Title:EnvironmentallyAdaptiveFiberOpticSensorNetworkSelf-HealingMethod
Abstract:
Fiberopticsensornetworksplayacriticalroleinvariousapplications,suchasstructuralhealthmonitoringandenvironmentalsensing.However,thesenetworksarevulnerabletovariousenvironmentalfactors,suchasphysicaldamage,temperaturechanges,andsignalinterference.Toensurethereliabilityandeffectivenessofthesensornetwork,aself-healingmethodthatcanadapttotheenvironmentisnecessary.Thispaperpresentsacomprehensiveoverviewofenvironmentallyadaptivefiberopticsensornetworkself-healingmethods,includingfaultdetection,faultlocalization,andfaultrecoverytechniques.Furthermore,wediscussthechallengesandfutureresearchdirectionsinthisfield.
Introduction:
Fiberopticsensornetworkshavegainedsignificantattentionduetotheiruniqueadvantages,suchashighsensitivity,immunitytoelectromagneticinterference,anddistributedsensingcapability.However,thedeploymentofthesenetworksinharshanddynamicenvironmentsposeschallengestotheirlong-termreliability.Environmentalfactorssuchasphysicaldamage,temperaturevariations,andexternalperturbationscanleadtofiberbreakage,signalloss,orperformancedegradation.Inresponsetothesechallenges,developingaself-healingmechanismthatcanadapttotheenvironmentbecomescrucial.
