A cloud-based architecture is presented for the internetworking of sensors and actuators through a universal gateway, network server and application user interface design. The proposed approach targets to Energy Efficiency and sustainability in a holistic way, by integrating an open-source test bed prototype based on long-range low-bandwidth wireless networking technology for sensing and actuation as the elementary block of a viable, cost-effective and reliable solution. The prototype presented is capable of supporting both sensors and actuators, processing data locally and transmitting the results of the imposed computations to a higher level node. Additionally, it is combined with a service-oriented architecture and involves publish/subscribe middleware protocols and cloud technology to confront with the system needs in terms of data volume and processing power. In this context, the integration of instant message (chat) services is demonstrated so that they can be part of an emerging global-scope eco-system of Cyber-Physical Systems to support a wide variety of IoT applications, with strong advantages such as usability, scalability and security, while adopting a unified gateway design and a simple – yet powerful - user interface.
