Background MobileAdHocNetworks(MANETs)arecomposedofmobiledevicesthatcommunicatewitheachotherwithouttheneedforafixedinfrastructure.Thesenetworksaredynamicandchangefrequently,makingtraditionalroutingprotocolsunsuitableforsuchscenarios.SeveralroutingprotocolshavebeenproposedforMANETs,includingproactive,reactive,andhybridroutingprotocols. Inproactiveprotocols,everynodemaintainsacompleteandup-to-dateroutingtablefortheentirenetwork.ThisapproachisnotscalableinMANETsbecauseofthelimitedresourcesandfrequenttopologychanges.Reactiveprotocols,ontheotherhand,discoverroutesonlywhenneededand,therefore,reducetheoverheadofmaintainingroutingtables.However,reac
