摘要：
In order to guarantee that a mobile station without mesh function can still keep a high transmission rate while it moves fast between wireless access points in the wireless mesh network (WMN), a layer two (L2) fast transition scheme based on 802.11s WMN was proposed. This scheme employs the idea of cross-layer design, and the whole transition process is implemented at L2. It considers the information both from LLC (logic link control) sub-layer and from MAC (medium access control) sub-layer, combines and improves the related 802.11s schemes to greatly raise the efficiency of the transition. The simulation results show that compared with the transition scheme defined in the 802.11s draft, the fast transition scheme can decrease the transition delay by 2 to 4 times and the number of packet drop by 2 to 8 times.
