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.

1. A wireless communication method for a magnetic field communication network, the wireless communication method being performed by a coordinator on the magnetic field communication network, the wireless communication method comprising:
(a) transmitting to a plurality of sensor nodes a request signal to request a response from each of the plurality of sensor nodes; (b) selecting any one of a plurality of response signals received from the plurality of sensor nodes; (c) transmitting an acknowledgement signal to a sensor node corresponding to the response signal selected at (b); (d) selecting any one of response signals transmitted again from remaining sensor nodes, among the plurality of sensor nodes, which did not receive the acknowledgement signal at (c); and (e) transmitting an acknowledgement signal to a sensor node corresponding to the response signal selected at (d), wherein in (d), the response signals are transmitted again from the remaining sensor nodes to the coordinator even when there is no additional request signal from the coordinator to the remaining sensor nodes to request a response from the remaining sensor nodes.
