¿µ¹®³»¿ë¿ä¾à The standard proposes a low power OS scheduling function reference model. It deals with the configuration of slotframes, multi-channel and a communication schedule in order for a low latency and high packet delivery ratio. It exploits group slot which dynamically assigns a scheduling slot between multi-hop away nodes based on a network topology and data traffic
