Providing service guarantee in 802.11e EDCA WLANs with legacy stations
Although the EDCA access mechanism of the 802.11e standard supports legacy DCF stations, the presence of DCF stations in the WLAN jeopardizes the provisioning of the service guarantees committed to the EDCA stations. The reason is that DCF stations compete with Contention Windows (CW ’s) that are predefined and cannot be modified, and as a result the impact of the DCF stations on the service re...
متن کاملFlow-level QoS guarantees in IEEE 802.11e-EDCA based WLANs
Wireless LANs provide a broadband and mobile access to Internet, allowing multimedia mobile services to become a reality by using an alternative network to actual cellular systems. Simultaneously, the Internet user behavior is evolving to include VoIP and P2P services to the already traditional Web browsing, file transfer or e-mail. However, in this scenario, WLANs show several performance limi...
متن کاملAn enhancement to the IEEE 802.11e EDCA providing QoS guarantees
One of the challenges that must be overcome to realize the practical benefits of ad hoc networks is quality of service (QoS). However, the IEEE 802.11 standard, which undeniably is the most widespread wireless technology of choice for WLANs and ad hoc networks, does not address this issue. In order to support applications with QoS requirements, the upcoming IEEE 802.11e standard enhances the or...
متن کاملA scalable service architecture for providing strong service guarantees
For the past decade, a lot of Internet research has been devoted to providing different levels of service to applications. Initial proposals for service differentiation provided strong service guarantees, with strict bounds on delays, loss rates, and throughput, but required high overhead in terms of computational complexity and memory, both of which raise scalability concerns. Recently, the in...
متن کاملInformation Society Technologies (ist) 6th Framework Programme Deliverable Reference Number: D-ia-8.3-7 Deliverable Title: Proceedings of the Third Workshop on Wireless and Mobility Project Co-funded by European Commission within the Sixth Framework Programme (2002-2006)
As the use of WLANs based on IEEE 802.11 increase, the need for QoS becomes more obvious. The upcoming IEEE 802.11e aims at providing QoS, but its contention-based medium access mechanism, enhanced distributed channel access (EDCA), provides only service differentiation. In order to provide QoS guarantees, we have proposed an extension called EDCA with resource reservation (EDCA/RR), which enha...
