COOPERATIVE MAC PROTOCOL COMMUNICATION METHOD BY VISIBLE LIGHT COMMUNICATION

摘要

PURPOSE: A cooperative MAC protocol communication method for a visible light communication is provided to improve a communication speed and communication quality between a transmit node and a receive node in a visible light communication. CONSTITUTION: A transmission node (100) transmits an optical signal through visible light which is illumination light. A relay node (200) includes a receive unit receiving the optical signal and an emit unit emitting the optical signal. A receiver node (300) receives the optical from the relay node. The transmission node or the receiver node selects the relay node with which the transmission node or the receive node communicates, among a plurality of relay nodes. The transmission node and the receiver node select the relay node to be used for data transmission.
