ULTRA LOW POWER SUB-WIRELESS SENSOR NETWORK (SUB-WSN) FOR INTERNET OF THINGS (IOT) SYSTEM

摘要

The present invention provides a sub-WSN for an IoT system having at least a sensor node, and a sub-sensor node and a sub-gateway for the sub-WSN, so as to solve the problems of low channel quantity and high power consumption in the prior art. The sub-WSN comprises: a sub-gateway and a plurality of sub-sensor nodes. The sub-gateway is wiredly coupled to the Sensor node. The sub-sensor nodes are utilized for sensing and wirelessly communicating with the sub-gateway via RF signals.
