摘要:
Magnetic field communication methods and apparatuses are performed by the coordinator and node of a magnetic field area network, respectively. The method which is performed by the coordinator includes: (a) sending a request packet requesting association with a network, disassociation from a network, network association state checking, data transmission, or group address setting, (b) receiving response packets, (c) selecting one or more response packets from among the received response packets, (d) sending a response acknowledgement packet to nodes corresponding to the selected response packets, (e) receiving response packets resent by nodes which have not received the sent response acknowledgement packet, (f) selecting one or more response packets from among the response packets received at (e), and (g) sending a response acknowledgement packet to nodes corresponding to the response packets selected at (f).
