With the recent advances in portable devices and wireless networks, a new paradigm of computing has emerged which is known as mobile computing. In general mobile computing can be seen as an integration of portable device and networks that support mobility, providing anytime, anywhere communication. IP mobility allows seamlessly mobility between different access networks and technologies. Mobile...

Mobile IPv6 allows a Mobile Node to remain reachable by a Correspondent Node while roaming from one network to another network. In Mobile IPv6, a Mobile Node directly updates its current location information to a Correspondent Node using a route optimization method. Route optimization helps to culminate the packet delay incurred due to suboptimal route traversed by the packets from a Correspond...

Traditional work turning around mobility support has usually focused on host mobility, i.e. single terminals which change their point of attachment in the Internet topology, whereas the most current type of mobility in IPv6 is probably going to be network mobility, i.e. entire IPv6 networks which border routers change their point of attachment to the Internet topology. Mobile networks are expec...

Internet Protocol Version 6 (IPv6), also called the Next Generation Internet Protocol (IPng) is a natural increment to IPv4. IPv4 was never intended for the Internet that we have today, commonly used in mobile and distributed environments, either in terms of customer requirements or security concers. The changes from IPv4 to IPv6 include primarily expanded addressing capabilities, the header fo...

The IETF Mobile IPv6 protocol provides a mobility management scheme for the Internet. Mobile IPv6 handles macro-mobility and micro-mobility identically. We believe that a hierarchical scheme that separates micro-mobility from macromobility is preferable since it would be more scalable. In this paper, we present a mobility management architecture that makes use of the IPv6 Address format hierarc...

The last decades have brought tremendous improvement in wireless internet and its technologies. This has inspired the development of a variety of new services in business and consumer markets. The real time applications such as voice over internet protocol (VOIP) and other multimedia traffic such as Internet Protocol television have driven the demand for increasing and guaranteed bandwidth requ...

IP-based mobility management is considered as core technology in the next generation network environment since the core network is moving toward all IP network and IPbased wireless LANs are blooming. Mobile IPv6 is developed to support mobility in global network, and Hierarchical Mobile IPv6 is being considered as a local mobility management protocol to reduce signaling overhead for mobility ma...

This paper identifies the issues in internetworking of Wireless ATM with Mobile IPv6. The mobility features of both Wireless ATM and Mobile IPv6 are exploited to achieve efficient interworking. We define the necessary protocol signaling for Mobile IP–ATM interworking mobility management procedures.

Just as the Advanced Sockets API for IPv6 gives access to various extension headers and the ICMPv6 protocol, this document specifies the same level of access for Mobile IPv6 components. It specifies a mechanism for applications to retrieve and set information for Mobility Header messages, Home Address destination options, and Routing Header Type 2 extension headers. It also specifies the common...
