Mobile IPv6 is a network-layer solution to node mobility for the IPv6 Internet. It allows a mobile node to maintain a continuous connection from one access point to another. MIPv6 introduces several security vulnerabilities such as the authentication and authorization of Binding Updates (BUs) during the home agent registration process. This paper deals with securing the standard mobile IPv6 han...

As the mobility and the number of affordable, powerful, and highly portable devices becoming networked increases, so will the amount of networked services offered, managed and discovered. In this paper, we discuss the need and use of service discovery mechanisms in future fixed and mobile networks. In particular, we choose to focus on future enterprise networks that we anticipate would need to ...

This paper presents an overview of IPv6-based mobility management protocols: mobile IPv6 (MIPv6), fast handovers for mobile IPv6 (FMIPv6), hierarchical mobile IPv6 (HMIPv6), and fast handover for hierarchical mobile IPv6 (F-HMIPv6). All these protocols play an important role in the next generation wireless networks, because in such networks, mobile users need to be freely change their access ne...

The Mobile IPv6 protocol is a major solution to supply mobility services on the Internet. Many networking vendors have already implemented it in their operating systems and equipments. Moreover, it was recently selected to provide permanent IP addresses to end-users of WiMAX and 3GPP2. Mobile IPv6 relies on a specific router called the home agent that hides location changes of the mobile nodes ...

It is a very important and to be worthy of research issue which elucidates that how to provide mobile users for roaming among different access technology networks through seamless handoff mechanism. IPv6 will play an important role in the future wireless access networks, each of equipment has its unique IP address. For mobile equipment, IPv6 have mobility support (Mobile IPv6). Therefore, in or...

This document specifies the operation of mobile computers using IPv6. Each mobile node is always identified by its home address, regardless of its current point of attachment to the Internet. While situated away from its home, a mobile node is also associated with a care-of address, which provides information about the mobile node’s current location. IPv6 packets addressed to a mobile node’s ho...

Mobile IPv6 has been designed by the IETF to provide mobility to the Internet. With mobility a user can move and change his point of attachment to the Internet without losing his network connections. If Mobile IPv6 was deployed on the Internet, typically Correspondent Nodes would be large servers of current content providers. These large servers have thousands of clients and in such scenario ma...

Hierarchical Mobile IPv6 introduces a new node called the Mobile Anchor Point (MAP) to improve the handover speed performance of Mobile IPv6 by reducing the amount of signaling in the ongoing connection between the mobile node, its correspondent nodes, and its home agent. With MAP as an additional node, it’s signaling, both received and sent is subject to several security vulnerabilities that n...
