Abstract
Systems and methods are provided for maintaining a low power endpoint (LPE) synchronized on a time synchronized channel hopping network (TSCH). An LPE receives a guaranteed time slot (GTS) from a parent node. The LPE determines a wake-up time that coincides with or is prior to the GTS. The LPE enters a low power mode to conserve power until the wake-up time occurs. At that time, the LPE enters a regular power mode and may communicate with the parent node.
