A New Method of Very High Frequency Channel Access Protocol Analysis

ZHANG Jun,FANG Xin,PAN Lei,ZHANG Qi shan(Beijing University of Aeronautics and Astronautics,Beijing 100083,China)  
A new method of VHF channel access protocol analysis based on semi Markov model is presented in this paper.A model of channel access state transition for air ground datalink is established.By introducing the state mean holding times(HT) and state transition probabilities (TP) into this model,the presentation of the safe state probability and the number of busy users is obtained,which is a new way for property analysis and evaluation of channel access protocol.By using this approach,system parameters are not restricted to an exponential distribution,which is close to the practical situation.The method has been applied into VHF datalink system and the simulation results show that it is effective.
