摘要

本文从提高系统工作效率的角度出发

提出了一种基于无争用集中控制的忙队列周期查询(BQPO)控制协议.该协议为时延QoS要求较高的无线终端提供了稳定可靠的保障

通过系统建模分析获得了系统的信息分组平均等待时间的解析结果.仿真实验结果表明理论分析和仿真实验的一致性与合理性

与PCF控制方式相比

BQPO协议具有更好的稳定性和时延QoS保障.

Abstract

To provide a more efficient wireless MAC protocol

Busy Queue Polled Only (BQPO) protocol

which is based on cyclic polling scheme

is presented.It can provide delay QoS and stability for the time-bounded services.The mathematical model of BQPO system and the mean value of message waiting time are explicitly obtained.The performance of BQPO is simulated and compared with PCF scheme.The results show that the simulation is in concordance with the theoretical analysis.The BQPO scheme can provide higher stability and better delay QoS than PCF scheme.
