This specification defines extensions to the Proxy Mobile IPv6 protocol for allowing a mobile router in a Proxy Mobile IPv6 domain to obtain IP prefixes for its attached mobile networks using DHCPv6 prefix delegation. Network-based mobility management support is provided for those delegated IP prefixes just as it is provided for the mobile node’s home address. Even if the mobile router performs...

Mobile IPv6 has been proposed by the IETF (Internet Engineering Task Force) to be the solution to mobility management in IPv6 network. The work is now culminating to a standard status. But, one problem still remaining is the length of the handover time, which might cause packet loss. Thus the handover time should be as short as possible. Especially the real-time traffic suffers from packet loss...

This review presents current mobility extensions of IPv6 as designed to create a realtime compliant, secure mobile Internet. Starting from Mobile IPv6, the basic end-to-end mobility managment protocol, we discuss performace and security issues, as well as recent improvements to enhance mobility operations within the next generation Internet protocol.

Mobility management with provision of seamless handover is crucial for an efficient support of global roaming of mobile nodes (MNs) in next-generation wireless networks (NGWN). Mobile IPv6 (MIPv6) and its extensions were proposed by IETF for IP layer mobility management. Mobile IPv6 developed in 1997 is considered to be one of the key technologies for realizing mobile Internet which enables sea...

customized hardware system that is designed to perform dedicated software applications. Presently they are widely used in network equipment such as firewall, router, switch and so on. Now a day’s mobility of internet devices is increasing rapidly, but there are not enough IP addresses for mobile users, hence IPv6 is proposed to resolve this issue.IPv6 is the currently proposed standard for Inte...

Fast handover for Proxy Mobile IPv6 (FPMIPv6) can reduce handover delay and packet loss compared with Proxy Mobile IPv6 (PMIPv6). However, FPMIPv6 still cannot handle heterogeneous handovers due to the lack of unified Layer 2 triggering mechanism along with the booming of emerging wireless technologies. Media Independent Handover (MIH) can provide heterogeneous handover support, and a lot of in...

The project “AIRE 6 Wireless Access to IPv6 Networks” generated a hot spot of wireless Internet access using Wi-Fi (IEEE 802.11 b/g) in a native IPv6 environment. The setup of the project enables end-to-end connectivity using global public addresses. By incorporating mobility mechanisms of Mobile IPv6 (MIPv6), it allows scenarios always-on with mobility functions. Client connections are managed...

Fast IPv6 Address Configuration is pivotal to the unification of mobile Internet and mobile telephony services. We describe the standard method for IPv6 address configuration and examine its drawbacks, identify the current alternatives and their flaws and suggest two new methods of Duplicate Address Detection which perform Address Configuration more quickly.

Mobile IPv6 will be an integral part of the next generation Internet protocol. The importance of mobility in the Internet gets keep on increasing. Current specification of Mobile IPv6 does not provide proper support for reliability in the mobile network and there are other problems associated with it. In this paper, we propose “Virtual Private Network (VPN) based Home Agent Reliability Protocol...
