Abstract

Aiming at the QoS problems of QoS and channel access in aviation Ad Hoc network under high load. A multi-channel MAC protocol(DQM)based on the dynamic QoS is put forward. On the basis of statistical multi-channel detection, DQM optimizes the network traffic to ensure high priority data transmit successfully with low latency by closuring the low priority data. Aiming at ensuring the access rate of high priority data, it utilizes the flow prediction model to predict the network flow and uses the PSO to find the most optimal priority threshold .The simulation results prove that DQM maintains an optimized network traffic by adaptively controlling channel access under high load, ensures the access rate of high priority data more than 99% and solve the QoS and latency problem caused by high traffic in aviation data link.
