Abstract:
A channel reservation-based media access control method according to an embodiment of the present invention includes: a step that a reception node wakes up according to a predetermined period and transmits a wake-up signal to a transmission node; a step that the transmission node transmits channel information to the reception node when the transmission node receives the wake-up signal from the reception node; a step that the reception node selects a reserved channel for transmitting and receiving data in the next transmission and reception period based on the received channel information and channel information of the reception node when the reception node receives the channel information from the transmission node and transmits the selected reserved channel information to the transmission node; a step that the transmission node receives the reserved channel information from the reception node and transmits data to the reserved channel in the next transmission and reception period; and a step that the reception node receives the data from the transmission node through the selected reserved channel. [Reference numerals] (AA) Node 1; (BB) Node 2; (CC) Node 3; (DD,FF) Generating a data packet; (EE) Channel information (CI); (GG) RC of the next data packet; (HH) Reception; (II) Transmission; (JJ) Use status
