摘　　要：论文根据IEEE802.11PCF协议轮询机制的实时特性,以基本业务群(BSS)内站点(STA)的分组数为基础,提出了一种基于优先级的动态轮询协议。阐述了该协议的基本结构以及实现算法,并对协议性能进行分析。同时也给出了计算机仿真结果,实现了对原有轮询机制性能的改善。IEEE802.11PCF protocol is based on polling mechanism and supports multimedia applications.This paper proposes a dynamic polling protocol according to priority which is distributed according to the quantity of packets in a STA in the BSS based on this character,and introduces the construction and algorithms of the protocol.The simulation results show that this schedule can improve the capacity of system.
