Abstract :
This paper proposes a network traffic simulation model for BACnet Web service (BACnet/WS) object access of building facility monitoring systems to evaluate the communication performance. The simulation model was verified by experiments using a network traffic emulator. In our simulation study, access times of BACnet/WS for 1000 objects are approximately 5 to 20 times longer than those of BACnet/IP. In addition, the study indicates that there exists an optimum number of objects, i.e. the length of each BACnet/WS message in the cases of heavy background traffic.
