| Summary: | Energy harvesting wireless networks is one of the most researched topics in
this decade, both in industry and academia, as it can offer self-sustaining
sensor networks. With RF energy harvesting (RF-EH) embedded, the sensors
can operate for extended periods by harvesting energy from the environment
or by receiving it as an Energy signal from a hybrid base station (HBS). Thus,
providing sustainable solutions for managing massive numbers of sensor
nodes. However, the biggest hurdle of RF energy is the low energy density due
to spreading loss. This paper investigates the RF-EH node hardware and design
essentials, performance matrices of RF-EH. Power management in energy
harvesting nodes is discussed. Furthermore, an information criticality
algorithm is proposed for critical and hazardous use cases. Finally, some of the
RF-EH applications and the opportunities of 5G technologies for the RF-EH
are introduced. |
