Abstract Localized mobility management is a well-understood concept in the IETF, with a number of solutions already available. This document looks at the principal shortcomings of the existing solutions, all of which involve...

With the convergence of the Internet and the mobile communications world, Internet-based services may become available on any user device. In order to make efficient use of such a ubiquitous environment the user demands to access his personalized services from any place, anytime and on any device regardless of the type of access network. In particular, we consider the situation that a user tran...

A multi-layer mobility management architecture has been designed to take care of real-time and non-real-time traffic for intra-domain and inter-domain mobility in a survivable network. It consists of three components based on functionality. SIP based mobility management is used for real-time communication, and MIP-LR is used for non-real-time communication when nodes move between two different ...

Mobility is a characteristic that can be applied to software which allows it to move between machines. However, since this in itself is such a broad definition, it is important to note that the movement of programs is fundamentally different to the movement of executing software; the former being primarily a data transfer operation and the latter involving capturing some notion of the state of ...

Systems Optimization for Mobility Management Ashutosh Dutta Wireless network mobility frees the user from location dependence but requires additional mechanism to preserve network connectivity. Mobility events occur when user movement causes one network connection to be replaced by another. A network connection has associated with it properties, for example, network attachment points, network i...

This paper provides a novel home-proxy based framework which integrates the mobility management and QoS management techniques that have been adopted in the Internet environment. It then combines a mobility prediction and resource pre-allocation scheme with the above home-proxy based framework to provide an efficient mobility management environment capable of supporting real-time services. The v...

in cognitive radio (CR), CR users or also known as secondary users (SUs) are considered licensed spectrum. During the case when the primary user claims the band of the spectrum that is occupied by the SU ongoing call must be transferred to another unused spectrum band. The variation in spectrum band is called spectrum mobility. In this paper, we investigate an analytical model to show the effec...

Mobility Management functionality in the Plug-and-Play (PaP) architecture is presented comprising different approaches for Actor, Terminal, User and Session Mobility Management. We explore a few issues related to implementation design and propose a set of components to facilitate the deployment of this platform in the available PaP applications. The PaP architecture is briefly introduced and su...

Next Generation Networks are becoming more and more converged. Like the System Architecture Evolution (SAE) which encourages Fixed Mobile Convergence. It is a packet switched network which connects different radio access technologies. With this heterogeneity, mobility management becomes an issue as the goal is to always achieve seamless mobility. However, various access technologies support dif...
