基于IEEE802.16协议的VoIP服务质量调度算法

A Novel Algorithm Based on VoIP QoS in IEEE 802.16 Protocols

本文分析了VoIP的特点和IEEE802.16协议对服务质量(QoS)的定义。基于已有的无线城域网对VoIP的QoS控制策略,提出一种新型的调度算法。通过数学建模和仿真试验,证明了新算法对减小延迟和增加信道利用率方面效果显著。

This paper analyzes the characteristics of VoIP and the definitions of QoS in IEEE 802.16 protocols. We propose a novel scheduling algorithm based on traditional controlling strategy on the VoIP QoS in WMAN. By system model and simulation, this novel algorithm is proved to be efficient in reducing delay and increasing channel usage rate.
