Infraestrutura para o desenvolvimento de aplicações pervasivas com suporte ao chaveamento automático de tecnologia de comunicação.

Abstract

As predicted by Weiser about twenty years ago, the ubiquitous computing era in which technology integrates people's lives in such way that they do not even realize it has become reality. This new paradigm has become possible thanks to the popularization of devices such as smartphones and tablets that combined with the extraordinary progress of wireless technologies for short and long range, have made possible scenarios for pervasive applications. However, pervasive applications require the developer to deal with issues such as: (i) extract from the environment they are inserted context information as user's presence, (ii) handle the need for successive changing communication technologies for short and long range due to high dynamicity of the environments. This work presents an infrastructure for supporting pervasive applications developers, providing an abstraction for the complexity related to the communication and to the context-aware switching between communication technologies present in these devices. The validation is performed through a case study that utilizes NFC, Bluetooth and Wi-Fi technologies, with management of these technologies according to application needs.
