Abstract :
We present a unified method to compute the exact performance of ARQ schemes for wireless networks. A wireless channel is modeled as a stochastic sequential machine. Accordingly, we propose a channel state ordered representation of the performance provided by an underlying block code. Based on proper events introduced to assess reliability, throughput, and delay performance of an ARQ scheme, we employ a discrete system model to obtain a matrix description for ARQ schemes used on wireless channels. Then, closed formulae are developed for all examined performance characteristics. Numerical results are given for a wireless ATM system
