Mobility Management On The Next Generation Internet

In the recent years, Internet and mobile telecommunications develop rapidly and become popular and ubiquitous in our life. Besides, with the integration of their services, the boundary between mobile telecommunication networks and computer Internet networks is disappearing, which has resulted in a strong convergent trend towards the Internet as the uniform next generation networks for mobile as well as fixed networks. One of the key features of the next generation networks is mobility, namely it allows users to maintain services continuity while moving across the Internet. We call the next generation networks as the next generation mobile Internet. Hence, mobility management is an important issue in the area of the next generation mobile Internet.As Internet is the IP networks that operate based on the TCP/IP stack. The traditional Internet Protocol version 4 (IPv4) is the current IP layer protocol on the Internet, and the extension to Internet mobility support is called the Mobile IPv4 (MIPv4). However, it has only 32 bits for addressing on the Internet and seems not enough for the future increasing users. Besides, other disadvantages such as less security and Quality of Service (QoS) support will be problems in the future network environments. Therefore, a next generation IP protocol, i.e. the Internet Protocol version 6 (IPv6), has been developed by Internet Engineering Task Force (IETF) to replace the traditional IPv4. Moreover, IETF integrates the IPv6 with mobility support called Mobile IPv6 (MIPv6). Compared to the traditional MIPv4, the benefits in MIPv6 include the route advertisements for the movement detection, the stateless address auto-configuration and the inherent route optimization. This thesis focuses on improving the mobility management for the next generation mobile Internet over MIPv6 from the following aspects:Firstly, we discuss the current two routing mechanisms over MIPv6 (i.e. the bidirectional tunnelling and route optimization), analyze their advantages and disadvantages. In order to ensure that packets get routed to the current location more efficiently, we propose a new routing optimization approach. Compared with current other two mobility routing mechanisms, our approach not only can maintain the advantages of current routing mechanisms, but also avoid their disadvantages. Therefore, our approach can be use to replace current routing mechanisms and shows more efficiently in the universal scenario, where both communicating endpoints are in the foreign networks.Secondly, we focus on the handover management over MIPv6 including the movement detection, the CoA of Address (CoA) configuration and the binding update, and analyze the handover latency introduced by these handover procedures. In order to improve the handover...
