This paper considers the performance of the polling based service classes of IEEE 802.16 based broadband wireless access networks and develops queueing models to evaluate their delay distributions and loss rates. Both single and multiple carriers OFDMA operations are considered and models are proposed for two polling strategies. The models can be used to provide probabilistic service guarantees and explore the impact of various system parameters on the performance, thereby aiding in system design. The models are verified using simulations.
