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

摘要

Disclosed herein is a wireless communication method for a magnetic field communication network. The wireless communication method is performed by a coordinator on the magnetic field communication network. The wireless communication method includes transmitting a request signal used to request response to each of sensor nodes; selecting any one of response signals received from the sensor nodes; transmitting an acknowledgement signal to a sensor node corresponding to the response signal; selecting any one of response signals transmitted again from sensor nodes which did not receive the acknowledgement signal; and transmitting an acknowledgement signal to a sensor node corresponding to the selected response signal.
