短波通信是军事通信、应急通信的一种重要通信手段。使用跳频技术、组网技术能极大地提高短波通信的抗干扰、抗毁能力。在短波跳频组网中,信道接入协议对网络的性能起着决定性的作用。针对短波跳频组网,提出两种TDMA信道接入协议:多信道固定TDMA协议和轮值TDMA协议,并应用OPNET仿真工具对这两种协议进行了建模、仿真。通过处理和分析仿真数据,比较了两种协议的性能。两种协议均可用于短波跳频组网。
Shortwave communication is an important means of communication for military and emergency communications. Using frequency hopping technology, networking technology can greatly improve the anti-interference, anti-destruction ability of shortwave communications. In shortwave frequency hopping network, channel access protocol plays a decisive role on the performance of the network. For shortwave frequency hopping networking, two TDMA channel access protocols are proposed: multi-channel fixed TDMA protocol and round robin TDMA protocol, and the OPNET simulation tools are used to model and simulate the two protocols. By processing and analyzing the simulation data, the performance of the two protocols is compared. Both protocols can be used for shortwave frequency hopping networking.
