    摘要: A routing method comprising receiving a first packet, the first packet being broadcast for discovery of a route. A first backoff of the first packet is calculated based on a route cost of the first packet. The first packet is rebroadcast if a second packet is not received within the first backoff, the second packet being a duplicate of the first packet. A second backoff of the second packet is calculated based on a route cost of the second packet if the second packet is received within the first backoff. One of the first and the second packets is rebroadcast as a result of comparing the first backoff and the second backoff.

    摘要: After transitioning a network interface of a first wireless communication device from a low power state to an active state, transmitting a request for a second wireless communication device to transmit data for the first wireless communication device that is buffered at the second wireless communication device. An indication of whether there is data for the first wireless communication device buffered at second wireless communication device is received. When there is data for the first wireless communication device buffered at second wireless communication device, data for the first wireless communication device that was buffered at the second wireless communication device is received from the second wireless communication device.

    摘要: In a method for generating a physical layer (PHY) data unit for transmission via a communication channel, the PHY data unit is generated according to a first PHY format when the PHY data unit is to be transmitted in a regular mode, wherein the first PHY format corresponds to a first bandwidth. The PHY data unit is generated according to a second PHY format when the PHY data unit is to be transmitted in an extended range mode, wherein the second PHY format corresponds to a second bandwidth. A preamble of the PHY data unit is modulated such that a receiving device can auto-detect whether the PHY data unit was transmitted at the first bandwidth or the second bandwidth.
