Abstract:
A network device may include first and second processors and a wireless transceiver under control of the second processor. The network device may further maintain one or more signatures and a wake-up module executable by the second processor. The wake up module may receive a multicast wireless communication while the first processor is in a low-power sleep mode. The wake up module may determine whether a data portion of the multicast wireless communication includes a signature. If the data portion of the wireless communication includes the signature, the wake up module may cause the first processor to leave the low-power sleep mode and process the multicast wireless communication.
