Abstract: Mobility management with QoS (Quality of Service) support is a major requirement for the success of next generation wireless networks. With this goal in mind, this paper proposes a new architecture that integrates Mobile WiMAX (WorldWide Interoperability for Microwave Access) with MIP (Mobile IP) and MPLS (Multiprotocol Label Switching) protocols as well as a mobility prediction algorithm to enable seamless handover. The anticipated handover technique provides service continuity based on information about the MN|s (Mobile Node) location and speed, as well as the BS|s (Base Station) signal strength. The proposed architecture is also enhanced from the traffic engineering mechanisms provided by the MPLS protocol.
