摘要/Abstract

摘要： 针对多接口多信道MANET网络环境，提出了一种多径路由以及相应的接口分配策略。根据支持多接口多信道的无线设备的特点，给出了一套更为高效的路由模型。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，更适用于网络拓扑变化剧烈的MANET网络。数学模型分析与网络仿真测试表明，在其他条件相同的情况下，该方案与其他路由协议相比较，在端到端时延、网络吞吐量等方面提供了更佳的性能，且更适应于多接口多信道的MANET网络环境。

Abstract: A multi-path routing and interface assignment is proposed for multi-interface multi-channel MANETs.According to the characteristics of wireless devices which can support multi-interface multi-channel，a more efficient routing model is proposed.This proposal，which can provide much better performance，builds multiple paths via different interfaces and channels from the source to the destination，and also builds multiple backup paths.It takes full advantage of the performance of multi-interface multi-channel mobile devices，and is much better to adapt to poignant changes in the network topology，such as MANET.Mathematical analysis and simulation tests indicate that under the premise of other conditions being the same，it provides better performance in end-to-end delay and throughput of network compared with the other routing protocols.What’s more，it better adapts to multi-interface multi-channel MANETs.

Key words: multi-interface multi-channel, Mobile Ad-hoc Networks（MANET）, interface assignment, multi-path routing
