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.
