两种短波跳频网络信道接入协议仿真

Simulation on Two Channel Access Protocols in Short Wave Hop-frequency Network

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。

HF is an important communication means in military communication and emergency communication. The hop-frequency and networking technique could greatly improve the anti-jamming and anti-destroying capability of HF communication. In HF networking, the channel access protocol could determine the network performance. For short wave hop-frequency networking, two channel access protocols are proposed, including multi-channel fixed slot TDMA protocol and alternate channel TDMA protocol, and these two protocols are, modeled and simulated with OPNET Modeler. The processing and analyzing of the simulation data indicates that the performance of these two TDMA protocols could be applied in short wave hop-frequency networking.
