Abstract: PURPOSE: A network service quality guarantee method in a ship is provided to set variables of RIO(RED(Random Early Detection) with In and Out) again by considering the maximum rate of the whole packets in fixed time sections. CONSTITUTION: A buffer size is determined by being allocated according to a network topology and an AS(Assured Service) sub-class. The variable values of the RIO are set by considering the whole packets and profile packets based on the determined buffer size in fixed time sections. When the profile packets and the whole packets are arrived, the number of the profile packets is determined in the fixed time sections according to the number of the whole packets.

Abstract: Disclosed is a method for analyzing the performance of a physical layer network coded system in a nakagami fading channel. The method analyzes the performance of a bidirectional relay system to which a physical layer network coding is applied and an average final symbol error rate in the nakagami fading channel. The present invention induces the upper limit of the average final symbol error rate with a closed formula by inducing the character of a gamma random variable which shows a probability character of the nakagami fading channel and applying the upper limit for a Gaussian function.

Abstract: Disclosed is a high-speed vertical handover method in a MIH and PFMIPv6 environment. The method enables a corresponding feature via an MIH message without altering a link layer. In other words, a report massage is transmitted to a corresponding terminal′s MIHF, and the MIHF which received the message transmits a MIH_MN_HIrequest which is a network-layer message notifying the initiation of a handover to a PreviousMAG instead of a Handover initiation which is a conventional link-layer message notifying the initiation of a handover.

Abstract: PURPOSE: An entropy coding method of a compressed specific parameter for distribution voice recognition in marine environment is provided to add and transmit 10.07 bits as an error prevention bit, thereby preventing performance degradation of a distribution voice recognition system caused by packet loss during communication of the marine environment. CONSTITUTION: A distribution voice recognition system quantizes an MFCC(Mel Frequency Cepstral Coefficient) and log energy extracted in a corresponding frame. The distribution voice recognition system additionally compresses a sub-vector index of the MFCC and indexes of C0 and log-E sub-vector by using a Huffman table corresponding to voice classification of the frame. The system calculates differential information for the compressed index. The system applies differential Huffman coding to the differential information.
