Abstract
A network using a routing protocol for low-power and lossy networks ('RPL') can provide timing information for a next destination oriented directed acyclic graph ('DODAG') information object (“DIO”) packet by including DIO timing information in an RPL packet or a beacon. When a low energy node receives the RPL packet, it may use the DIO timing information to determine a wake time which corresponds to the timing of the next DIO packet. The low energy node may enter a sleep state after determining the wake time and remain in the sleep state until the wake time when it enters an active state and listens for the next DIO packet. Alternatively, DIO slots in a DIO slot frame may be allocated for communicating DIO packets.
