Abstract：Because ofthe frequent obstructionof direct linksbetween base stationsandwirelesssensor network（WSN） nodes，thispaperproposesastateoptimizationalgorithmforinteligentreflectingsurface（IRS）assistedumanedaerialvehicle （UAV）operation.The UAV'sflightpositionisoptimized tomaximizethefrequencybandutilizationoftheuplink.Duetothe limitednergyofUAV，thispaperintroducestheeconomiceficiency（ECE）asaperformanceevaluationindicator.Then，the relationship betweeneconomiceficiencyandthetransitionprobabilityofUAVmodesfromhovering tocruising isanalyzedto achievethegoalofoptimizingUVAworkingmodes.Anew working modeofUAVisproposedtoavoidthepoorsignal transmisionratecaused bycomplexenvironment.Incomparison withthetraditional working modeof UAV，theperformanceof itsnewworkingmodeissignficantlyimproved，whichprovidestheoreticalandpracticalsupportforsignalecoveryofWSNs. Thesimulationsshowthat，incomparisonwiththetraditionalUAVoptimizationalgorithmswithonlyasingleworkingstate，the proposedalgorithmhassignificant performanceimprovementsinmaximizing information bandwidthutilizationandECE.When thepositionortransitionprobabilityofUVAisnotintheoptimalstate，thesystembandwidthutilizationandECEarepoor， while the opposite are better.
