Wireless LAN Service Quality Optimization in Academic Environments

Quality of Service in Wireless LAN

In this paper a wireless system for IP with QoS is presented. An interface between IP and the wireless sub-system for QoS mapping is suggested. The approach is guided by solutions known from ATM networks and service differentiation in IP networks. Next to the service mapping the wireless MAC scheme has a decisive impact on QoS provisioning. An appropriate scheme that has been developed for the ...

IEEE 802.11e Wireless LAN for Quality of Service

In this paper, a comprehensive overview of the new features of an upcoming new standard IEEE 802.11e to support Quality of Service (QoS) in Wireless Local Area Networks (WLANs) is presented. We address Medium Access Control (MAC) enhancements found in the current 802.11e draft specification by emphasizing the differences from the legacy 802.11 standard. New mechanisms for QoS support, namely En...

Revamping Quality of Service of Video Streaming over Wireless Lan

Just like video streaming over a wired network, streaming can also be done over a wireless LAN. However, real-time streaming over wireless networks is a challenging proposition due to the highly variable nature of wireless links and the resource-poor nature of mobile devices. In such a context, transmission control schemes have to dynamically adapt both to the application requirements and the c...

Suitability study of Differentiated Service for Quality of Service in wireless LAN

We analyse the behaviour of data and streaming transmissions in wireless networks. We propose to use a modified access point with Quality of Service features. It is expected that the modification will improve transmission terms for multimedia streams.
