Abstract: PURPOSE: A fairness improving method is provided to improve link usage rates by improving fairness between TCP(Transmission Control Protocol) flows in a single domain and a multi-domain environment. CONSTITUTION: The yield fairness of an individual flow is improved in an integrated traffic management method in a differentiated service for a network in a ship. A TCP user uses AS(Assured Service) without managing user flows. The yield and the link usage rate are improved in a minimum bandwidth, a surplus bandwidth, and bandwidth shortage. The improvement of the yield fairness and the link use rate is confirmed in the improved single domain environment and the multi-domain environment.

Abstract: PURPOSE: A cooperative transmission method strong against frequency selective fading is provided to obtain a cooperative diversity gain through asynchronous cooperative communication in a frequency selective fading channel. CONSTITUTION: A source node(S) transmits a generated OFDM(Orthogonal Frequency Division Multiplexing) transmission symbol to relay nodes(R1,R2) respectively. Each relay node performs an amplification operation to the received symbol. A destination node(D) performs a cyclic prefix removal to the symbol received through each of the relay nodes. The destination node obtains an estimation value of combination symbols transmitted from the source node. The destination node demodulates actual data symbols through a recombination process by using the estimation value of the combination symbols.

The size of an output link bandwidth, which is reference for access control, is set by receiving the RIO variable value.
