The Airborne Communications Node (ACN) platform supports many communications services, including IP-based data services. Mobility management is needed to ensure that packet delivery operates properly in the presence of mobility, and that smooth handoffs occur between points of attachment to the network. In this paper, IP mobility management mechanisms are explained and a network architecture to...

The convergence of the existing network access technologies to a common IP-based architecture and the increase in popularity of accessing video content over the Internet makes IPTV a promising solution for media and entertainment industries. Additionally, video content delivery to the increasingly popular mobile devices over heterogeneous wireless networks makes IPTV even more appealing. Howeve...

The raise of demanding multimedia content and the increasing number of mobile devices originated a rapid growth of mobile Internet traffic, which is expected to continue increasing with an exponential behavior in the next years. In order to cope with this rapid increase, service providers are already developing new strategies, such as the selective traffic offloading through the wireless local ...

This document defines the requirements for Distributed Mobility Management (DMM) at the network layer. The hierarchical structure in traditional wireless networks has led primarily to centrally deployed mobility anchors. As some wireless networks are evolving away from the hierarchical structure, it can be useful to have a distributed model for mobility management in which traffic does not need...

Mobility of a phone within a cellular network or of a computer within the Internet has to be managed by the respective network infrastructure: Routes to and from a mobile device have to be changed. In order to base mobility management of future cellular networks on IP, the Internet Protocol, various proposals like Mobile IP are currently being discussed. In this paper, we develop a simple model...

Over the past 25 years, the evolution of the internet and the advances of wireless technologies have made a tremendous impact on lifestyle of people around the world. Together, these two factors have changed the way people communicate, work, and get their entertainment. In order to be always best connected for various applications, the network selection procedure in heterogeneous multi-access e...

A hierarchical IP-based mobility management mechanism is proposed for VoIP applications. The suggested mechanism uses the DMA architecture, based on IDMP, for managing intra-domain mobility and SIP’s dynamic binding mechanism for managing global mobility. This combination of network and application layer mobility management reduces the global signaling load, provides fast handoff for ongoing co...

This paper presents the concept of role mobility and the value of role mobility in an open service environment. We outline the aspects of role management and role mobility and we describe an open, reusable component for role management. Then, we show how this component can be deployed in a TINA environment with a minimum number of changes to the TINA service architecture.

This document discusses security threats to network-based localized mobility management. Threats may occur on two interfaces: the interface between a localized mobility anchor and a mobile access gateway, as well as the interface between a mobile access gateway and a mobile node. Threats to the former interface impact the localized mobility management protocol itself.

Next Generation Networks (NGN) has a major impact on existing communication technology. The main goal of Next Generation Networks is to give a greater flexibility to the users to access the desired services from the available heterogeneous networks at anytime, anywhere vigorously with the concept of generalized mobility. Mobility management is one of the crucial functions in NGN. It is very muc...
