WIMAX的主要问题之一是多个竞争访问的用户共享介质。各种随机接入机制，如ALOHA及其相应的变化已经被广泛研究，作为协调竞争用户之间的媒体接入的有效方法。在本文中，时隙ALOHA协议实现为一个两状态系统。使用马尔可夫模型，我们评估的信道利用率，我们分析了吞吐量在不同的公平性条件下。考虑了合作团队问题。
One of the main problems in WIMAX is to share the medium by multiple users who compete for access. Various random access mechanisms, such as ALOHA and its corresponding variations have been widely studied as efficient methods to coordinate the medium access among competing users. In this paper the slotted ALOHA protocol is implemented as a two-state system. Using Markov Models, we evaluate the channel utilization and we analyze the throughput under different fairness conditions. The cooperative team problem is considered.
