Queuing system M/M/1/T with priority dropping packets mechanism based on living time

Abstract

The abstract should summarize the contents of the paper and should contain at least 70 and at most 150 words. It should be set in 9-point font size and should be inset 1.0 cm from the right and left margins. There should be two blank (10-point) lines before and after the abstract. This document is in the required format. The standard queuing system M/M/1/N with dropping packets mechanism is based on queue length, which is not an ideal model for air/ground data transmission. On the basis of queue theory M/M/1 with priority, the dropping method is proposed according to living time and constructs the M/M/1/T model to improve the scheduling algorithm on the performances of the system's channel ratio, packet-passing ratio and latency. © 2011 Springer-Verlag.
