D-LITe: Distributed Logic for Internet of Things Services

Smartphones, PDA, Sensors, Actuators, Phidgets and Smart Objects (i.e. objects with processing and networking capabilities) are more and more present in everyday´s life. Merging all these technologies with the Internet is often described as ´Internet of Things´ (IoT). In the IoT vision, Things around us provide a pervasive network of interacting and interconnected devices. However building IoT applications is a long and arduous work, reserved for specialists, requiring specific knowledge´s in terms of network protocols and programming languages. The lack of widespread and easy-to-configure solutions is an obstacle for the development of this area. A universal framework, offering simplification and standardization, could facilitate the emergence of this promising field in terms of applications and business. IoT needs a solid foundation for rapid, simple development and deployment of new services. In this paper, we present D-LITe, a universal framework for building IoT applications over heterogeneous sets of small devices. D-LITe offers solutions for deploying application´s logic, and executing it on Smart Objects despite their heterogeneity. An implementation of D-LITe on tiny devices, such as TelosB motes, allows to show that our framework is realistic even with the constraints of such devices.
