A Context-Oriented System For Mobile Devices

Our work provides developers of context-based application for mobile devices a framework for developing comprehensive and adaptable solutions that can interacts each other through a set of functionalities and interaction methods for building secure applications easily. On the other hand, our work provides a platform to reduce the energy consumption of the devices; due to the reuse of functionalities. To do this, we have designed a layered architecture that allows interaction between applications and context­ oriented services transparently to users. The main layer of our architecture (Core layer) provides a tool that allows communication between adjacent layers. More over, using our architecture, developers can design context-based applications in a simpler way, a very important goal in order to increasing number and functionalities of this kind of applications on mobile devices. Furthermore, our architecture allows the reuse ofknowledge between developers. During our work, OSGi technology has been used in mobile phones, cutting-edge research in the field.
