In this paper, we study the collision resolution protocol of the IEEE 802.16 standard for metropolitan broadband wireless access systems. The standard specifies the use of a random access scheme based on the slotted binary exponential backoff (BEB) algorithm during the bandwidth request phase. We follow a team problem approach towards the analysis of the throughput and the delay during the bandwidth reservation process. A Markov chain analysis is used to obtain the optimal retransmission probabilities, the optimal value of the initial backoff window size, Wmin, maximizing the throughput and the expected delays experienced by a subscriber station (SS) when placing its bandwidth requests.
