摘要： 针对工作站到达两类对实时性要求不同的数据帧的应用系统，设计了一种实时的无线局域网介质访问协议。具有实时帧的工作站需要延迟一个较短的帧间隙时间，如果实时帧之间发生了传输冲突，接入点会轮询所有工作站以快速解决冲突。仿真结果表明实时帧比非实时帧经历更短的平均等待时间，并且等待时间具有确定的上限值。

Abstract: A real time wireless local area network (WLAN) media access protocol (MAC) is designed to deal with the applications which the stations have two classes of frame with different timing requirements. The station which has real time frame to send need defer a shorter inter frame space. If there happens a collision between real time frames, the access point will poll all the stations to solve this collision in time. Simulation results show the real time frames experience lower mean waiting times and can be transmitted in bounded times.

Key words: wireless LAN, media access protocol (MAC), frame class, upper bound
