METHOD AND SENSOR NODE FOR PROVIDING ADAPTIVE SAMPLING IN WIRELESS SENSOR NETWORKS

摘要

The present invention provides a method and a sensor node for providing an adaptive sampling in a wireless sensor network. According to an embodiment of the present invention, the sensor node providing an adaptive sampling in a wireless sensor network comprises: a sensing part sensing data; a control part processing the sensed data; a communication part transmitting the processed data to the outside according to control of the control part; and an energy storing part storing energy according to the control of the control part, or supplying the energy to at least one among the sensing part, the control part and the communication part. If harvesting quality is more than or equal to a predetermined level, the control part increases a current sampling cycle to control so that the sensing part senses the data, and controls so that the energy storing part stores the energy to be harvested. The energy of the sensor nodes composing the wireless sensor network can be saved, thereby ensuring self-sustainability.
