This paper presents the mathematical analysis of the truncated binary exponential backoff (TBEB) mechanism as a contention
resolution for bandwidth requests in the broadcast polling and the
multicast polling in the IEEE 802.16e. We derive the delay
distribution and the loss probability of request packets in the TBEB
over Gilbert-Elliot error channel, by analytic methods on the
assumption of Bernoulli arrival process and the unsaturated
condition. The optimal contention period of transmission
opportunities for transmitting bandwidth requests can be obtained
while satisfying QoS on delay bound and loss bound. Furthermore, we
find the utilization of transmission opportunity to see efficiency
of the bandwidth. Numerical examples show that the analytical
results are well-matched with simulations, and the performance
evaluations in the broadcast polling and multicast polling are
compared on the mean delay, the loss probability and the utilization
of transmission opportunity. Numerical results address that the
multicast polling with more groups has better performance than the
broadcast polling in the sense of shorter delay, lower loss
probability and higher utilization of transmission opportunity.
