This paper analyzes salient features of Industrial Automation-Process Automation (WIA-PA): mesh-star architecture, two-level aggregation, and adaptive frequency hopping, whose working principles are explicitly illustrated in comparison to the other two mainstream industrial wireless networks standards: WirelessHART and ISA 100.11a. In addition, performance analysis with respect to the three features of WIA-PA has been conducted in terms of communication overhead or transmission reliability. Our results demonstrate the performance advantages of WIA-PA over WirelessHART and ISA 100.11a.
