With a cell phone camera a person can take pictures and imme diately transmit them to larger repositories using telecommunication channels. This provides the potential for anywhere, anytime picture sharing and story telling. It can also increase awareness among peers within a social network. But while we enjoy telli ng stories around this informal content, the necessary act of downloading, organizing and then presenting the digital media is tedious and can discourage frequent use. We present PLOG, an application that stresses ease-of-use story telling through cell pho ne photography. The user simply takes pictures and performs simple click -and-send uploads using their phone. From a local machine, PLOG automatically downloads the images; time clusters the pictures together and then presents them as story vignettes. These vignettes can be viewed different ways and at home, shared with friends or posted in public places. We describe the implementation of PLOG and di scuss issues related to this light -weight method of story telling and awareness.

Future mobile Ad hoc networks (MANETs) are expected to be based on all-IP architecture and be capable of carrying the multitude of real time multimedia applications such as voice, video and data. It is very necessary for MANETs to have an efficient routing and quality of service (QoS) mechanism to support diverse applications. In this paper, we propose a novel node-disjoint Multipath QoS Routing protocol for supporting DiffServ (MQRD). Simulation results show that MQRD achieves better performance in terms of packet delivery ratio and average delay.

Ubiquitous data mining (UDM) allows data mining operations to be performed on continuous data streams using resource limited devices. Visualisation is an essential tool to assist users in understanding and interpreting data mining results and to aide the user in directing further mining operations. However, there are currently no on-line real-time visualisation tools to complement the UDM algorithms. In this paper we investigate the use of visualisation techniques, within an on-line real-time visualisation framework, in order to enhance UDM result interpretation on handheld devices. We demonstrate a proof of concept implementation for visualising degree of membership of data elements to clusters produced using fuzzy logic algorithms.

In our paper we discuss a novel P2P file sharing system optimized for smart phones, using proximity networking. Group management, peer discovery and proximity multicasting are discussed. The experiment with the proof-of-concept implementation on the Series S60 Symbian platform shows that content sharing in social proximity can happen in a costand resourceeffective way.

This paper gives an insight on the services that are necessary for a system capable of supporting one practical application of the concept of Ubiquitous Computing. The applied scenario is an academic campus and it is pretended that students may access typical computer applications ubiquitously, i. e., anywhere and using any computer. We call it Universal Access to Applications. In this scenario, each user may access and use an arbitrary, and heterogeneous, set of applications on any computer and anywhere in the campus. A survey on technologic solutions for enabling the access to non-native applications is firstly summarized. Then we proceed with the design of such distributed system using MoNet methodology. Four steps are covered together with their main contributions: requirements capturing, design of a Logical Model, elaboration of a Functional Model, and finally, setting of a Reference Model for implementation. The proof-of-concept platform, developed on basis of the designed system, proved the concept. Finally, conclusions about the work done and the concept future applications are considered.

Our paper draws on research work conducted in association with the UK electricity supply industry to design and deliver a context aware application for field engineers. This research identified clear business benefits and the need for intelligent information flow algorithms, which could match information delivery requirements to the capability of the delivery networks. In turn, our work has now resulted in a proposed generic model for the design and operation of a mobile context aware distributed system. The core objective of this research is the derivation of an algorithm to allow the efficient delivery of information to a user, based on the user’s context. The pseudo-code for this algorithm is presented, together with an overview of the inputs to this algorithm, of which user context is one, and the issues surrounding them. Finally there is a look towards the future and possible further refinements that might be performed on the algorithm, namely the application of fuzzy logic. ...

The term “service” is quite overused in the telecommunications research area. This paper continues previous research by the author toward a better understanding of the service concept. The term service in this paper means the “something” that a human user receives from the computing environment that includes mobile and fixed devices, various kinds of interconnected networks forming a larger whole, and a variety of existing software. The main concern of this paper is to derive a set of essential properties of services within heterogeneous networks. It also defines the relationships among established properties and references each of them to a certain functional layer within a service conceptual model. Finally, this paper represents an example of “service content value”-based classification and the service characterization framework using an ontological representation

This work is related to the area of Component-based Software Development, particularly to largely distributed systems as Pervasive Computing Environments. We are focused on the automation of a Component Integration Process as a support for run-time adjustments of applications when the environment involves highly dynamic changes of requirements. Such integration implies to evaluate whether components may or may not satisfy a given model. The Assessment procedure is based on syntactic and semantic aspects, where the latter involves assertions, and usage protocols. We have implemented on the .Net technology the current state of our approach to gain understanding about the complexity and effectiveness of our approach.

The paper deals with the design of an intelligent user interface augmenting the user experience in a museum domain, by providing an immersive audio environment. We highlight the potential of augmenting the visual real environment in a personalized way, thanks to context modeling techniques. The LISTEN project, a system for an immersive audio augmented environment applied in the art exhibition domain, provides an example of modeling and personalization methods affecting the audio interface in terms of content and organization. In addition, the outcomes of the preliminary tests are here reported.
