BACnet over ZigBee, A new approach to wireless datalink channel for BACnet

BACnet(Building Automation and Control Networks) is a standard data communication protocol specifically designed for building automation and control systems, BACnet provides six options for data link layer protocols and these six data link layer options can be applied with various wired transmission media. Recently wireless technology prevails in automation area. ZigBee is an IEEE 802.15.4 based standard communication protocol for low-rate wireless personal area networks. In this study, we propose a BACnet over ZigBee model that adopts ZigBee communication channel as a wireless data link layer protocol in a BACnet-based communication network system. We also applied this model to an experimental model to evaluate the feasibility of proposed technology. The technology proposed in this paper can expand the BACnet application using the advantages of wired and wireless integrated network solution.
