摘　　要：提出了一种应用于无线环境的ＡＴＭ多址控制协议动态帧长分组预约多址（ＤＦ－ＰＲＭＡ）．本协议利用动态帧长控制，可使系统能适应业务流量的变化，在不同业务条件下达到优化运行；并利用强制碰撞和保留时隙的方法，使系统的服务延时有了明确的保障，进而保障单个用户的服务质量（ＱｏＳ）和较高的信道利用率．This paper presents a new reservation based medium access control protocol dynamic frame packet reservation multiple access (DF-PRMA) - for wireless ATM network. The key features in the proposed protocol are the variable frame length and enforced collision, which allows for the optimal frame length dynamically adjusted according to the traffic load under the integrated service scenario and a limit on the delay performance. In particular, this approach allows for adaptability to the short term overload while under the light load, it can result in a shorter access delay, as opposed to the fixed frame length scheme. This Protocol can keep a high channel throughput and QoS.
