Context-Aware Vertical Handover Management Architecture with QoS Provision in Heterogeneous Wireless Networks
2011
Handovermanagement with Quality of Service (QoS) provision is the major challenge for the seamless mobility across
heterogeneous wireless networks. In this paper, we propose the
context-awarevertical handoff (VHO) management architecture with QoS provision, based on the extension of
IEEE 802.21. In this proposed architecture, context information is collection from all layers of the
protocol stackboth mobile node side and network side as most as possible.
Context-awareAdaptive Analytic Hierarchy Process Method (CAAHP) method is chosen to identify the most suitable network for the optimization of
handoverdecision mechanism. For QoS provision, QoS Management Module is carefully designed to provide the various functionalities, especially, Dynamic QoS negotiation mechanism and Dynamic QoS Mapping mechanism to provide the QoS
service continuityand adaptation. Finally, the Mobile-initiated
Handoverscheme integrating with our proposed architecture is detailedly illustrated through the messages and procedures.
