DTN中动态散发等待路由及拥塞控制策略研究的开题报告Introduction:DTN(DelayTolerantNetwork)isatypeofnetworkthatdoesnotrequirecontinuousconnectivitybetweennodes.InDTN,communicationoccursthroughaseriesoftemporaryconnectionsbetweennodes,whichmaybeinterruptedduetodelay,mobility,congestionorotherfactors.TheroutingprotocoliscriticalinDTNbecauseitdeterminesthebestpathfordatatransmissionbetweennodes.DynamicBroadcastingandWaitingRouting(DBWR)andCongestionControlaretwoimportantaspectsofDTNrouting.DBWRmethodisusedtobroadcastmessagesfromonenodetoanotherinadynamicway,wheretheforwardingnodewaitsforacertainperiodbeforepassingthemessagetothenextnode.CongestionControlisusedtoavoidthecongestionofdatapacketsinthenetworkbyregulatingtheflowofdatabetweennodes.Objectives:ThemainobjectiveofthisresearchistoproposeanewDBWRandCongestionControlstrategyforDTNtoimprovetheperformanceofdatatransmission.Specificobjectivesinclude:1.Investigatethestate-of-the-artresearchonDTNroutingprotocols,particularlyonDBWRandCongestionControlstrategy.2.AnalyzethecurrentshortcomingsoftheexistingDBWRandCongestionControlmechanismsinDTN.3.ProposeanewDBWRandCongestionControlstrategybasedonreal-worldnetworksituationsandevaluateitsperformancethroughsimulations.4.ComparetheproposedstrategywithexistingDTNroutingprotocolsbasedonperformancemetricssuchaspacketdeliveryratio,end-to-enddelay,andnetworkoverhead.Methodology:Toachievetheaforementionedobjectives,theresearchwillbeconductedinthreephases:Phase1:Literaturereviewandproblemanalysis.ThisphasewillinvolveanextensivereviewoftheliteratureonDTNroutingprotocols,particularlyonDBWRandCongestionControl.Theanalysiswillidentifythecurrentshortcomingsoftheexistingstrategiesandprovideabenchmarkfortheproposedstrategy.Phase2:Designandimplementationoftheproposedstrategy.Basedontheanalysisoftheexistingmechanisms,anewDBWRandCongestionControlstrategywillbedesigned,takingintoconsiderationreal-worldnetworksituations.Theproposedstrategywillbeimplementedinasimulationenvironmenttoevaluateitsperformance.Phas
