Energy efficient discovery and traffic management in a mesh WAN for IoEs with a wakeup receiver
A relay device in a mesh wireless access network (WAN) may listen for a signal during a pre-wakeup (PWU) period to determine whether to power on a radio during a wakeup cycle. If the relay device receives a signal during the PWU period, it may power on a radio to transmit a discovery broadcast or to send and receive data. The relay device may also receive synchronization signals during the PWU period to maintain timing synchronization in cases when the wakeup cycle includes long periods of inactivity. That is, different internet of everything (IoE) devices (including relay devices) may operate in different discovery modes based on different mobility patterns. Devices that move frequently may operate in a transient operating mode. Devices that rarely move may operate in a persistent operating mode, and may take advantage of the PWU synchronization signals.
