摘要

随着集中式无线局域网(WLAN)体系结构的出现，STA (station)有了向BSS (basic service set)过渡的需求。集中式WLAN架构是一种集中式分层网络，适合大规模部署。本文提出了一种基于簇链的上下文传输机制，以降低集中式WLAN架构中BSS的传输延迟。在BSS转换方面，与现有的上下文转移方案相比，所提出的机制具有(i)更低的上下文转移信令成本和(ii)更高的STA上下文命中率。

A Context Transfer Mechanism for IEEE 802.11r in the Centralized Wireless LAN Architecture

A station (STA) has the demand of the basic service set (BSS) transition in the emergence of centralized wireless LAN (WLAN)architecture. The centralized WLAN architecture is a centralized hierarchical network and is suitable for large scale deployment. In this paper, we propose a context transfer mechanism using cluster-chain to reduce the BSS transition delay in the centralized WLAN architecture. Comparing with the existing context transfer schemes in terms of BSS transition, the proposed mechanism can have (i) lower signaling cost for context transfer and (ii) higher hit rate in term of STA's context.
