Performance enhancements of combining QoS provisioning and location management in wireless cellular networks

Abstraci Quality of service (QoS) provisioning and location management (LM) in celldar networks are solved separately in previous work. For realistic network environments, we have propoaed a framework of combining QoS provisioning and LM by nsing all available user mobility information. In this paper, we present performance evalmations to show that this framework can yield more elcient solutions for both. We propose a novel path-based LM scheme in this combined framework and evalmate the performance gain of the new scheme over the original path-based LM scheme by simulations. Further, we propose a new connection admission control (CAC) acheme derived from this combined framework for QoS provisioning and present results showing performance enhancements over CAC schemes proposed previonsly.
