WI-MEDIA RESOURCE RESERVATION METHOD FOR CONSTRUCTING A WI-MEDIA NETWORK FOR A SHIP CAPABLE OF AVOIDING A COLLISION BETWEEN THE DISTRIBUTED RESERVATION PROTOCOL RESERVATIONS

摘要

PURPOSE: A wi-media resource reservation method for constructing a wi-media network is provided to reserve other links by passing through a relay device or a direct link.;CONSTITUTION: When data is transmitted and received in an MAS(medium access slot) S-R(S518), a DRP(distributed reservation protocol) IE(information element) for a reservation target node set as a reservation detail state code of a relay notification is confirmed(S522). It is determined whether the data is transmitted and received through an MAS R-T(S524). When a relay node is able to use the MAS S-R and the MAS R-T, MAS R-T information for continuously transmitting the data is stored(S526). The DRP IE set as a relay approval reservation state code is transmitted to a reservation subject node(S528).;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Start; (BB,DD,FF,HH,JJ) No; (CC,EE,GG,II,KK) Yes; (LL) End; (S510) Receiving DRP IE from a reservation subject node; (S512) Reason Code == Relay Req?; (S514) Is extra power which is necessary for relay transmission existed?; (S516) Transmitting DRP IE(Reason Code == Denied) to a reservation subject node; (S518) Is data able to be transmitted and received in an MAS S-R section of DRP IE?; (S520) Transmitting DRP IE(Reason Code=Conflict) to a reservation subject node; (S522) Confirming DRP IE of a reservation target node(Reason Code==Relay Ntf) including the same stream index; (S524) Is data able to be transmitted and received in an MAS R-T section of DRP IE?; (S526) Storing MAS R-T information for relay transmission; (S528) Transmitting DRP IE(Reason Code== Relay Accepted) to a reservation subject node; (S530) Is a reservation target node matched with DRP IE(Reason Code==Relay Accepted) transmitted to a reservation subject node?; (S532) Relaying received packets to a reservation target node according to MAS R-T information stored by receiving packets during MAS S-R; (S534) Deleting reservation information of MAS S-R and MAS R-T
