Recently, as more and more mobile devices embedded with intelligent software become part of our daily lives, Open Services Gateway initiative (OSGi) has gained increasing attention in the development of services for such devices. However, services residing in OSGi platforms are devised specifically for the platforms' local bundles. Although several works have enhanced OSGi with various communication...
The contribution outlines basic principles of mobile architecture M client M client server. This architecture comprises ideas of the new proposal/design of communication between/among mobile devices in common wireless networks and is not restricted to GSM networks only. Basic architecture elements of this model are described in the article. Similarities with other systems (for example multi agent...
This paper presents the use of Near Field Communication and mobile technologies for the development of ubiquitous games. We describe all the components necessary for the building of ubiquitous games: the MIDlet or program running on the mobile phone with NFC features, the services available in the back-end system in charge of the game control and the tool devoted to real-time surveillance and visualization...
In this paper, we present further research achievements due to hand-OLAP, a Java-based distributed system that relies on semantics-based intelligent data cube compression techniques, and effectively and efficiently supports OLAP in mobile environments. Hand-OLAP is based on a systematic approach according to which first a two-dimensional OLAP view of interest is extracted from the target multidimensional...
Health care systems will integrate new computing paradigms in the coming years. Context awareness computing is a research field which often refers to health care as an interesting and rich area of application. One of the areas for context aware computing is social awareness amongst a group of individuals. Providing individuals with social awareness about other coworkers is very important in order...
