多径路由协议可以同时使用多条路径传输数据,减少端到端延迟并提高吞吐量。然而,多条路径之间的干扰作用可能会对网络的整体性能造成影响,使网络无法实现预期的性能提升。提出了一种新的解决路径间干扰问题的算法IO-AOMDV(Interference-OptimizedAOMDV)。该方法引入路径相关度的计算来评估路径间干扰的大小,在路由发现过程中发现并建立路径相关度最小的路径对,然后使用该路径对传输数据。仿真结果表明,IO-AOMDV在包投递率、吞吐量、端到端平均延迟三个指标上可以得到较好的网络性能。

Using multiple paths to transmit data simultaneously in Ad-Hoc network is regarded to reduce end-to-end delay and achieve higher throughput. However,the interference between these paths may make a difference to the overall performance of the network,not completing the expected performance raising. A new protocol ( IO-AOMDV) was proposed to establish interference-minimized paths. The protocol uses a new algorithm which can evaluate the extent of paths-interference to establish the interference-minimized paths,then uses these paths to transmit data. Simulations show that IO-AOMDV achieves good performance in terms of packet delivery ratio, throughput and average end-to-end delay.
