C3S: A content sharing middleware for smart spaces

Abstract

Current sharing-based applications combine new computing devices with smart spaces to provide content-level ubiquity, i.e., the possibility to exchange and move content freely in a ubiquitous environment. However, due to the environment complexity and lack of infrastructure platforms, most of the work in the area is repeatedly built from scratch using raw techniques, such as socket and rpc, to express content sharing. 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. They express a set of behaviors, move, clone, and mirror, which serve as a building blocks for developers to implement sharing and content ubiquity features.

An architecture for a smart spaces virtual machine

“…Recent years witnessed great advances in wireless technologies and the popularization of increasingly compact and intuitive mobile devices such as tablets, smartphones and ultrabooks [14]. These devices, when used as part of a ubiquitous computing environment, allow us to build scenarios that were previously only glimpsed by the pioneers of ubiquitous computing such as the late Mark Weiser [16,22,14].…”

“…One particular type of ubiquitous computing environment is called smart space [5,13,14]. Smart spaces are bounded physical areas, e.g., rooms, floors and buildings, permeated with computational services that orchestrate the infrastructure of the environment, oriented to one or more aspects of ubiquitous computing [13,14], such as mobility and pervasiveness.…”
