Home/office intranet resource management for QoS-guaranteed realtime stream service provisioning on IEEE 802.11e WLAN

Abstract

Many broadband end user terminals in home/office networks are attached to IEEE 802.11 wireless LAN (WLAN) that provides the advantages of portability. In realtime multimedia service provisioning in WLAN-based on home/office intranet, however, it is essential to have an efficient QoS-guaranteed session management scheme between QAP and STAs. In this paper, we propose an efficient home/office intranet resource management scheme using Q-SIP/SDP for realtime stream service provisioning on IEEE 802.11e-based WLAN. For the QoS-guaranteed session allocation for realtime stream services (i.e., IPTV and VoIP), the proposed intranet resource management system exchanges control messages with Q-SIP(QoS Session Initiation Protocol) proxy server that communicates with QSTAs (QoS Stations), and controls the QAP (QoS access point) of IEEE 802.11e WLAN. The proposed Q-SIP/SDP session management scheme is also considered for DLS (Direct-Link Setup) for making QoS-guaranteed session between STAs located in same BSS (basic service set). The intranet management system is implemented using WBEM architecture, and provides resource discovery, WLAN channel allocation with CAC, and performance monitoring of each QBSS (QoS basic service set).
