CSMA-BT Protocol for Intra-Flight Data Link

The intra-flight data link is a new dedicated tactical data link used in the aircraft formation to transmit tactical information. A multiple access protocol for intra-flight data link called CSMA-BT (Carrier Sense Multiple Access based on Busy Tone) is proposed in this paper. By analyzing time delay performance of CSMA-BT protocol, the results show that CSMA-BT can meet combat requirement of intra-flight data transmission well.
