Mobility management for TCP connections has been discussed in literature since last several years. Many mobility management solutions have been proposed including end-to-end solutions and infrastructure dependent solutions. These solutions operate at different layers of TCP/IP protocol stack. End-to-end mobility management solutions have the advantage of not requiring the deployment of addition...

The mobility management issue in IP access networks can be dealt with from various perspectives. A possible approach includes the use of the Session Initiation Protocol (SIP) and its associate entities for mobility signaling. Following this approach, existing SIP functionality in a network can be reused for mobility management purposes, providing efficient utilization of resources. In this pape...

Mobility management is a key aspect to consider in future Internet architectures, as these architectures include a highly nomadic end-user which often relies on services provided by multi-access networks. In contrast, today’s mobility management solutions were designed having in mind simpler scenarios and requirements from the network and where roaming could often be taken care of with previous...

The concept of continuous assurance is not new, with a history spanning close to three decades in various guises. Recently there has been renewed attention in the area due to compliance imperatives, trends in governance and risk, anti-fraud measures and technological advances. However significant uncertainty surrounds the practicalities of how continuous assurance may be effectively implemented...

Firm assets are the most important element in strategy formulation and implementation. A company’s grounds to success can be found here. However, not all are equally important. Some will be considered strategic and others ordinary, depending on how influential they are when it comes to obtaining and appropriating rents, as well as how they hold up during a span of time. This will depend upon th...

The management of the mobility between radio networks composed of heterogeneous radio technologies, called inter-access mobility management, provides the capability to tie together heterogeneous radio networks into an integrated network. The 3GPP architectures with well-designed inter-access mobility management capabilities are a part of the solution to cope with the growth of the mobile data t...

The mobility management is a significant issue in 4G heterogeneous networks. However, the mobility needs to be managed by upper layer in the networks because of the limitation of mobility management at link layer. Session Initiation Protocol (SIP) supports personal mobility so that a user can be found independent of location and network device. But it cannot support IP mobility and cannot maint...

This paper proposes a novel automatic image registration method designed for urban scenes containing tall 3D objects under significant viewpoint changes. Our method is based on the fusion of two kinds of features: the interest regions and the edge groups, which we believe are more suitable than conventional local textures for such scenes. Many existing methods face matching difficulty either be...

Base IP mobility presents performance limitations when the mobile host increases its handoff rate between successive wireless points of attachment as a result of its mobility pattern. These limitations are augmented when latency externalities such as the round trip time between the MN and its peers, add to the total of latency and signalling overhead, impeding the performance of the mobility fu...
