A Class B of LoRaWAN communicates by activating a device by allocating a ping slot during a beacon communication period at the gateway. At this time, the device switches to the reception mode at the allocated time. However, when there is no data to be transmitted, the device switched to the reception mode consumes meaningless time and energy. Therefore, this paper proposes a scheduling technique that allows the next device to send a message at that time by arbitrarily dividing the beacons period by 1/2 (64 seconds) from the time when the device is switched into receiving mode due to Ping Slot. |
