摘　　要：WiFi技术由于成本低,性能稳定,易于部署等一系列优点,被广泛地应用于短距离传输。但在长距离应用过程中存在隐藏节点问题,导致网络中某些站点无法传输数据,限制了其更广泛的应用。文中针对WiFi长距离传输隐藏节点问题,通过引入TDMA协议,使得WiFi在远距离传输各个站点获得相同传输机会,解决远距离传输时某些站点无法获得传输机会的问题。WiFi technology is widely used in short-distance transmission due to a series of advantages such as low cost,stable performance,and easy deployment.However,in the long-distance application process,there is a problem of hidden nodes,which causes some stations in the network to be unable to transmit data,which limits its wider application.Aiming at the problem of hidden nodes in WiFi long-distance transmission,the introduction of the TDMA protocol allows each station to obtain the same transmission opportunity during long-distance transmission,and solves the problem that some stations cannot obtain transmission opportunities during long-distance transmission.
