Zusammenfassung:	Disclosed are a device and method for task scheduling in a LoRa network. According to an embodiment of the present invention, a task scheduling method by a node device in a LoRa network includes the steps of: classifying at least one node into one of a plurality of groups; generating a frame for each group, respectively; dividing the frames for each group into a plurality of slots, respectively; allocating a logical slot index to each slot; and creating a task schedule based on the logical slot index. Therefore, it is possible to reduce a scheduling overhead, eliminate internal and external signal interference, and transmit stable and reliable data in the LoRa network. 로라 네트워크의 태스크 스케줄링 장치 및 방법이 개시된다. 본 발명의 실시 예에 따른 로라 네트워크의 노드 장치에 의한 태스크 스케줄링 방법은, 적어도 하나의 노드를 복수의 그룹들 중 하나로 분류하는 단계와, 각 그룹들 각각에 대한 대한 그룹별 프레임을 생성하는 단계와, 그룹별 프레임들 각각을 복수의 슬롯으로 분할하는 단계와, 각 슬롯에 논리 슬롯 인덱스를 할당하는 단계 및 논리 슬롯 인덱스를 기반으로 태스크 스케줄을 생성하는 단계를 포함할 수 있다.
