Method and apparatus for transmitting video streams in wifi mesh networks

A method for transmitting multiple video streams in an access point in a WiFi mesh network, wherein, the method includes:

• creating, for the multiple video streams that are received, multiple video queues at the application layer, wherein each video queue contains one of the multiple video streams;
• determining, for each video queue, the weight of the video queue according to link related information corresponding to the video stream contained in the video queue;
• transmitting the multiple video streams from the application layer to the MAC layer according to the weight corresponding to each video queue, in order to transmit the multiple video streams to the corresponding node.

A first apparatus for transmitting multicast videos in an access point in a WiFi mesh network, wherein, the first apparatus includes:

• means for receiving a video stream and determining the node(s) to which the video stream needs to be transmitted, wherein the video stream includes a multicast address;
• means for determining dynamically a transmission mode of the video stream and transmitting corresponding video stream to multiple stations using the transmission mode when the nodes are the multiple stations corresponding to the multicast address;
• means for transmitting corresponding video stream to a next access point using unicast mode when the node is the next access point.

A second apparatus for transmitting video streams in an access point in a WiFi mesh network, wherein, the second apparatus includes:

• means for creating, for multiple video streams that are received, multiple video queues at the application layer, wherein each video queue contains one of the multiple video streams;
• means for determining, for each video queue, the weight of the video queue according to link related information corresponding to the video stream contained in the video queue;
• means for transmitting the multiple video streams from the application layer to the MAC layer according to the weight corresponding to each video queue, in order to transmit the multiple video streams to the corresponding node.
