摘要

IEEE 802.11无线网络已经引起了无线服务提供商的注意，并被广泛部署在机场、酒店和大学校园等公共场所，用于提供互联网接入和实时服务。我们提出并实现了一种实用的切换技术，旨在将切换延迟减少到小于10ms。通过将扫描与切换执行过程解耦，减少了切换延迟。并对该方案在商用VoIP客户端Skype上的效果进行了评价。本文还研究了所提出的切换和优化后的背景扫描对音频和视频流的影响。结果表明，所提出的切换方案对多媒体VoIP和音视频流流量的影响最小，具有良好的多媒体性能。

Multimedia Ready Handoff Technique for 802.11 Networks

IEEE 802.11 wireless networks have caught the fancy of wireless service providers and are being very commonly deployed for providing internet access and real time services at public places like airports, hotels and university campuses. We have proposed and implemented a practical handoff technique aimed at reducing handoff latency to less than 10ms. Handoff latency has been reduced by decoupling scanning from handoff execution process. Effect of the proposed scheme on commercial VoIP client, Skype has been evaluated. Effect of the proposed handoff and optimized Background Scan on audio and video streaming has also been investigated. Results show that the proposed handoff scheme casts minimal effect on multimedia VoIP and audio/video streaming traffic and is multimedia ready.
