Reliability of Wireless Sensor Networks [PDF]
Sensors, 2014 Wireless Sensor Networks (WSNs) consist of hundreds or thousands of sensor nodes with limited processing, storage, and battery capabilities. There are several strategies to reduce the power consumption of WSN nodes (by increasing the network lifetime) and increase the reliability of the network (by improving the WSN Quality of Service).

Measurement Techniques and Challenges of Wireless LC Resonant Sensors: A Review
IEEE Access, 2023 Wireless operation of $LC$ resonant sensors is based on magnetic coupling between two inductive coils, where the inductor of the sensor acts as a secondary coil for the magnetic coupling. An external reader coil is used as a primary coil to interrogate
