在Linux平台下以开源代码构建多跳Mesh网络实验床,对其传输带宽随无线跳数的增加而急剧下降的关键问题展开深入分析和实验研究。实验结果表明,采用提出的优化方法构建的增强型多模Mesh网络,其带宽下降问题得到了根本上的解决,并且回传链路带宽提高到60Mbp/s以上。
A multi-hop Mesh testbed is constructed on the Linux platform based on the open source code. Within this testbed, serials of experiments are carried on to analyse the key question of multi-hop Mesh network, which is the bandwidth decreased seriously with the wireless hops increasing. Experiment results show that this question is resolved by the advanced multi-radio Mesh model, an open approach proposed by this paper. At the same time, the bandwidth of the backbone of Mesh network is promoted to 60 Mb/s.
