Wireless of IP Network: Mobility Management: Advancing from Mobile IP to HIP-based Network
2008 PhD Thesis, School of Electrical and Computer Engineering, RMIT University
Wireless networking introduces a whole range of challenges to the traditional TCP/IP network. In particular, IP address the issue of overloading because IP addresses are used as a network locator and an end point identity in the different layers in an OSI model. Even though Mobile IP is widely deployed, it has significant problems relating to performance and security. The Host Identity Protocol (HIP) provides secure mobility management by solving the IP address overloading from another angle. It restructures the TCP/IP model and introduces a new layer and a new namespace. The performance of HIP has proven to be better than Mobile IP and also opens a range of new research opportunities. This dissertation proposes and analyses a new step-stone solution from the Mobile IP-based network into a HIP-based network. The main advantage of this new solution is that much less change is required to the operating system kernel of the end point compared to a full HIP implementation. The new step-stone solution allows Mobile IP to use some HIP features to provide better security and handover performance. This dissertation also proposes several new and novel HIP-based wireless communication network architectures. An HIP-based heterogeneous wireless network architecture and handover scheme has been proposed and analysed. These schemes limit the HIP signalling in the wireless network if no communication to external networks is needed. Beside the network architecture modification, the hybrid Session Initial Protocol (SIP) and HIP-based Voice over IP (VoIP) scheme is proposed and analysed. This novel scheme improves the handover latency and security. This dissertation also proposes and analyses a new and novel extension to HIP, a HIP-based micro-mobility management, micro-HIP (mHIP). mHIP provides a new secure framework for micro-mobility management. It is a more complete HIP-based micro-mobility solution than any other proposed in existing studies. mHIP improves the intra-domain….
