Abstract: PURPOSE: A benchmark device for comparison evaluation of an internet application traffic classification method is provided to supply an accurate network traffic analyzing result. CONSTITUTION: A user interface(1) inputs internet application traffic trace data of a user. The user interface provides operation data operated from performance evaluation and classification results of an internet application traffic classification method. A pre/post-processor(3) converts the input data into a form suitable for each classification plug-in. The pre/post-processor compares and evaluates the performance about each plug-in. A classifier(5) manages/executes plug-in.

Abstract: PURPOSE: By putting in tune the necessary delay to decide the translation distance and receiving node of data packet data communications method and system of the duty cycle wireless sensor network select the most favorable node. CONSTITUTION: A source node having transmission data packet consecutively transmits a message a plurality of preambles shorting than the operational range of the receiving node. The receiving node receiving a message preamble transmits an acknowledge(ACK) to the source node. The source node receives a message ACK. Compensation is presently calculated of the case of transmitting data packet with the receiving node. The prediction compensation of the case of not transmitting data packet with the receiving node and waiting the other receiving node is calculated.
