HIP-based handover mechanism under MIH architecture in heterogeneous wireless networks

Abstract

In this paper, we offers a HIP-based vertical handover scheme under MIH architecture in heterogeneous wireless network. Many diversity wireless access technologies are offering in Next Generation Wireless Networks (NGWN). In NGWN, the integration of wireless access network will be accomplished by seamless handover which contains many challenges i.e. service mobility, vertical handover, common authentication, unified accounting/billing, security mechanisms, QoS and service provisioning, etc. Toward this direction, our research aims to provide a complete integration of heterogeneous network architecture and support a fit mobility management for network to seamless handover. We focus on simulation about vertical handover execution for WiMAX to WiFi scenario. Our idea can modify defects of Mobile IP and SIP. And it provides internet users always best connection. Moreover, we hope to contribute our research to beyond 4G wireless networks.
