Discrete-time batch service \(GI/Geo/1/N\) queue with accessible and non-accessible batches (Q961469)

Summary: Discrete-time queues are extensively used in modelling the asynchronous transfer mode environment at cell level. In this paper, we consider a discrete-time single-server finite-buffer queue with general inter-arrival and geometric service times where the services are performed in accessible or non-accessible batches of maximum size b with a minimum threshold value a. We provide a recursive method, using the supplementary variable technique and treating the remaining inter-arrival time as the supplementary variable, to develop the steady-state queue/system length distributions at pre-arrival and arbitrary epochs under the early arrival system. The method is depicted analytically for geometrical and deterministic inter-arrival time distributions, respectively. Various performance measures and outside observer's observation epochs are also discussed. Finally, some computational results have been presented.
