dc.description.abstractAccording to Mark Weiser, ubiquitous computing focuses on seamlessly integrating computing tasks into people’s daily lives. Because of current technology limitations, the realization of ubiquitous computing observes a limited set of aspects of ubiquitous computing, such as, mobility and context, which are based on services that integrate the users with the resources that are present on a delimited ubiquitous environment (such as in smart spaces). Instead, we explored a different approach, in which services are used not to integrate an individual user with the environment, but to integrate the users present in the environment with one another. One way to realize this aspect is by using content sharing, first-class application dat, that serve as integration medium between users. However, due to the environment complexity and lack of middleware platforms, applications that follow this approach are repeatedly built from scratch using raw techniques. Aiming to provide an infrastructure for the development of this kind of applications, we propose Content Sharing for Smart Spaces (C3S), a middleware that offers a high-level programming model using primitives that are based on a set of content sharing semantics and ubiquitous application concepts. The primitives express a small set of behaviors, such as move, clone, and mirror, which serve as building blocks for developers to implement sharing and content ubiquity features, while the ubiquitous concepts supported by the middleware allow the manipulation of users, groups and ubiquitous applications. We validated our proposal using two different case studies that allowed us to explore these features. Our results show that our middleware provides an easier way to develop sharing-based applications compared to related work found in the literature.eng

dc.description.resumoDe acordo com Mark Weiser, a computação ubíqua se concentra na integração de maneira despercebida e sem rupturas (seamlessy) de tarefas da computação no cotidiano das pessoas. Por causa das atuais limitações tecnológicas, a realização dessa integração segue um ou mais aspectos da computação ubíqua, por exemplo, de mobilidade ou de contexto, que são baseados em serviços que integram o usuário em um ambiente ubíquo delimitado (como espaços inteligentes). Neste trabalho exploramos uma abordagem diferente, em que os serviços não são utilizados para integrar um usuário individual ao ambiente, mas são utilizados para integrar os usuários presentes no ambiente uns com os outros. Uma maneira de realizar esse aspecto é usando o compartilhamento de conteúdo, dados de primeira classe da aplicação que servem como meio de integrar os usuários. No entanto, devido à complexidade do ambiente de computação ubíqua e à falta de plataformas de middleware, aplicações que seguem esta abordagem são repetidamente construídas a partir “do zero”, usando técnicas não convencionais. Com o objetivo de fornecer uma infraestrutura para o desenvolvimento deste tipo de aplicação, propomos o Content Sharing for Smart Spaces (C3S), um middleware que oferece um modelo de programação de alto nível, usando primitivas baseadas em um conjunto de semânticas de compartilhamento de conteúdo e em conceitos de aplicações ubíquas. As primitivas expressam um conjunto de comportamentos, tais como mover, clonar, e espelhar, que servem como blocos de construção para os desenvolvedores implementarem funcionalidades de compartilhamento, enquanto que os conceitos de ubiquidade permitem a manipulação de usuários, grupos e aplicações ubíquas. A proposta foi validada por meio de dois estudos de caso que exploram esses recursos. Os resultados permitiram concluir que o middleware fornece uma maneira mais fácil de desenvolver aplicativos baseados em compartilhamento em comparação com trabalhos semelhantes encontrados na literatura.por
