Performance Analysis for Polling Service in IEEE 802.16 Networks Under PMP Mode

In this paper, we focus on the polling mechanism adopted in IEEE 802.16 networks operating in PMP (Point-to- Multipoint) mode between the base station and the subscriber stations. We develop a queueing model for computing the performance of the polling service traffic, which takes into account the polling period amongst the various subscriber stations served by a single base station. Using our model, the waiting time distribution, the blocking probability, and other relevant performance measures are computed. The model can be used to investigate how the traffic in the polling service for each subscriber station can be allocated the necessary network resources to meet some certain Quality-of-Service (QoS) requirements.
