| 摘 要： | 将IEEE802．11的RTS／CTS握手机制与MSDU帧分段机制引入地空数据链，建立了基于改进Markov链的地空数据链MAC层协议模型。以最大饱和吞吐量为性能参数推导出合理的RTS阈值和分段阈值算法。分析表明该方法能够提高无线通信效率，降低了误帧率，解决了隐藏终端等问题。

| Abstract: | RTS/CTS handshake mechanism and frame fragmentation mechanism are introduced into ground-to-air data link,MAC protocol based on modified Markov chain is built,and two thresholds algorithms which lead to the best saturated throughput are derived.Analysis shows that it could improve wireless communication efficiency,reduce frame error rate and figure out the problem of hidden terminal. |
