Compared to end host mobility and multihoming with HIP existing HIPbased micro-mobility solutions have optimized handover performance by reducing location update delay. However all these mobility solutions are client-based mobility solutions. We observe that another fundamental issue with end host mobility and multihoming extension for HIP and HIP-based micro-mobility solutions is that handover delay can be excessive unless the support for network-based micro-mobility is strengthened. In this study we co-locate a new functional entity subnet-rendezvous server at the access routers to provide mobility to HIP host. We present the architectural elements of the framework and show through discussion and simulation results that our proposed scheme has achieved negligible handover latency and little packet loss. Keywords HIP mobility micro-mobility 1. Introduction Host mobility support is one of the key features of the next generation network which is the All-IP-based heterogeneous networks 1 . The duality problem of IP addresses 2 in simultaneously serving as both host identifier and locator in the Internet is the major issue that makes host mobility support challenging. During a communication session a mobile node MN may move within a single domain micro-mobility or move to a different domain macro-mobility 3 . These two main scenarios can be managed at different layers of the conventional TCP IP stack 4 . Access technologies can manage intra-link mobility L2 handoff
