无线传感器网络中基于时间分量的混合路由协议 Abstract WirelessSensorNetwork(WSN)technologyhasbecomeanimportantresearcharea,whichplaysasignificantroleinvariousfields,includinghealthcare,environmentmonitoring,andsurveillance.ThedevelopmentofWSNtechnologyisdirectlyrelatedtothedesignofefficientroutingprotocolsthatcopewiththeuniquecharacteristicsofthesensornetwork.Inthispaper,weproposeaTime-WeightedHybridRoutingProtocol(TWHRP)forwirelesssensornetworksthatusesacombinationofproactiveandreactiveroutingprotocols.ThisprotocolisdesignedtodealwiththeenergyconservationanddatareliabilityrequirementsofWSNs.TheTWHRPprotocolincorporatesthetimedimensionintorouteselectionanddeterminesrouteswithminimumcost,whichtakesintoaccountbothdistanceandenergyrequirements.Thesimulationresultsshowthattheproposedprotocoloutperformsotherstate-of-the-artroutingprotocolsintermsofenergyconsumptionandpacketdeliveryratio.
