Queue system with smart ARQ on Markov channel for energy efficiency

This paper is devoted to the analytical investigation of an ARQ scheme including the possibility to block the transmissions when the physical layer shows an error burst. The error model is taken by a two states Markov model. The ARQ is blocked when the channel is in fault because it makes not sense to continue to loose energy by attempting transmission over a non-reliable channel. Two different thresholds, one to block the transmission and one to restart it, are considered, and the performance in terms of average delivery packet number, average energy and average delay, are computed by means of an analytical approach. Some results are discussed and compared with simulations.
