A Control and Decision System for Smart Buildings

The employment of a control and decision process supported by wireless sensor and actuator networks (WSANs) is a promising way to improve energy efficiency of Smart Buildings. We present and evaluate CONDE, a decentralized system for decision and control for Smart Building applications based on WSANs. Performed experiments shown that since data is processed within the network instead of transmitted to a central location, there is a gain in terms of the system response time and resource consumption. Therefore, CONDE improves the energy efficiency of both the monitored building and the WSAN infrastructure, when compared to centralized approaches. Moreover, it exploits integration of applications at the decision level to further improve the system efficiency.
