[en] FIOT: AN AGENT-BASED FRAMEWORK FOR SELF-ADAPTIVE AND SELF-ORGANIZING INTERNET OF THINGS APPLICATIONS / [pt] FIOT: UM FRAMEWORK BASEADO EM AGENTES PARA APLICAÇÕES AUTO-ORGANIZÁVEIS E AUTOADAPTATIVAS DE INTERNET DAS COISAS

NATHALIA MORAES DO NASCIMENTO 01 June 2016 (has links)
[pt] A ideia principal da Internet das Coisas (IoT) é conectar bilhões de coisas à Internet nos próximos anos, a exemplo de carros, roupas e comidas. Entretanto, muitos problemas precisam ser resolvidos antes que essa ideia possa ser concretizada. Alguns desses problemas estão relacionados à necessidade de construir sistemas para IoT que sejam auto-organizáveis e autoadaptativos. Este trabalho, portanto, apresenta a elaboração do Framework para Internet das Coisas (FIoT), que oferece suporte ao desenvolvimento de aplicações para IoT com essas características. Ele é baseado nos paradigmas de Sistemas Multiagente (SMA) e algumas técnicas abordadas em Aprendizado de Máquina, a exemplo de redes neurais e algoritmos evolutivos. Um agente pode ter algumas características, como autonomia e sociabilidade, que tornam SMAs compatíveis com sistemas que requerem auto-organização. Redes neurais e algoritmos de evolução vêm sendo comumente usados nos estudos de robótica, no intuito de prover autonomia e adaptação à agentes físicos (ex.: robôs, sensores). Para demonstrar o uso do FIoT, dois grupos de problemas em IoT serão instanciados: (i) Cidades Inteligentes e (ii) Quantificação de Coisas. / [en] The agreed fact about the Internet of Things (IoT) is that, within the coming years, billions of resources, such as cars, clothes and foods will be connected to the Internet. However, several challenging issues need to be addressed before the IoT vision becomes a reality. Some open problems are related to the need of building self-organizing and self-adaptive IoT systems. To create IoT applications with these features, this work presents a Framework for Internet of Things (FIoT). Our approach is based on concepts from Multi-Agent Systems (MAS) and Machine Learning Techniques, such as a neural network and evolutionary algorithms. An agent could have characteristics, such as autonomy and social ability, which makes MAS suitable for systems requiring self-organization (SO). Neural networks and algorithms of evolution have been commonly used in robotic studies to provide embodied agents (as robots and sensors) with autonomy and adaptive capabilities. To illustrate the use of FIoT, we derived two different instances from IoT applications: (i) Quantified Things and (ii) Smart Cities. We show how exible points of our framework are instantiated to generate an application.
