Scalable Proxy Mobile IPv6 For Heterogeneous Wireless Networks

摘要

This work uses a cluster-based approach to provide scalability for Proxy Mobile IPv6 in large heterogeneous wireless network. We also propose an enhanced network-based IP-layer movement detection mechanism which allows the network to detect the attachment and the movement of each Mobile Node independently from the access technologies, without any special software support from Mobile Nodes. We implement these extensions on top of Mobile IPv6 for Linux (MIPL) v2.0. An evaluation of Proxy Mobile IPv6 in a cluster based Wireless Mesh Network is provided as a use case: we construct a virtual IPv6 Wireless Mesh Network using User-mode Linux (UML) ad Ns-2 Emulation and provide some early qualitative results to prove the correctness and the advantages of the proposals.
