    摘要: A multi-channel scheduling method in a wireless network is provided. The wireless network includes a plurality of Wireless Local Area Network (WLAN) device with a single radio interface. A regular time interval P and a Channel Coordination Window (CCW) to be repeated in a period of P are set. A request is made such that the plurality of devices are tuned to a first channel at a start point of the CCW. A pair of arbitrary WLAN devices among the plurality of WLAN devices is allowed to transmit control frames in the regular time interval P. The control frames are a transmission proposal control frame for proposing communication in a second channel and a response frame, responding to the transmission proposal control frame, for indicating whether the second channel has been accepted or rejected. The arbitrary WLAN device of the pair are switched to the second channel after acceptance.

    摘要: An apparatus and a method are provided in a wireless local area network mesh communication system having one wireless interface and multi-channels for improving the performance of the WLAN mesh communication system. A transmitter and a receiver are set to use different channels respectively. A first channel is assigned as a dedicated channel for transmitting data frames and a second channel is assigned as a common channel which receives a control frame, while transmitting the data frames through the first channel. Thus, the control frame is received, while transmitting the data frames, to obtain information relating to the channels which are not already in use and to effectively use the channels, thereby improving the capacity of the network.

    摘要: A system and method for controlling congestion using Request-to-Send (RTS) and Clear-to-Send (CTS) in a wireless mesh network are provided. A receiver in a congestion state sets a duration field value of congestion control in a CTS frame and transmits the CTS frame to a sender. In response, the sender retransmits an RTS frame to the receiver without transmitting data, after waiting for an RTS retransmission waiting time period corresponding to the duration field value. The congestion state information is broadcast to neighboring nodes. Therefore, the congestion control system using the CTS frame does not use a separate frame for the congestion control. And, all of the neighboring nodes can participate in the congestion control, increasing the network efficiency.
