Resumo
Os avanços dos últimos anos nas áreas da micro-electrónica e telecomunicações ajudaram a materializar a visão de um modelo computacional ubíquo, onde através da incorporação de sensores e interfaces de comunicação em objectos do nosso quotidiano é possível em tempo real a troca de informação colaborativa e dinâmica entre os mesmos. A acompanhar este fenómeno temos assistido ao aparecimento de sistemas que servem de interface a esta rede globalizada de sensores, permitindo não só a disponibilização imediata dos dados sensoriais recolhidos, bem como a interconectividade entre os diferentes dispositivos na rede. Esta tese faz uma análise comparativa destas plataformas e sistemas, desde a forma como se organizam, suas características, arquitectura de sistemas, utilidade, forças e fraquezas e neste contexto especifica e implementa o projecto Maestroo, um sistema embebido concebido para ambientes sensoriais imersivos baseado na virtualização e partilha de sensores. O Maestroo permite que dispositivos móveis ou fixos com diferentes sistemas operativos armazenem, disponibilizem e partilhem de uma mesma forma dados sensoriais, bem como o acoplamento de forma virtualizada de sensores que existem fisicamente noutros dispositivos. O projecto cria uma rede privada de três nós e permite a partilha de informação sensorial entre os mesmos. Esta rede foi criada para demonstrar as funcionalidades e capacidades deste software, não estando de qualquer forma restringida a esse número de nós. Toda a arquitectura, concepção e implementação do Maestroo são descritos pormenorizadamente, bem como as suas aplicações práticas e trabalho futuro.
The advances of recent years in the areas of microelectronics and telecommunications helped to materialize the vision of a ubiquitous computing model, where through the incorporation of sensors and communication interfaces in objects of everyday life it is possible in real-time, the exchange of collaborative and dynamic information between them. Accompanying this phenomenon we have seen the emergence of systems that act as interfaces for this global sensor network, allowing not only the immediate availability of sensory data collected as well as interconnectivity between the different devices on the network. This MSc Thesis makes a comparative analysis of these platforms and systems, from the way they are organized, features, system architecture, utility, strengths and weaknesses and in this context specifies and implements the project Maestroo, an embedded system designed for immersive sensing environments, based on virtualization and sharing of sensors. The Maestroo software allows mobile or fixed devices with different operating systems to store, make available and share in the same manner sensor data as well as the coupling of virtualized sensors that physically exist in other devices. The project creates a private network of three nodes and allows the sharing of sensory information between them. This network was created to demonstrate all software features and potentialities and it is not limited in any sense to that number of nodes. All the architecture, design and implementation of Maestroo are described in detail, as well as their practical applications and future work.
