Mobility Management Schemes with Fast Handover in Integrated Wi-Fi and WiMAX networks

Abstract

The seamless internetworking among multiple heterogeneous networks is in demand to provide “always-on” connectivity services with QoS provision quality, anywhere, at any time. The hybrid networks of Wi-Fi and WiMAX networks can provide high data rate and enhanced multimedia services. In this paper, we discuss some handover issues and propose network architectures between Wi-Fi and WiMAX networks, a concept model of protocol stack and a two-tier mobility management scheme. Although this paper does not deal with detailed handover and QoS algorithms, We concentrate on mobility management mechanisms and investigate network architecture for supporting mobility management.
