一种抖动窗口自适应的航空通信 MAC 协议 QoS 机制
A media access control protocol QoS mechanism based on adaptive jitter window in aeronautical networks
摘要
Abstract
According to the rigid demands of aeronautical communication for time-sensitive target attack,a media access control protocol with QoS is proposed.It provides differential services by adaptive adjustment of delay jitter window accord-ing to channel occupancy statistic.First,in packet queue stage,the queue length under steady-state conditions is derived from M/G/1 /K queuing theory.Second,in packet service stage,the average packet service time is obtained by modeling the adaptive sending delay jitter mechanism.Then,in packet propagation stage,the packet successful propagation proba-bility is acquired by modeling burst collision process.Finally,the mean delivery delay,successful transmission probabili-ty,system throughput are deduced and the principles of setting the max window are offered.The simulation results verify that it significantly increases the timeliness and reliability of high priority under heavy traffic load,so it can be applied to aviation communication network system with strict demand on timeliness and reliability.关键词
