A Proactive Resource Management in 3G Networks

Abstract

Providing quality of Service (QoS) over the 3G wireless networks such as the Universal Mobile Telecommunications System (UMTS) is one of the most active and challenging research area. 3G networks introduce IP services along with the traditional 2G phone system, and therefore represent an opportunity for real-time and multimedia applications such as the video conferencing. In this paper, we suggest a proactive QoS provisioning technique based on putting demands for network resources ahead of time as the mobile host moves from one cell to another. In this technique, the admission control algorithm prepares the mobile host's neighboring cells and therefore allowing real-time applications to move from one cell to another while maintaining and preserving its contracted QoS.
