【摘要】 以无线Mesh网络多接口多收发器MAC模型为基础,从理论上分析了HOP、ETX、ETT、WCETT、INX等典型路由判据的性能,并通过NS2对各路由判据在网络吞吐量及丢包率方面的性能进行了实验仿真。研究结果表明,INX在网络吞吐量方面的性能明显优于其它几种路由判据,但INX并没有考虑到数据流内干扰,且随着网络负载的增加,其丢包率将过高。更多还原

【Abstract】 This paper, based on multi-interface multi-radio wireless mesh networks transceiver MAC model, analyzed the performance of HOP, ETX, ETT, WCETT, INX from the theory, and then used the NS2 to simulate the performance of the routing metrics in network throughput and packet loss rate. The results showed that the performance of INX was better than others in network throughput, but INX did not take into account of the intra-flow interference, and with the increasing of network load, the packet loss rate increased heavily.更多还原
