METHOD FOR IMPROVING WIMEDIA NETWORK PERFORMANCE FOR A VESSEL NETWORK, FOR SOLVING PROBLEMS WHICH CAUSE SERIOUS PERFORMANCE DEGRADATION IN A MULTI-HOP ENVIRONMENT

摘要

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.;COPYRIGHT KIPO 2013
