Abstract
본 논문에서 QoS가 보장될 수 있는 IoT 망을 위한 IEEE802.15.4e TSCH(Time-Slotted Channel Hopping) 기술을 살펴보고 표준에서 다루지 않는 디바이스들 간의 협력에 의한 링크 스케줄링 방법에 대해서 제안한다. 네트워크에 조인하는 디바이스는 개선된 비콘을 스캔한다. 광고노드로부터 수신 한 개선된 비콘프레임은 디바이스들 간에직접 통신이 가능한 링크 정보를 포함하고 있으며, 새로운 디바이스는 이를 통해 자신의 채널오프셑과 타임슬롯을 결정하게 된다. 기존 단일채널 IEEE802.15.4와 본 제안을 활용한 TSCH 방식의 성능을 최대 스루풋과 최소 지연시간 관점에서 비교 분석한다.
