Analysis of Queue Performance of GBN-ARQ and Its Improved Protocol Based on TDD Channel

Suoping Li, Jun Yu, and Yongkui Tie
Abstract— Considering Time Division Duplex (TDD) channel with susceptible environment and high packet error rate, this paper mainly analyzes delay performance of the data transmission system taking the n-copy GBN-ARQ protocol. First, combining the transmission characteristics of SR-ARQ based on nGBN-ARQ, we put forward an improved n-copy GBN-ARQ protocol which reduces the packet costs effectively. Next, we derive the mean delay indexes of the two systems by solving the M/G/1 queuing model with vacations according to the method of equivalent delay. We also discuss the effect of the delay performance affected by window length, packet error rate and copy number of the two systems in detail. The theoretical analysis and simulation indicate: the improved nGBN-ARQ protocol can still work normally when it is applied to the TDD wireless data transmission with high channel error rate and the improved nGBN-ARQ can cut down the packet cost and delay effectively, and improve the data transmission efficiency without changing the original arithmetic and increasing system complexity.

Index Terms— Queuing model, nGBN-ARQ, TDD, delay performance, equivalent service delay, mean packet delay.
