This study reports a measurement-based assessment of outdoor downlink RF-EMF exposure in a French city using drive testing, spot measurements, and a streetlamp-mounted sensor network. The authors report good agreement across methods and correlations between smoothed drive-test data, spot measurements, and base…

This in vitro study evaluated SAR and erythrocyte membrane stability during exposure to a fully textile wearable antenna at 2.41 GHz under realistic (6.3 mW) and conservative (450 mW) input power conditions. It reports 1 g average SARs of 0.5758 W/kg and 41.13 W/kg, respectively. For membrane stability at 6.3 mW,…

This engineering paper presents an experimentally validated wearable personal exposimeter system for RF-EMF exposure monitoring, motivated by increasing wireless applications. It uses a distributed measurement approach and integrates inertial sensors to capture activity and posture during measurements. The system is…

This engineering study develops and experimentally evaluates a fuzzy-logic method for locating mobile robots in an intelligent space using wireless sensor networks. Localization relies on inter-node range measurements estimated from RF signal strength attenuation, which the authors describe as noisy and unreliable.…

This engineering paper describes low-power wireless sensor nodes and a cluster-based dynamic-tree hierarchical WSN architecture for monitoring historical buildings and wooden artifacts for early pest detection. The authors report simulation and demonstration results indicating improved scalability and reliability…

This article reports an engineering implementation of a wireless sensor network-based remote water-level monitoring system. The system includes field sensors, a base station, a data center, and a web publishing module, and is described as providing real-time monitoring and anti-jamming capability. The authors state…

This engineering paper introduces an RFID sensor network concept integrating RFID with wireless sensor networks and emphasizes the role of antennas. It discusses coil, dipole, and microstrip antennas and reports designing a microstrip antenna for a wireless temperature monitoring and control system. Measurements are…
