No. of bitstreams: 1 Luthiano.pdf: 2917116 bytes, checksum: 1552e3d64f89b78bc1ba5b80c02ad3be (MD5) Previous issue date: 2010-03-29 / This work was aimed at the proposition of a mechanism for context awareness in ubiquitous computing. With technological advances we have smaller and smaller devices and greater computing power and communication which enhances the mobility of the User when carrying their equipment. In this sense, a ubiquitous environment requires the existence of different devices such as sensors, actuators and electronics in general that interact in different ways with users. The diversity of devices and information in a ubiquitous environment as it is, introduces different challenges for interoperability between the different parties involved. Therefore, when building and running applications ubiquitous context-aware, a number of features that should be provided, involving the acquisition of contextual information from the set of heterogeneous sources and distributed to the representation of the information and its processing . With a view to meet these demands of ubiquitous computing, is designed to EXEHDA-SS, to be responsible for processing the contextual information for tasks of manipulation and deduction from the context using ontologies for the representation and processing of contextual information using semantic support / Este trabalho tem como objetivo central a proposic¸ ao de um mecanismo para sensibilidade ao contexto na computac¸ ao ub´ıqua. Com os avanc¸os tecnol´ogicos temos dispositivos cada vez menores e com maior poder de computac¸ ao e comunicac¸ ao o que potencializa a mobilidade do usu´ario quando portando seus equipamentos. Neste sentido, um Ambiente Ub´ıquo pressup oe a exist encia de diferentes dispositivos, tais como sensores, atuadores e eletroeletr onicos em geral que interagem de diferentes maneiras com os usu´arios. A diversidade de dispositivos e informac¸ oes de um Ambiente Ub´ıquo assim constitu´ıdo, introduz diferentes desafios para interoperabilidade entre as diferentes partes envolvidas. Portanto, ao se construir e executar aplicac¸ oes ub´ıquas sens´ıveis ao contexto, h´a uma s´erie de funcionalidades que devem ser providas, envolvendo desde a aquisic¸ ao de informac¸ oes contextuais, a partir do conjunto de fontes heterog eneas e distribu´ıdas, at´e a representac¸ ao dessas informac¸ oes, e seu processamento. Na perspectiva de atender estas demandas da computac¸ ao ub´ıqua, foi concebido o EXEHDA-SS, para ser respons ´avel pelo tratamento das informac¸ oes contextuais, realizando tarefas de manipulac¸ ao e deduc¸ ao sobre o contexto, utilizando ontologias para a representac¸ ao e processamento das informac¸ oes contextuais empregando suporte sem antico .
