    • 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.
    • 提供了一种用于控制自组织网络中的节点的拥塞的方法和装置,包括:将信道状态分类为忙信道状态和空闲信道状态,然后监视信道状态; 当在监视信道状态期间存在要发送的数据时,执行与相邻节点获取信道的竞争; 在赢得竞争时基于渠道状态计算可用带宽; 以及基于可用带宽确定要发送的数据量。 ah-hoc网络中的节点监控其自身的无线信道状态,以获得信道争用信息,从信道争用信息中计算可用带宽,并根据可用带宽控制传输量。 因此,节点可以避免超过信道容量的超量业务。 频道争用是网络性能下降最直接和最重要的原因,可以放宽。

    • 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.
    • 用户兴趣模式建模服务器包括历史收集单元,关键字提取单元,时间模式提取单元,关键字扩展单元,时间模式分析单元和模式建模单元。 历史收集单元收集用户对内容的使用历史。 关键词提取单元从内容的使用历史中提取关键词。 时间模式提取单元提取该关键字的第一时间模式。 关键词扩展单元通过搜索关键词的相关单词提取扩展关键字。 时间模式分析单元基于第一时间模式分析扩展关键字的第二时间模式。 模式建模单元基于第一和第二时间模式来模拟关键字和扩展关键字的用户兴趣模式。
