DAAF: A Device Abstraction and Aggregation Framework for Smart Environments

Largely motivated by the ubiquitous computing vision, computers have been steadily becoming integrated in people's life, expanding the ability of software applications to interact with the environment and the users. This has led to the creation of smart environments that support people in their daily life by exploiting information acquired using sensor networks. These systems are usually populated by multiple non-interoperable technologies that make the development, deployment and reutilization of applications a complex and repetitive task. This paper presents DAAF, a Device Abstraction and Aggregation Framework that provides a common conceptual model of a device network, and a set of tools, which allow a flexible integration of heterogeneous sensor networks, enabling fast development and reconfiguration of smart environment applications.
