Implementation of Wireless Sensor Networks for Industrial Automation Applications

Abstract

Industrial automation systems increasingly require flexible sensing, rapid deployment, continuous condition monitoring, and dependable communication in environments where extensive cabling is expensive or impractical. This methodology paper presents a structured implementation framework for an Industrial Wireless Sensor Network (IWSN) intended for monitoring and supervisory automation applications. The proposed architecture combines low-power sensor nodes, multi-hop wireless communication, an industrial gateway, and a PLC/SCADA interface. The methodology emphasizes node selection, radio planning, topology design, time-aware communication, reliability mechanisms, security, commissioning, and performance evaluation. Earlier studies established that WSNs can provide self-organization and low-cost sensing, while industrial use additionally requires predictable latency, high packet delivery, resilience to interference, and secure integration with control infrastructure (Akyildiz et al., 2002; Gungor & Hancke, 2009). The implementation therefore uses an IEEE 802.15.4-class physical layer with mesh redundancy and a WirelessHART-inspired schedule for critical traffic. A controlled evaluation scenario is defined using temperature, vibration, pressure, and current sensing nodes. Representative methodology-validation results show that redundant routing and scheduled transmissions can improve packet delivery and reduce latency variation compared with an unscheduled single-path configuration. The study concludes that IWSNs are appropriate for industrial monitoring and selected supervisory control functions when deployment is preceded by radio-site assessment and when reliability, security, and gateway integration are treated as primary engineering requirements rather than optional additions.
