Energy harvesting

Abstract

"A wireless Sensor Network (WSN) is a network of spatially distributed autonomous sensors deployed in the environment in order to cooperatively monitor physical or environmental conditions such as temperature, sound, pressure, motion or pollutants at different locations. Each node in a sensor network is equipped with a radio transceiver, a microprocessor and an energy source such as a battery which should be replaced periodically. To increase the lifetime of the network keeping the small size in mind, methods should be put in place to reduce the power consumption of the sensor node or increase the node life and/or to supply power to the battery from external sources. In this thesis, the first paper presents an energy-efficient frequency adaptation based approach to minimize the power consumption of the microprocessor in an attempt to increase the lifetime of the sensor node...The second paper, on the other hand, presents an energy harvesting circuitry to charge the battery of the sensor node so that the time to replacement can be extended"--Abstract, page iv.
