Abstract:

he critical performance of air/ground data transmission precisely, on the basis of queue theory 

M/M/1 with priority, is analyzed. The dropping method according to living time and constructs 

the M/M/1/T model is introduced, and the scheduling algorithm is also researched. The 

calculation and simulation results show that, the new scheduling algorithm improves the system’s 

channel ratio, packet-passing ratio and latency.

Key words: priority, M/M/1/T, living time, age time, packet drooping
