Mobility-incorporated dynamic and adaptive provisioning mechanism in differentiated service network

In this paper, we propose Mobility-incorporated Dynamic and Adaptive Provisioning mechanism (MDAP) which is path-level distributed admission control and resource management schemes for IP based Diffserv core network. Its goal is to guarantee predefined QoS metric regardless of user mobility maintaining high resource utilization. MDAP acts dynamically and adaptively as traffic situation and mobility patterns, in which especially utilizes global mobility behavior tendency of access domains. To guarantee QoS on the move, not only the mobility behavior tendency of the current access domain but also adjacent access domains´ are closely coupled with MDAP??s admission decision. And also MDAP dynamically manages resources based on the level of path utilization and in-out traffic rate of that path. By doing so, we can keep overall utilization high and QoS Degradation Probability (QDP) low at the same time.
