Layer Manager-Based Wireless Overlay Model for Efficient Mobility Management in Next Generation Networks
نویسنده
چکیده
This paper proposes an architecture of multi-tier Wireless Overlay Network (WON) with Layer Manager (LM) for vertical handoff (VHO), switching and mobility management using Mobile IP protocol. It discusses the inter-layer mobility and Quality of Service (QoS) support in this architecture. Various functionalities of the Layer manager are implemented as modular blocks and are distributive over the gateways in each layer. The simulation results show that the proposed architecture supports smooth vertical handoff with acceptable handoff delay and call-drop probabilities.
