    • A communication method between nodes that have their own timers and have an equal start time of a frame for Time Division Multiple Access (TDMA) communication based on their timers in a mobile ad-hoc network, in which a node receives a timer value derived by a neighbor node on the basis of a transmission time, from the neighbor node, the node calculates a time offset indicative of a difference between a timer value derived on the basis of a time the node received the timer value, and the received timer value, and stores the time offset in a memory, and upon receiving a time value indicating a time related to inter-node TDMA communication from the neighbor node, the node corrects the received time value as a time value based on its timer using the time offset, and performs TDMA communication using the corrected time value.

    • Disclosed a system and method for mutual authentication between a node and a sink in a sensor network. At least one sink periodically creates a neighboring sink list including information on at least one adjacent sink, and the sink requests node authentication to a base station when receiving an authentication request from the node and transmits its own neighboring sink list to the node when the node authentication has been completed. When the node moves and requests authentication to another sink, the another sink stores a neighboring sink list received from the node, determines if a node-authenticable sink exists in its own neighboring sink list according to the authentication request, and requests re-authentication of the node to the node-authenticable sink when the node-authenticable sink exists, so that re-authentication between the node and the sink is easily performed.

    • A method for transmitting/receiving data with transfer obligation delegated in a Wireless Sensor Network (WSN) reduces the time and power spent by a transmitting apparatus to wait for acknowledgment that a data transfer was successful. The method for transmitting data from a transmitting end to a receiving end through a set transfer route by multiple data transmit/receive apparatuses provided in a Wireless Sensor Network (WSN), typically includes the steps of: performing temporary storage of data to be transmitted on receiving a request to transmit data; requesting a data transmit/receive apparatus, existing on a next route, to transmit data while transmitting data to a data transmit/receive apparatus which is set as a transfer route; and confirming the delivery of the data to the data transmit/receive apparatus set as the transfer route, and then deleting the temporarily stored data frame.
    • 在无线传感器网络(WSN)中委托的传输义务发送/接收数据的方法减少了发送装置花费的时间和功率,以等待确认数据传输成功。 通过在无线传感器网络(WSN)中提供的多个数据发送/接收装置通过设置的传输路由从发送端向接收端发送数据的方法通常包括以下步骤:执行临时存储要发送的数据 接收传送数据的请求; 请求在下一个路由上存在的数据发送/接收装置在将数据发送到被设置为传送路由的数据发送/接收装置的同时发送数据; 并确认将数据传送到设置为传送路由的数据发送/接收装置,然后删除临时存储的数据帧。

    • In a system and method for detecting network intrusion, the system comprises: a packet capturer which captures at least one packet on a network; a preprocessor which provides feature values dependent on features of each packet captured by the packet capturer; and a learning engine for classifying patterns dependent on the feature values provided by the preprocessor into two different pattern sets, and for selecting one pattern set having more elements from the pattern sets as a reference set so as to detect network intrusion. The network intrusion detection system and method do not depend on historical data according to known attack patterns, and thus not only detect a changed attack pattern but also efficiently detect network intrusion.
