This paper discusses a wireless multiple access protocol for multimedia traffic called DMMA (Distributed control Multimedia Multiple Access). The protocol is used where a number of users dynamically migrate to/from an adhoc network to communicate multimedia messages. The protocol have four features. 1) Since the protocol doesn?t need a center station, it can construct an adhoc wireless network. 2) The protocol assigns a transmission slot periodically for real-time data, while for non-real-time data it assigns as many slots as possible to enhance efficiency. 3) The protocol uses a stable continual tree algorithm for slot reservation to reduce admission delay. 4) Every transmission data includes the control data indicating requiring slots successively, which enables a terminal to join and leave the network dynamically. The protocol is evaluated by simulation to show fair throughput for any multimedia data.
