Abstract: PURPOSE: A resource allocation method for a network in a ship is provided to relatively divide delay time guaranteed by each sub-class according to a buffer size required by differentiating the amount of a bandwidth. CONSTITUTION: The amount of a bandwidth allocated in each AS(Assured Service) sub-class is differentiated. Delay time guaranteed by each AS sub-class according to a requested buffer size is divided. An RIO(Random early detection with In and Out) variable value is set based on a buffer size determined according to a network topology and a ratio of the bandwidth. The size of an output link bandwidth, which is reference for access control, is set by receiving the RIO variable value.

Abstract: PURPOSE: A method for improving WiMedia network performance for a vessel network is provided to prevent and solve new DRP(Distributed Reservation Protocol) reservation collision by using a 2-hop DRP availability IE(Information Element) and a DRP control field in a vessel network environment. CONSTITUTION: A DRP target receives a 2-hop DRP availability IE from 1-hop distance devices. The 2-hop DRP availability IE includes a bitmap field which is composed of 256 bits corresponding to an MAS(Medium Access Slot) in a super frame. When DRP reservation for a 2-hop distance device is possible, the DRP target sets a bit corresponding to the MAS as 1. The DRP target sets the remaining bits as 0.

Abstract: PURPOSE: A voice phishing detection method based on distinctive weighted value learning in marine/voice communication is provided to detect voice phishing without a separate feature vector extraction process by using only a parameter extracted in a process which changes a signal into a voice signal. CONSTITUTION: An SMV(Selectable Mode Vocoder) decoder comprises a new feature vector by using a feature vector which is extracted in a process which changes an LSF(Line Spectral Frequency) into an LPC(Linear Prediction Coding); and a feature vector extracted in a process which changes the obtained LPC into a voice signal. The SMV decoder calculates likelihood for the transmitted bitstream by using a GMM(Gaussian Mixture Model) and selects a flag for a value with the maximum likelihood.

Abstract: PURPOSE: A TCP performance enhancement method in a mobile IP(Internet Protocol) packet buffering mode is provided to improve TPC performance of mobile terminal flows when a mobile terminal moves to a congested base station of a new sub-network in a smooth hand-off method. CONSTITUTION: A buffer stores packets being lost in hand-off by each mobile terminal flow. A marker marks buffered packets in the buffer as priority packets. The buffer and the marker are determined. The minimum threshold and the maximum threshold are determined in an RED buffer management method. If a variable showing the average length of queue exceeds the minimum threshold, arrival packets are discarded according to probability. If the variable reaches the maximum threshold, all the arrival packets are discarded.
