MediaSense - an Internet of Things Platform for Scalable and Decentralized Context Sharing and Control

Research in Internet-of-Things infrastructures has so far mainly been focused on connecting sensors and actuators to the Internet, while associating these devices to applications via web services. This has contributed to making the technology accessible in areas such as smart-grid, transport, health, etc. These early successes have hidden the lack of support for sensor-based applications to share information and limitations in support for applications to access sensors and actuators globally. We address these limitations in a novel open-source platform, MediaSense. MediaSense offers scalable, seamless, real-time access to global sensors and actuators via hetero- geneous network infrastructure. This paper presents a set of requirements for Internet-of-Things applications support, an overview of our architecture, and application prototypes created in order to verify the approach in a test bed with users connected from heterogeneous networks.
