摘要: 由于矿井无线Mesh网络(WMN)多媒体应急通信系统的多跳传输存在基准带宽较低、多跳传输带宽衰减率较大的问题,对其多跳传输性能进行改进。提出了一种矿井WMN多媒体应急通信系统骨干传输链路的网络结构,并建立了其传输模型,研究了对其传输性能产生影响的主要因素。提出了基于802.11n的多跳Mesh骨干传输网络的多模Mesh节点结构,解决了矿井WMN多媒体应急通信系统多跳传输的两个难题。实验结果表明其具有超过165Mbps的基准带宽,并且在60Mbps的限速应用环境下,每跳的带宽衰减小于1%,基本满足了矿井多媒体业务传输的应用需求。

Abstract: The multi-hop transmission of multimedia emergency communication system based on Wireless Mesh Network (WMN) in underground mine have two problems: low basis bandwidth and high multi-hop transmission attenuation. This paper aimed to improve the multi-hop transmission performance for the system. In this paper, a trunk line network structure of multimedia emergency communication system based on WMN in under-ground mine was proposed. The authors established its transmission model, and then had a research on the main factors that affected the transmission performance. The multi-radio node structure of multi-hop mesh backbone network based on 802.11n was proposed and solved the two problems of multi-hop transmission. The experimental results show that it has more than 165Mbps basis bandwidth, and under the limited 60Mbps environment, the bandwidth attenuation of per hop is less than 1%, basically satisfying the application requirements of multimedia transmission in underground mine.

Key words: 802.11n, emergency communication system, multi-radio, Wireless Mesh Network (WMN), multi-hop transmission performance
