Fixed-mobile convergence (FMC) is the term used to describe a wide range of mobile services that converge elements of fixed communications infrastructure to complement the core mobile service. IP multimedia subsystem (IMS) is the approach towards merging the fixed and mobile worlds together with the Internet. It enables the efficient provision of an open set of highly integrated multimedia services,...
Health care management is a combined effort involving the patients and their families/caregivers, professional health care providers, medical schemes, support groups, and employers. Important to all stakeholders is the obtaining and sharing of credible information. The WWW currently allows the sharing and distribution of information that would otherwise not have been available, but it is plagued by...
In this paper we survey current research on Web issues in Argentina. We first describe briefly the current situation in computer science research and next we outline which are the most outstanding achievements in this area. Using the research areas in W3C conferences we describe the current projects, research groups and trends.
In order to provide a useful and usable mobile service that offers high value to customers to overcome the usability and performance constraints, this study suggests an user-centered design framework for development of new mobile Internet service. The proposed framework covers user characteristics, context of use, and user interface components of device and network. In a case study, integrated conceptual...
The remote labs or WebLabs promote the experimentation in the studies of engineering allowing the access and control of real laboratory equipment through Internet. In general a WebLab is a client-server application where the client application can only be used from a PC, and it is not considered the use of mobile devices as potential clients. This is due to the fact that the WebLabs are designed from...
This paper proposed a two layer authorization mechanism, including traditional password system and rhythm recognition. The whole system includes two phases: preprocessing and usual operation for users. In preprocessing phase, users type password in a specific rhythm in order to record and analyse the characteristics of behaviour of users. In the second phase, how to verify a user in usual operation...
The semantic Web attempts to make the Web an universal medium of data exchange. To achieve this it needs to both make data sources accessible to machine-based systems, such as software agents and allow humans to easily create, understand and search for these data sources. Crisp ontologies are extremely useful for improving data extraction from structured data. However many ontological approaches require...
The increased availability of mobile broadband connec- tions enables the expansion of software downloads to mobile devices. This leads to greater number of available services and a better utilisation of the computational power of mobile devices. The downside of this increased software availability is an increase in the possible attack vectors. One scenario is the misuse of resources, for example,...
The increasing ubiquity of mobile embedded systems has been matched by the evolution of a variety of wireless network standards and technologies. The major constraints of wireless embedded systems are limitations of communication bandwidth, processing capabilities, and battery power. Remote wireless embedded systems often act as sensors, which provide data to a certain community. The exchange of data...
Information privacy is usually concerned with the confidentiality of personally identifiable information (PII), such as electronic medical records. Nowadays, Web services are used to support different applications which may contain PII, such as healthcare applications. Thus, the information access control mechanism for Web services must be embedded into privacy-enhancing technologies. Further as application...
We developed a quality of service (QoS) management system to support service level management (SLM) for global enterprise services. The QoS management system is integrated with one of our enterprise services in a preproduction system, an identical system as the production system but in a test environment. Lab experiments showed that our integrated solution helps global enterprise services to better...
This paper explores the attributes, layering models and objective functions in cross layer designs for mobile ad hoc wireless networks by taking all the statistical characteristics and constraints from the physical (PHY) layer, media access control (MAC) layer and network (NET) layer into consideration. This paper reviews the entire network optimization across all the PHY/MAC/NET layers. At the PHY...
