An open framework for accessing Things as a service

Integration of existing isolated vertical systems into a new horizontal environment is today one of the main challenges in making real the Internet of Things vision. The design of a platform to allow services and applications accessing physical objects from different environments is the main challenge of the BETaaS (Building the Environment for the Things as a Service) project. In this paper the solution adopted in BETaaS to expose heterogeneous things to applications through a service-oriented interface is presented. The goal is to design a single open framework in which existing solutions and architectures can be integrated with limited efforts and modifications. In order to demonstrate the feasibility of the proposed design, a simple proof-of-concept implementation is presented.
