In this paper, the authors propose and evaluate an efficient multi-access protocol for cell-based wireless networks. The protocol addresses the problems in existing random-access protocols for wireless networks: long-term fairness as well as short term fairness in accessing a shared channel and the detection of hidden and exposed collisions. The proposed protocol is a limited contention protocol in which the set of contending mobiles are chosen based on a global common contention window maintained by every mobile station. The contention window is adjusted based on three possible channel states: no transmission, success, and collision.
