Design of QoS and Admission Control for VoIP Services Over IEEE 802.11e WLANs
Supporting telephone services using wireless LAN as the access network is an emerging service. The SIP and IEEE 802.11e are perhaps the two most promising protocols to support such services. In this paper, we show how to integrate SIP and 802.11e to conduct call admission control and resource reservation to support VoIP’s QoS in IEEE 802.11e WLANs. Besides, we also suggest some adjustments and ...
متن کاملComparison of QoS Guarantee Techniques for VoIP over IEEE802.11 Wireless LAN
An emerging killer application for enterprise wireless LANs (WLANs) is voice over IP (VoIP) telephony, which promises to greatly improve the reachability and mobility of enterprise telephony service at low cost. None of the commercial IEEE 802.11 WLAN-based VoIP products can support more than ten G.729-quality voice conversations over a single IEEE 802.11b channel on real-world WLANs, even thou...

With both the enterprise and residential sectors embracing voice over IP (VoIP) at an accelerating pace, and the pervasive use of wireless local area networks (WLANs), the natural requirement emerged for a technology to support VoIP over WLANs without degradation of its quality of service (QoS). QoS requirements for WLANs are imposed also by video and multimedia applications tailored for use wi...
متن کاملSupporting VoIP Services in IEEE 802.11e WLANs
Voice over Internet Protocol (VoIP) over Wireless Local Area Network (WLAN) is becoming popular thanks to its cost efficiency. However, it has been a challenge to provide good quality of VoIP services in WLANs, which is due mainly to (i) the nature of contention-based channel access of WLAN Medium Access Control (MAC); (ii) the presence of coexisting non-real-time data traffic; and (iii) the ti...
متن کاملExtending End-to-End QoS to WiFi based WLAN
requirements on the network traffic compared to the traditional interactive and background applications. IEEE standard 802.11e addresses these QoS requirements in a WiFi based WLAN. It provides enhancements to the MAC layer protocol for supporting both prioritized and parameterized traffic between a QSTA and a QAP. To address the end-to-end QoS needs, the link level QoS supported by 802.11e sta...
