- PublicationEmbedded agents: a paradigm for mobile services(Inderscience, 2006-01)
; ; ; Mobile computing radically challenges some of the traditional assumptions associated with the software development lifecycle, and end-user behaviour. Successfully meeting these challenges is of fundamental importance if mobile computing is to fulfil its considerable potential. One approach to this concerns the prudent and selective adoption of intelligent techniques. However, reconciling the conflicting demands of deploying sophisticated resource-intensive computational algorithms on devices that are inherently resource-poor raises significant difficulties. Recent developments in intelligent agent technologies offer one viable approach to resolving this conflict. This paper explores the state-of-the-art in mobile computing and intelligent agents. In particular, issues pertinent to the deployment of agents on mobile devices are considered in detail. To illuminate this discussion, the implementation of one such framework is described720Scopus© Citations 26 - PublicationMobile multimedia : reflecting on dynamic service provisionDelivering multimedia services to roaming subscribers raises significant challenges for content providers. There are a number of reasons for this; however,the principal difficulties arise from the inherent differences between the nature of mobile computing usage, and that of its static counterpart. The harnessing of appropriate contextual elements pertaining to a mobile subscriber at any given time offers significant opportunities for enhancing and customising service delivery. Dynamic content provision is a case in point. The versatile nature of the mobile subscriber offers opportunities for the delivery of content that is most appropriate to the subscriber's prevailing context, and hence is most likely to be welcomed. To succeed in this endeavour requires an innate understanding of the technologies, the mobile usage paradigm and the application domain in question, such that conflicting demands may be reconciled to the subscriber's benefit. In this paper, multimedia-augmented service provision for mobile subscribers is considered in light of the availability of contextual information. In particular, context-aware pre-caching is advocated as a means of maximising the possibilities for delivering context-aware services to mobile subscribers in scenarios of dynamic contexts.

Too often, however, this endeavour is hindered by the poor data rates supported by wireless telecommunications networks and by the limited computational resources available on mobile devices. We describe an approach to overcome these limitations, which is based on extremely dynamic and proactive precaching. This approach, which we have termed intelligent precaching, is realised through the innovative deployment of intelligent agents on mobile devices. To illustrate this concept, the design and implementation of an archetypical mobile computing application is provided, namely that of an electronic tourist guide. This is augmented with a description of the salient points derived from a user evaluation, from which emerging avenues for further research are identified.

; ; ; Mobile computing is undoubtedly one of the predominant computer usage paradigms in operation today. The implications of what might be cautiously termed a usage paradigm shift have still not crystallised fully, either for society, or those envisaging a new raft of applications and services for mobile users. However, fundamental to the current and future success of mobile computing are mobile telecommunications networks. Such networks have been a success story in their own right in recent years, both as traditional voice carriers and, increasingly importantly, as a conduit of mobile data. The potential for new mobile data applications is immense, but, crucially, this potential is severely compromised by two factors inherent in mobile computing: limited bandwidth and computationally restricted devices. Hence, the academic and commercial interest in harnessing intelligent techniques as a means of mitigating these concerns, and ensuring the user experience is a satisfactory one. In this paper, the broad area of intelligence in telecommunications networks is examined, and issues relating to the deployment of intelligent technologies are explored. In particular, the potential of intelligent agents is identified as a viable mechanism for realising a full end-to-end deployment of intelligence throughout the network, including possibly the most crucial component: the end user's device. As an illustration of the viability of this approach, a brief description of a mobile blogging application is presented.1840Scopus© Citations 13 - PublicationExploiting multi-agent systems in realizing adaptivity in the mobile tourist domain(IOS Press, 2009-04)
; ; ; Ongoing developments in an array of mobile computing technologies have rendered the deployment of intelligent agents feasible on lightweight computational devices such as mobile phones. This development extends the Multi-Agent System (MAS) paradigm to a new frontier, opening up significant avenues of research in intelligent mobile computing, amongst others. To demonstrate the potential of this approach, the practical realization of adaptivity in two classic agent-based mobile computing applications is considered. Though focusing on the tourist domain, it is contended that the approach adopted is generalisable to a broad category of mobile computing applications.1396Scopus© Citations 4 - PublicationMobile multimedia : reflecting on dynamic service provisionDelivering multimedia services to roaming subscribers raises significant challenges for content providers.

However, the archetypical mobile user differs from the conventional user in a number of aspects; of these the most important is context. Synonymous with mobile computing is the context concept, and factoring the availability of select contextual elements into the design of digital libraries offers significant opportunities for adapting and personalising services for the mobile computing community. This paper proposes the Ambient Digital Library as a construct for integrating digital content, contextual parameters and user models. In this way, a digital library may be made more accessible to a broader category of mobile user.
432Scopus© Citations 3 - PublicationDelivering Adaptivity through Context AwarenessDeveloping applications and deploying services for mobile users raises a number of issues and challenges that must be successfully addressed before the era of truly ubiquitous computing will dawn. In particular, the desire to deploy rich multimedia applications and services is severely curtailed by the limited capabilities of the current range of mobile devices as well as the limited bandwidth of current wireless cellular networks. How best to overcome these limitations remains the focus of much research. Intelligent agents have been demonstrated as a promising solution for inherently complex and dynamic domains and their use is proposed as the basis of a solution for assembling and disseminating multimedia content to a mobile audience. Attention is particularly directed to issues concerning the adaptation of content according to the end-user physical context and their personal profile or model.

Some of these difficulties arise from structural and economic issues; others may be sociological and demographic. However, to thrive, retailers must be perceived as being competitive, and must adopt innovative and invigorating strategies to maximise the potential of their situations while offsetting the limitations. In this paper, it is proposed that a judicious combination of low-cost Information and Communication Technologies (ICTs) could enable small retailers harness the benefits of the information society and provide services congruent with the digital city concept. As an illustration of the issues involved, pertinent results from a systematic end-user evaluation of Easishop are discussed.
