Provided is a method and apparatus for wirelessly transmitting Universal Serial Bus (USB) application data by using an Enhanced Distributed Channel Access (EDCA) scheme that uses one or more Access Channels (ACs) having different priorities. The method includes receiving one or more USB application data from an USB application, dynamically assigning an AC through which the USB application data is to be transmitted, and transmitting the USB application data through the assigned AC.

Scheme for supporting wireless transmission taking into account QoS of USB application data

The present disclosure provides a method for managing buffers of a device for Universal Serial Bus (USB) communication in a wireless environment. The method includes determining respective current data storage levels of transmit buffers that store different types of data for USB communication; comparing the respective current data storage levels of the transmit buffers with corresponding respective predetermined threshold levels; and controlling an input rate or output rate of a first transmit buffer if it is determined based on the comparison that the first transmit buffer has a current data storage level that exceeds a predetermined threshold level.

Buffer management method and apparatus for universal serial bus communication in wireless environment

The present invention relates to a method for cluster based data in wireless sensor networks. The method includes: selecting any one of border nodes positioned at the edge of a cluster as a temporary cluster head as a temporary cluster head when a target is sensed in the cluster; bugging data of the temporary cluster head by border nodes in other adjacent cluster which do not sense the target to temporarily change the border node selected as the temporary cluster head to a cluster head of each of the border nodes; when the target is sensed by at least one of the border nodes, collecting data from each of the border nodes by the temporary cluster head to transferring the collected data to an actual cluster head of the temporary cluster head; and aggregating the collected data by actual cluster head of the temporary cluster head.
