摘要
为了解决节点高速移动和复杂的网络环境引起的地空数据链存在的隐蔽终端、频移、丢包以及编码错误等问题,提出2个重要的MAC层通信机制——MSDU(MAC services data unit)帧分段机制和RTS/CTS(request-to-send/clear-to-send protocol)握手机制。从小业务量和多业务量2个角度设置仿真实验并给出仿真分析。实验证明,MAC层通信机制能够有效解决隐藏终端等问题,并提高网络性能。
In order to deal with the hidden terminal, frequency shift, drop-package, errors of ground to air data link arising from high speed movement of node and complicated network environments, two important MAC communication mechanisms：the MSDU frames subsection and RTS/CTS handshake mechanism are proposed. Then some simulation experiment from low traffic and high traffic aspects have been set up and analyzed. Results show that MAC mechanism may resolve issues above effectively and improve the performance of networks.
