WLC22-1: Queueing Performance Analysis of Periodic Polling Services for VoIP in an IEEE802.16 System

In this paper, we consider the queueing performance of periodic polling services for VoIP in an IEEE802.16 system, which is modeled by an MIGIC type queue with periodic batch service. We carry out an analysis for this system, using a generating function approach with supplementary variable technique. As a service discipline, the size of batch, the transmission duration in units of frames, i.e., contiguous frames, and the vacation period correspond to the bandwidth assigned to a subscriber station and the period to poll other subscriber stations, respectively. In numerical examples, the mean queue lengths are given, according to various system parameters.
