[0030] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0031] The present invention is mainly a resource allocation algorithm executed on the AP, and the implementation of the present invention will be described in detail below in conjunction with examples.
[0032] AP maintains the relevant information of each video user through the structure linked list Video_info, and the main variables of each structure include:
[0033] addr: This variable is used for the address of the video user, which is unique in the entire network;
[0034] average_bitrate: This variable is used to store the average bit rate of the video downloaded by the video user data;
[0035] buffer_state: This variable is used to store the buffer status information fed back by the video user through the ACK frame last time;
[0036] play_state: This variable is used to store the playback status information fed back by the user through the ...
