Title: MEDIA ACCESS CONTROL METHOD FOR LoRa-BASED PRIVATE NETWORK OPERATION
Inventor: RYU JEONG KYU
IPC: H04W84/10
Filed: 2021-06-23
Abstract: According to the present invention, a gateway (200) and a sensor node (300) operate a base channel for basic communication (access/withdrawal/download information), and transmit sensing data through a channel allocated from the gateway (200), that is, a data channel. The gateway (200) schedules the channel occupancy time of the terminal based on the periodicity and aperiodicity of sensing data, and transmits the information to a sensor node (300). Here, the complexity of the LoRa network is allowed to be determined by a server (100) by collecting the information as the sensing data and wireless channel status information received by the gateway (200) are analyzed and transmitted to the server (100). Therefore, interference by other private LoRa networks using the same channel, which are scattered around, can be minimized, and the power consumption of the sensor node (300) can be reduced by the efficient use of data channel. As the status of the LoRa network is collected by the server (100), the use efficiency of the LoRa network using the artificial intelligence and the like can be maximized.
