Abstract :
We analyze the queueing performance of the go-back-N ARQ (GBN-ARQ) protocol in multi-rate wireless networks considering feedback delay. Multi-rate transmission is captured by a finite state Markov channel (FSMC) model for a slow Nakagami-m fading channel. The queueing problem is formulated as a G1/M/1 Markov chain where the exact queue length and delay statistics for the GBN-ARQ protocol can be obtained. We validate our analysis by simulations. The impacts of the system and channel parameters on the system performance are then investigated. The optimal partitioning of the signal to noise ratio (SNR) for different transmission modes are obtained so that the delay is minimized. The delay statistics obtained in this paper enables us to design wireless systems under statistical delay constraints and would be useful to predict the higher-layer protocol performance
