Integrating Building Automation Systems and Wireless Sensor Networks

Abstract

Building automation systems (BAS) are used to control and improve indoor building climate at reduced costs. By integrating BAS with wireless sensor networks, the need for cabling can be removed, and both installation and operational costs significantly reduced. Furthermore, temporary BAS installations are made possible. By implementing and evaluating the open BAS standard BACnet on the ESB nodes we show that using existing standard BAS protocols is possible on resource-constrained sensor nodes.
