802.11无线局域网链路层切换机制研究

Research on the Handoff Mechanism of 802.11 WLAN Link Layer

首先介绍了目前基于802.11无线局域网的各种切换算法,对其在切换延迟和丢包率等方面进行了分析。在此基础上提出了一种多点预先转发的切换模式,并对其切换原理和特征进行了阐述,另外也对其相关问题进行了说明。

This paper firstly introduces some handoff methods based on IEEE 802.11 and then analyzes their performance on handoff latency and packet-lost rate. Based on these methods, a handoff scheme based on multi-AP Forward is proposed and its handoff steps, features and related questions are also discussed.
