摘　　要：针对矿山开采过程网络受损等意外情况发生时的通信网络拥塞,导致视频、语音、指令等信息传输链路容易中断的问题,提出了一种用于矿山应急通信的的无线Mesh网络,从传输层研究网络的接入节点(Access Point,AP)选择算法。首先,以无线Mesh网络的端对端整体回传延时作为优化目标,通过传输层延时情况判断当前的传输链路是否中断或带宽严重下降的紧急情况。其次,引入临近AP广播选择机制(Broadcast Selection Mechanism of Adjacent AP,BSM-AP),使设备通信终端不需要预先关联AP即可计算不同AP的回传信息延时,降低系统测量与算法选择的开销。最后,使用模糊逻辑方法选择接入一个综合性能最优的AP迅速重传信息。通过高通样机平台上植入算法测试井下通信信息的传输成功率,试验结果表明:所提算法可以大幅降低关键救援信息的网络时延,并保证传输的可靠性。In order to solve the problem that video,voice,command and other information transmission links are easily interrupted due to the congestion of communication network when accidents such as network damage occur in the mining process,a wireless Mesh network is proposed for mine emergency communication,and the Access Point(AP)selection algorithm of network is studied from the transport layer.Firstly,the end-to-end global transmission delay of the wireless Mesh network is taken as the optimization objective,and the transmission layer delay is used to determine whether the current transmission link is interrupted or the emergency situation of serious bandwidth decline.Secondly,Broadcast Selection Mechanism of Adjacent AP(BSM-AP)is introduced so that communication terminals of the equipment can calculate the delay of information return of different APs without pre-associated AP,and reduce the overhead of system measurement and algorithm selection.Finally,the fuzzy logic method is used to select and access an AP with optimal comprehensive performance.The algorithm implanted on the Qualcomm prototype platform was used to test the transmission success rate of downhole communication information.The test results show that the proposed algorithm can greatly reduce the network delay of critical rescue information and ensure the reliability of transmission.
