摘要： Provided is a method and apparatus for controlling congestion of a node in an ad-hoc network comprising: classifying a channel state into a busy channel state and an idle channel state and then monitoring the channel state; performing contention for acquiring a channel with neighboring nodes when data to be transmitted is present during the monitoring of the channel state; calculating an available bandwidth on the basis of the channel state when wins the contention; and determining the amount of data to be transmitted on the basis of the available bandwidth. The nodes in the ah-hoc network monitor their own wireless channel state so as to obtain channel contention information, calculate an available bandwidth from the channel contention information, and control a transmission amount on the basis of the available bandwidth. Accordingly, the nodes can avoid excessive traffic which exceeds channel capacity. Channel contention, which is the most immediate and important cause of a decrease in network performance, can be loosened.

摘要： A method and apparatus for predicting video traffic are provided. The method includes extracting the statistical properties of previous Moving Picture Experts Group (MPEG)-4 video traffic and predicting the size of a subsequent frame based on the statistical properties of the previous MPEG-4 video traffic. Therefore, it is possible to address such problems associated with traffic bursts as transmission delays or low throughputs and thus to improve the performance of communication and network systems that transmit video traffic.
摘要翻译：提供了一种用于预测视频流量的方法和装置。该方法包括提取先前运动图像专家组（MPEG）-4视频业务的统计特性，并且基于先前的MPEG-4视频业务的统计特性来预测后续帧的大小。因此，可以将与业务突发相关联的问题解决为传输延迟或低吞吐量，从而提高传输视频流量的通信和网络系统的性能。
