Strategies for dynamic management of the QoS of mobile users in wireless networks through software agents

Abstract

We propose an integrated solution for QoS management in mobile wireless networks that can be dynamically adapted to user requirements and resource availability. Due to the strong variability of the environment under examination, we propose to use mobile agents as the underlying enabling technology. We propose a proactive approach that tries to satisfy the user requirements by utilizing advance resource reservations, and a reactive approach which tries to negotiate network resources when significative changes in the demand of resources arise. We also propose a combination of the two approaches in an integrated hybrid system that combines a mobility predictive advanced bandwidth reservation scheme with a call admission control and resource reconfiguration strategy to support flexible QoS management.
