| 摘 要： | 详细说明了802.11e的EDCF中基于静态,AIFS与退避算法的三种机制的优先原理,理论上验证了EDCF对VoWLAN的QoS(服务质量)保证,通过建立VoWLAN软终端IBSS的仿真模型,比较了语音、视频和数据业务的性能,对不同负载的情况下就QoS性能指数(丢包率,延迟与抖动)进行了讨论.仿真结果表明EDCF对VoWLAN有一定的QoS保证. |

| Abstract: | The preference principles of EDCF in 802.11e based on Static-State,AIFS and the Backoff Algorithmare three Mechanisms are elaborated.EDCF guaranteeing to QoS(quality of service)of VoWLAN is confirmed theoretically.The performance of Audio,Video and data is compared through establishing Soft-Terminal simulation model in the IBSS of VoWLAN.The QoS performance parameters(Packet loss rate,Delay,Jitter) were discussed in different traffic loads.Simulation result shows that EDCF can provide the guarantee of QoS for VoWLAN |
| Keywords: | 802.11e EDCF VoWLAN QoS |
