Abstract— Multi-hop relaying has attracted considerable attention recently as a key technique for improving cell coverage and throughput in wireless communication. We modelled various ARQ mechanisms that have been proposed for wireless multihop relay systems. To model the various mechanisms, we used a Discrete Time Markov Chain(DTMC) technique. We analyzed the performance of the ARQ mechanisms with respect to delay and throughput. We also validated the proposed ARQ model and the performance analysis by comparing the analysis with simulation results.
