Aeronautical High-speed Ad-hoc MAC Protocol

Nodes in Aeriaonautical High-speed Mobile Self-organized Networks move fast, so the network topology changes quickly and communication links can be invalid in a very short time. The MAC protocol of traditional self-organized network is hard to deal with these problems.Considering the features of High-speed Mobile Self-organized Networks, this paper proposed a new protocol algorithm PDC-TDMA based on network topology prediction. In this algorithm, data is transmitted according to the predicted network topology which is obtained by the control information interacted among nodes. Thus, the packet loss probability is decreased.The aerial High-speed mobile self-organized network simulation model is built in Opnet, and scenarios with different movement speed network load are studied. The simulation results show that PDC-TDMA protocol can decrease packet loss probability and increase throughput effectively comparing to the TDMA protocol without prediction.
