摘要：

In this paper we analyze the medium access control (MAC) of fixed WiMAX with respect to best effort (BE) traffic. WiMAX employs a contention based method with exponential backoff to facilitate multiple access. A two-dimensional Markov chain can be used to accurately model the backoff procedure. From this we derived expressions for channel access probability, access delay, system throughput and resource usage. The accuracy of the model and its results are validated by simulations carried out on an IEEE 802.16d simulator. Constraints and limitations of the model are also discussed. Insight from this model can be used to optimize bandwidth usage and channel partitioning.
