Moving Towards Mobile Third Generation Telecommunications Standards: The Good and Bad of the \u27Anytime/Anywhere\u27 Solutions

Mobile communication technologies are changing every aspect of the daily life, bringing new opportunities in many areas. Several converging mobile systems can potentially change organizations significantly by shifting the traditional boundaries of work-life and the workplace. Mobile telephony, combining satellite and terrestrial cellular systems, already transformed the way people work by allowing \u27anytime/anywhere\u27 telephone calling and text messaging. Broadband mobile telephony opens additional avenues to provide information conveniently as quickly and easily as possible, when needed and where needed. The evolution of wireless technologies (from Wireless Personal Area Networks to ubiquitous Third Generation/Universal Mobile Telecommunication System - UMTS) increased the number of services available to business organizations and mobile workers. Machine-to-machine, vertical applications, and mobile office applications are increasingly being deployed. Service providers and mobile operators are also changing the way they operate as a result of the increasing availability of mobile broadband communication services. IT departments need to change their systems, upgrade, and adapt their infrastructure and policies to support these mobile services. These changes are both positive and negative. With this progression, some fundamental questions related to privacy, security, and a new concept of work place and work space are raised. The implications for developing economies, such as China, and their potential for leapfrogging are future attention areas

Proximity-based systems: Incorporating mobility and scalability through proximity sensing

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.This thesis argues that the concept of spatial proximity offers a viable and practical option for the development of context-aware systems for highly mobile and dynamic environments. Such systems would overcome the shortcomings experienced by today’s location-based and infrastructure dependent systems whose ability to deliver context-awareness is prescribed by their infrastructure. The proposed architecture will also allow for scalable interaction as against the single level of interaction in existing systems which limits services to a particular sized area. The thesis examines the concept of spatial proximity and demonstrates how this concept can be exploited to take advantage of technological convergence to offer mobility and scalability to systems. It discusses the design of a proximity-based system that can deliver scalable context-aware services in highly mobile and dynamic environments. It explores the practical application of this novel design in a proximity-sensitive messaging application by creating a proof-of-concept prototype. The proof-of-concept prototype is used to evaluate the design as well as to elicit user views and expectations about a proximity-based approach. Together these provide a valuable insight into the applicability of the proximity-based approach for designing context-aware systems. The design and development work discussed in the thesis presents a Proximity-Sensitive System Architecture that can be adapted for a variety of proximity-sensitive services. This is illustrated by means of examples, including a variety of context-aware messaging applications. The thesis also raises issues for information delivery, resource sharing, and human-computer interaction. While the technological solution (proximity-based messaging) offered is only one among several that can be developed using this architecture, it offers the opportunity to stimulate ideas in the relatively new field of proximity and technological convergence research, and contributes to a better understanding of their potential role in offering context-aware services

A usage oriented analysis of vehicular networks: from technologies to applications

The research world is paying a lot of attention on vehicular networks nowadays. Novel vehicular services need a suitable communication channel in order to extend in-car capabilities and, generally, be aware about surrounding events. Such networks, however, present some special features, such as high mobility or specific topologies. These properties affect the performance of applications, and more effort should be directed to identify the necessities of the network. Few works deal with application requirements which should be considered when the vehicular network is designed. In this paper, we fill the gap, and propose an analysis of application requirements considering available technologies for the lower and network layer. This study contains key factors which must be taken into account not only at the designing stage of the vehicular services, but also when applications are evaluated.The authors would like to thank the Spanish Ministerio the Educación y Ciencia for sponsoring the research activities under the grant AP2005-1437, in frames of the FPU program

Personalization platform for multimodal ubiquitous computing applications

Dissertação para obtenção do Grau de Mestre em Engenharia InformáticaWe currently live surrounded by a myriad of computing devices running multiple applications. In general, the user experience on each of those scenarios is not adapted to each user’s specific needs, without personalization and integration across scenarios. Moreover, developers usually do not have the right tools to handle that in a standard and generic way. As such, a personalization platform may provide those tools. This kind of platform should be readily available to be used by any developer. Therefore, it must be developed to be available over the Internet. With the advances in IT infrastructure, it is now possible to develop reliable and scalable services running on abstract and virtualized platforms. Those are some of the advantages of cloud computing, which offers a model of utility computing where customers are able to dynamically allocate the resources they need and are charged accordingly. This work focuses on the creation of a cloud-based personalization platform built on a previously developed generic user modeling framework. It provides user profiling and context-awareness tools to third-party developers. A public display-based application was also developed. It provides useful information to students, teachers and others in a university campus as they are detected by Bluetooth scanning. It uses the personalization platform as the basis to select the most relevant information in each situation, while a mobile application was developed to be used as an input mechanism. A user study was conducted to assess the usefulness of the application and to validate some design choices. The results were mostly positive
