针对军事航空自组网中实时通信对时延、传输可靠性的要求，提出了一种基于突发技术的多信道MAC协议---BT-MAC。采用多信道、突发技术和异步跳频机制，有效减少了分组端到端时延，同时使系统具有一定的抗干扰能力。仿真结果表明，理论分析与仿真值基本一致，与TDMA协议相比较，时延性能明显更优。

A multi-channel MAC protocol based on burst technology ( BT-MAC) was proposed according to the requirement of military aeronautical Ad Hoc network to the time delay and transmission reliability in real-time communication .By using the mechanism of multi-channel,burst technology and asynchronous frequency hopping,the time delay of packets was decreased effectively ,and the system was provided with the capability of anti-jamming.Simulation shows that the theoretic analysis result is basically the same with the simulation result,and the time delay performance of BT-MAC is obviously better than that of TDMA .
