POWER EFFICIENT DATA POLLING BY A WIRELESS MESH NETWORK DEVICE

원문 (중국어)

Methods and device architectures for improving the energy efficiency of end devices in a wireless mesh network. In an example, an end device of the network includes a wireless transceiver, a first processing core configured to implement a media access control layer (MAC), and a second processing core configured to implement a physical layer (PHY). The PHY operates to receive a first data poll message from the MAC and transmit the message to an external device via the wireless transceiver. The PHY further operates to receive an acknowledge message including a frame pending value. If the frame pending value indicates that the external device does not have buffered data for the end device, the PHY generates a second data poll message based on the first data poll message, including incrementing one or more of a sequence number field value, a frame counter field value, and a message integrity check field of the first data poll message, thereby enabling the MAC to remain in a low power state while the PHY transmits the second data poll message.
