The use of unscheduled contention based channel access protocols in mobile ad hoc networks is very attractive due to their transparency to toplolgical change, relatively low overhead, and ease of implementation. Recent reports [1], however, have shown that the wodely available asynchronous contention based 802.11 protocol has significant fairness issues especially with regard to exposed terminals. These fairness issues are a direct result of the asynchronous nature of the protocol. In this paper, we present the Synchronous Unscheduled Multiple Access protocol which has all the benefits of a contention based access protocol while insuring fair access to all nodes
