Abstract Based on directional antenna, the capability of the intra-flight data link such as anti-jamming and low interception can be greatly improved. However, it also brings some problems: obtaining the destination node location information, meeting the real-time requirement of the burst traffic and sharing situation information with directional antenna, etc. To solve the problems, DP-CLMA (Dynamic Priority-Chain Link Multiple Access) protocol based on directional antenna is proposed, and some corresponding mechanisms are described in detail. By analyzing time delay performance of DP-CLMA protocol, the results show that DP-CLMA protocol adapts to intra-flight tactical data transmission.
