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: An effective resource allocation method of a network in a ship is provided to maximize service acceptance capacity by guaranteeing QoS(Quality of Service) for an AS(Assured Service) for network in the ship. CONSTITUTION: An access control process is executed for a flow, which passes through a differentiated service router, for an AS sub-class including a random over-provisioning factor. An adaptive RIO(Random early detection with In and Out) buffer management method, which sets variable values of an RIO method, is executed by considering an in-profile packet and the whole packet based on a buffer size. The buffer size is determined according to a bandwidth ratio allocated to the AS sub-class and a network topology.
