Uma abordagem baseada em componentes para o desenvolvimento de aplicações pervasivas cientes de contexto de ambiente: foco em sensores.

Abstract

The pervasive computing is a paradigm which the computer becomes ubiquitous and invisible to the user with the ability to get information about the surrounding environment and use them to control, configure and tune applications dynamically. Pervasive systems are characterized by the use of sensors, which capture data from the environment, and then processes, to provide personalized services to users. In certain environments, the main sensor data generator is the personal portable device, which has several built-in sensors, such as smartphones and tablets. From a software development perspective there is a great effort in acquisition, treatment and data processing, especially considering different platforms, device model and device manufacturers. In this work, we propose a component-based approach to develop pervasive applications based on the environmental context by providing services which uses sensor data. The validation of our approach was an experiment which developers used the Android platform. Results show a reduction in the development time and the number of lines generated using this approach.
