Olympus: The Cloud of Sensors

The cloud of sensors (CoS) paradigm emerged from the broader concept of the cloud of things. CoS infrastructures are built on the concept of wireless sensor and actuator network (WSAN) virtualization and have the potential to leverage the benefits of both cloud computing and WSANs. However, WSAN virtualization is still in its infancy within the CoS paradigm. Existing approaches are centralized CoS infrastructures that consider smart sensors only as passive data providers, which don´t take full advantage of these devices. The authors propose a decentralized WSAN virtualization model based on information fusion. The model, termed Olympus, seeks to leverage the CoS paradigm to make the best use of both the cloud and physical WSAN environments.
