WIRELESS COMMUNICATION METHOD FOR MAGNETIC FIELD COMMUNICATION NETWORK AND DEMODULATION DEVICE OF COORDINATOR

摘要

The prevent invention relates to a wireless communication method for a magnetic field communication network and a demodulation device of a coordinator, capable of recognizing a plurality of sensor nodes for a short time. The wireless communication method for the magnetic field network of the present invention comprises: step (a) of transmitting a request signal to request a response to sensor nodes, which is performed by the coordinator in the magnetic field communication network; step (b) of selecting any one of response signals received from the sensor nodes; step (c) of transmitting an acknowledgement signal to the sensor node corresponding to the response signal selected in step (c); step (d) of selecting any one of the response signals retransmitted from the sensor nodes which do not receive the acknowledgement signal of step (c); and step (e) of transmitting the acknowledgement signal to the sensor node corresponding to the response signal selected in step (d).
