An Traffic Intensity Based Media Access Control Protocol With Priorities

To improve the real-time performance of attacking time-sensitive targets, a MAC protocol based on traffic intensity is proposed. In this paper, the collision model of data packet is analyzed and the calculation formula of system throughput is given. Considering on the relationship between the traffic intensity of different data packets and network load, the threshold of each priority is reasonably set. Then the M/G/1 queuing model, with different customer rank and absolute priority, is applied to simplify and analyze the average queuing delay. Simulation results show the protocol achieves low latency for high priority, at the same time maintaining 97% success rate in the first chance. Meanwhile the performance of system throughput is improved.
