Abstract: A host assembly is communicatively coupled to a wireless device assembly via a first interface and via a second interface. A first signal is received at the wireless device assembly from the host assembly. The first signal indicates a request for the wireless device assembly to enter a host sleep mode of operation. In response to receiving the first signal, the wireless device assembly transmits a third signal to the host assembly, wherein the third signal indicates entry into the host sleep mode of operation. Subsequent to transmitting the third signal to the host assembly via the first interface, the wireless device assembly enters into the host sleep mode of operation. While in the host sleep mode of operation, the wireless device assembly transmits, via the second interface, the second signal, and, after transmitting the second signal to the host assembly, exits the host sleep mode of operation.

Abstract: A wireless network device comprises a forwarding table and a mesh routing module. The forwarding table stores direct and reverse entries, each including a destination address, a next hop address, and a metric. The metric of the direct entries corresponds to a route from the wireless network device to the destination address. The metric of the reverse entries corresponds to a route from the destination address to the wireless network device. The mesh routing module wirelessly receives route discovery packets and creates corresponding entries in the forwarding table.
