On the design of pervasive computing applications based on Bluetooth and a P2P concept
2006
As an example of implementing the pervasive computing, we developed an application framework to deploy an easy, spontaneous, and infrastructureless network. We selected the Bluetooth technology with the peer-to-peer (P2P) concept to develop an experimental application which enables peers to exchange their resources. Overall network architecture and the prototype application are presented. We selected a small test-bed and simulation to evaluate the overall performance and system behaviour. We measured and present our findings in term of the duration of inquiry procedure and the throughput, according to various experimental parameters such as physical distance between nodes and their speeds.
A User-Centric Approach for Personalized Service Provisioning in Pervasive Environments
2011
Published version of an article published in Wireless Personal Communications (2011). Also available from the publisher at http://dx.doi.org/10.1007/s11277-011-0387-3 The vision of pervasive environments is being realized more than ever with the proliferation of services and computing resources located in our surrounding environments. Identifying those services that deserve the attention of the user is becoming an increasingly-challenging task. In this paper, we present an adaptive multi-criteria decision making mechanism for recommending relevant services to the mobile user. In this context, "Relevance" is determined based on a user-centric approach that combines both the reputation of the…
Mobile Computing Environment
2002
A conceptual framework for ubiquitous mobile environments.
2008
The aim of this paper is to reflect upon and develop a conceptual framework that addresses the relationship between real and virtual life, with a particular focus on mobile gaming as one potential methodology for learning. The comprehension of the virtual-real life relationship is relevant not only to mobile gaming, but also to the ongoing discussions about and development of ubiquitous computing.
The Brave New World of development in the internetwork computing architecture (InterNCA): or how distributed computing platforms will change systems …
1998
This essay is a speculation of the impact of the next generation technological platform — the internetwork computing architecture (InterNCA) — on systems development. The impact will be deep and pervasive and more substantial than when computing migrated from closed computer rooms to ubiquitous personal computers and flexible client-server solutions. Initially, by drawing upon the notion of a technological frame, the InterNCA, and how it differs from earlier technological frames, is examined. Thereafter, a number of hypotheses are postulated with regard to how the architecture will affect systems development content, scope, organization and processes. Finally, some suggestions for where the…
A Dynamic System for Personal Communications: The Opportunistic Chat
2007
most of currently available inter-personal instant messaging systems are client-server based. Users of such systems need to be connected to some centralized entity which goal is to supply them with information needed to make the communication possible, such as the list of connected users, their status, and the address of their devices. Our proposed system for an “Opportunistic Chat” allows people to exchange written messages over Bluetooth and (if necessary) TCP/IP connections, with no need of any kind of centralized entity, by using ad-hoc procedures, automatically selected and operated. Such system can be accessed almost from any kind of device, either mobile or not, ranging from personal…
Mobile Interface for Content-Based Image Management
2010
People make more and more use of digital image acquisition devices to capture screenshots of their everyday life. The growing number of personal pictures raise the problem of their classification. Some of the authors proposed an automatic technique for personal photo album management dealing with multiple aspects (i. e., people, time and background) in a homogenous way. In this paper we discuss a solution that allows mobile users to remotely access such technique by means of their mobile phones, almost from everywhere, in a pervasive fashion. This allows users to classify pictures they store on their devices. The whole solution is presented, with particular regard to the user interface impl…
Platforms for Human-Human Interaction in Large Social Events
2012
In this paper we present the evolution of QRouteMe, an information system built to provide people with rich user experiences when attending museums or exhibits. QRouteMe is a platform for indirect, mediated, and facilitated interactions among humans during large social events, by means of a wide variety of concurrent technologies and devices. The system evolution is analyzed according to the new human-to-human interaction (HHI) research domain. In particular, we show how QRouteMe has been adapted for the different events in which it has been used. We analyze and describe social interaction aspects during the events and we discuss some data and results. Finally we outline some possible futur…
An Agent-based Service Network for Personal Mobile Devices
2006
We propose the Agent Network for Bluetooth Devices, a system that uses personal mobile devices as adaptive human-environment interfaces to supply people with ad hoc information and high-level services. The ANBD system operates with a hierarchical framework of service-providing nodes, dynamically composed and managed by mobile agents.
A Mobile Computing Framework for Pervasive Adaptive Platforms
2012
International audience; Ubiquitous computing is now the new computing trend, such systems that interact with their environment require self-adaptability. Bioinspiration is a natural candidate to provide the capability to handle complex and changing scenarios. This paper presents a programming framework dedicated to pervasive platforms programming. This bioinspired and agentoriented framework has been developed within the frame of the PERPLEXUS European project that is intended to provide support for bioinspiration-driven system adaptability. This framework enables the platform to adapt itself to application requirements at high-level while using hardware acceleration at node level. The resu…
