Performance Evaluation of ARQ Schemes for Service-Oriented Internet in Wireless Networks

In this paper, we analyze the performance of automatic repeat request (ARQ) schemes for the service-oriented Internet in wireless networks. Considering the self-similar nature of a massive-scale multimedia service shown in Internet traffic, in this paper we present a discrete-time system operating on the basis of time slotting with a batch arrival. Moreover, taking into account the delay in the setting up procedure of the channels, we introduce a setup strategy in this system model. In the performance analysis, firstly, by using an imbedded Markov chain, we derive the probability generation functions (P.G.Fs.) of the queueing length, the waiting time and the busy period of the system. Then, we use these analyses to give some important performance measurements for wireless networks using ARQ schemes in terms of the response time and the setup ratio for the self-similar traffic. In numerical results, we make some comparisons such as the response time and the setup ratio with the systems by using other previously known ARQ schemes having the memoryless traffic to show the influence of the self-similar degree on the system performance.
