Resumo
According 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.
