A review on energy harvesting and storage for rechargeable wireless sensor networks

摘要

Wireless sensor networks with battery-operated nodes have the limitation in the energy availability at each node. One visible solution is to add the nodes with energy harvesting capability. By harnessing energy from the environment or other sources, the nodes can prolong its operation. This paper provides a brief review of energy harvesting systems - protocol, energy sources, and storage technologies. The study also discusses some opportunities offurther research on energy harvesting networks.
