Summary:Disclosed are a gateway and a sensor node communicating with each other in a wireless sensor network. According to an embodiment of the present invention, the gateway transmits answer data, generated based on schedule information of a previous uplink section, and schedule information of a next uplink section to a plurality of sensor nodes. The sensor nodes transmits data based on the answer data and the schedule information of the next uplink section. 무선 센서 네트워크에서 상호 통신하는 게이트웨이 및 센서 노드가 개시된다. 실시예에 따른 게이트웨이는 이전 업링크 구간의 스케쥴 정보에 기초하여 생성된 응답 데이터와 다음 업링크 구간의 스케쥴 정보를 복수의 센서 노드들에게 전송한다. 실시예에 따른 센서 노드는 응답 데이터 및 다음 업링크 구간의 스케쥴 정보에 기초하여 데이터를 전송한다.
