Research on the trunk line's transmission performance of multi-hop WMN based on 802.11n

Abstract

This paper had a research on the main factors which affect the transmission performance. Based on 802.11n, It proposed the multi-radio node structure of multi-hop Mesh backbone network, achieved the prototype system of wireless mesh router, and solved the two problems of multi-hop transmission: multi-hop attenuation and basis bandwidth bottlenecks. The experiment showed that it had more than 165 Mbps basis bandwidth, and under the limited 60Mbps environment, the bandwidth attenuation of per hop is less than 1%, which basically satisfied the application of on-board Internet. © 2012 Springer-Verlag GmbH.
