What is RFID in Wireless Sensor Networks?
RFID in Wireless Sensor Networks integrates passive RFID tags with WSN nodes to enable low-power identification, sensing, and data communication in IoT applications.
Hybrid RFID-WSN systems combine RFID's identification capabilities with WSN's sensing for applications like environmental monitoring and supply chain tracking. Key advancements include ambient backscatter for battery-free operation (Liu et al., 2013, 1091 citations) and inkjet-printed antennas on paper substrates (Rida et al., 2009, 350 citations). Over 10 papers from the list address energy harvesting, data fusion, and scalability, with Landaluce et al. (2020, 383 citations) reviewing sensing challenges.
Why It Matters
RFID-WSN convergence enables battery-free IoT sensing in smart agriculture and cities, as shown in ambient backscatter systems harvesting TV signals for communication (Liu et al., 2013). Structural health monitoring uses RFID tag antennas for crack detection without power sources (Zhang et al., 2017). Supply chain integration with RFID improves tracking efficiency (Asif and Mandviwalla, 2005), while wearable textile antennas support body sensor networks (Salvado et al., 2012). These systems reduce deployment costs in pervasive monitoring.
Key Research Challenges
Energy Harvesting Limitations
RFID-WSN nodes rely on RF harvesting, limiting range and data rates in low-signal environments. Liu et al. (2013) demonstrate ambient backscatter using TV signals but note power constraints for dense networks. Scalable harvesting remains unsolved for mobile deployments.
Data Fusion Complexity
Integrating RFID identification with WSN sensor data requires efficient protocols amid interference. Landaluce et al. (2020) highlight fusion challenges in IoT sensing applications. Real-time aggregation demands low-latency algorithms.
Network Scalability Issues
Dense RFID-WSN deployments face collision and bandwidth limits. Rida et al. (2009) discuss inkjet-printed antennas for UHF RFID-WSN but identify scaling hurdles in mass production. Anti-collision protocols need optimization for thousands of tags.
