Performance analysis of Wireless Networks for Industrial Automation-Process Automation (WIA-PA)
MetadataShow full item record
The Wireless Networks for Industrial Automation-Process Automation (WIA-PA) standard is not well known in North America and is a relatively new industrial control system standard when compared to WirelessHart and ISA100.11A. An evaluation of the WIA-PA standard needs to be conducted by Department of Defense and its affiliates to determine whether its operation is on par with WirelessHart and ISA100.11A. The objective of this thesis is to provide a performance analysis of the WIA-PA standard. Utilizing MATLAB, we implemented a custom-built WIA-PA system model and measured the end-to-end delay, and received packet error rate and timeslot utilization. We expect WIA-PA to perform as well as WirelessHart and ISA100.11A in multiple network scenarios. We also found that due to the limitations of MATLAB, further analysis of the standard should be conducted on a network simulator such that network traffic can be properly emulated and the standard’s vulnerabilities can be further assessed.
