment,two multi-path routing model are analyzed.According to the features of wireless devices that support multi-interface and multi-channel,propose a more efficient routing model.Using the proposed interface assignment from source node to destination node,the program establishes multi-ple route working simultaneously and multiple non-overlapping backup route to significantly improve network performance from different interfaces and channels.It makes full use of performance advantages of multi-channel multi-interface mobile devices,thus it is more suitable for topology characteristics of mesh network.
