QoS Provisioning in Wireless Networks

by unknown authors
"... Abstract The importance of mobile connectivity along with the popularity of the Internet is fueling the demand for wireless networks to bring diverse applications from the wired network to mobile users. This poses a challenge for wireless networks to provide different, but yet consistent and predict ..."

and predictable, grades of Quality of Service (QoS) over the wireless media. Wireless scheduling determines how efficiently the wireless channel will be shared amongst contending users and is an integral component of wireless QoS provisioning. Although wireline scheduling that offers QoS guarantees are abundant

Provisioning

by Chien-liang Fok, Gruia-catalin Roman, Chenyang Lu
"... Heterogeneous wireless sensor networks represent a challenging programming environment. Servilla addresses this by offering a new middleware framework that provides service provisioning. Using Servilla, developers can construct platform-independent applications over a dynamic set of devices with div ..."

Abstract An integrated energy aware wireless transmission system for QoS provisioning in wireless sensor network

by Yong Yuan A, Zongkai Yang A, Zhihai He B, Jianhua He A , 2005
"... A significant amount of research efforts have been done to improve the energy efficiency of wireless sensor network (WSN). However, not much has been done to optimize the Quality of Services (QoS) of WSN. Actually, energy efficiency should be jointly optimized with QoS to make WSN useful. In this pa ..."

to be implemented in integrated network architecture (UMTS, WiMAX and WLAN). The aim of our novel framework is presenting a new module that shall provide the best QoS provisioning and secure communication for a given service using one or more wireless technologies in a given time.

Cross-layer resource allocation over wireless relay networks for quality of service provisioning

by Jia Tang, Xi Zhang - IEEE JOURNAL ON SELECTED AREAS IN COMMUNICATIONS , 2007
"... We propose a physical-datalink cross-layer resource allocation scheme over wireless relay networks for quality-ofservice (QoS) guarantees. By integrating information theory with the concept of effective capacity, our proposed scheme aims at maximizing the relay network throughput subject to a given ..."
