Energy harvesting and consuming performance test system of chargeable wireless sensor network

Abstract

The invention discloses an energy harvesting and consuming performance test system of a chargeable wireless sensor network. The test system is composed of a radio-frequency energy source, a plurality of chargeable wireless sensing nodes and a data collecting and analyzing module; the radio-frequency energy source transmits an electromagnetic wave carrying information and energy; the chargeable wireless sensing nodes collect the electromagnetic wave transmitted by the radio-frequency energy source, convert the collected energy into a direct current to be supplied to the nodes and peripheral sensing equipment, use the collected information to realize the communication among the nodes and read the sensor information carried by the nodes themselves; the data collecting and analyzing module reads the sensing information of the chargeable wireless sensing nodes, processes the read information and analyses the energy harvesting and consuming performance of each node so as to assess the performance of the whole network. The energy harvesting and consuming performance test system of the invention provides a practical test platform for theoretical research of the chargeable wireless sensor network, evaluates validity of multiple chargeable wireless network energy optimization algorithms to network performance optimization, and provides correction parameters for improving the algorithms.
