Abstract: A user interest pattern modeling server includes a history collection unit, a keyword extraction unit, a time pattern extraction unit, a keyword extension unit, a time pattern analysis unit and a pattern modeling unit. The history collection unit collects a user's use history of a content. The keyword extraction unit extracts a keyword from the use history of the content. The time pattern extraction unit extracts a first time pattern of the keyword. The keyword extension unit extracts an extended keyword through searching related words of the keyword. The time pattern analysis unit analyzes a second time pattern of the extended keyword based on the first time pattern. The pattern modeling unit models a user interest pattern for the keyword and the extended keyword based on the first and second time patterns.

Abstract: 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.

Abstract: 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.
