- Abstract
For the low latency problem of channel access in aviation Ad Hoc network under high load, a multi-channel MAC protocol called PBLL/HL based on the priority and collaborative fairness is put forward. On the basis of statistical multi-channel detection, PBLL/HL optimizes the network traffic to ensure successful high priority data transmission with low latency by closuring the low priority data. It also lowers the latency of low priority data with PCA (Priority Threshold and Conflict Back-off Algorithm). The simulation results prove that PBLL/HL maintains an optimized network traffic by effectively controling channel access under high load, lowers the average access delay (Lowers the latency of low priority data more than 10% when the data overload), keeps the throughput steady under high load (Maximum throughput is 88.1%, the throughput falls flat when the data overload) and solves the problem of high latency and jam caused by high traffic in aviation data link.
