A hierarchical agent assisted MIPv6 handover scheme with QoS support

Abstract

This paper proposes a hierarchical mobility management architecture providing adaptive QoS control to improve the performance during mobile handovers, especially break-before-make handovers. In the proposed scheme, the information for QoS configuration and location management is carried by the same set of messages. The interactions between the QoS Agents (QA) enable smooth handover, with better performance in terms of IP layer handover latency and QoS configuration latency when the MN is away from the home network.
