  • Publication number: 20040228293
    Abstract: A method for enhanced power saving on DCF based wireless networks is disclosed. The method divides a beacon transmitting section in an Announcement Traffic Indication Message (hereinafter, referred to as “ATIM”) window period defined by IEEE standard 802.11 according as there is a data packet to be sent or not and allows a terminal that has received the beacon to go to a doze state immediately according to beacon reception timing, thereby preventing unnecessary power consumption.

  • Publication number: 20040229622
    Abstract: A method for power saving routing in wireless networks is disclosed. The present invention calculates a distance to a destination node to select and estimate candidate nodes so as to reduce the amount of calculations in the event of routing. Furthermore, the invention repeats the algorithm by optimum value n so that accessibility to the destination node can be obtained. This enables more efficient routing.

  • Publication number: 20040068381
    Abstract: A method of handling a database for bioinformatics is disclosed. A server receives a sequence to be compared and analyzed from the user terminal to store it in a queue. When there exist other sequences to be compared and analyzed, the server reads the sequence of the current order from the database to compare it with all of sequences stored in the queue. That is, the server accesses the database once to use it for all of user requests currently being processed. Because the server accesses the database only once for each user request, the average system cost and response time are decreased. Furthermore, the threshold of the user request arrival rate that can be received on the same hardware in the present invention is higher compared to the convention method, so that larger amount of users can be provided the comparison/analysis service.
