建構多樣化目的之無線感測網路實測環境Reporter:SunChung-YuehHSCCLaboratory,NationalCentralUniversity.1AdaptiveWirelessSensorNetwoAbstract建構基於802.15.4

協定下之無線感測網路(WirelessSensorNetwork)，可以讓使用者透過Web

介面，來使用實體感測網路環境，進行線上實驗與驗證。以有線網路為骨幹，經由網路交換器(Switch)，連結中央伺服器、控制伺服器與所有節點，所有節點經RS232toTCP/IPConverter，交由控制伺服器執行監測與通訊，並將資訊寫回MySQL資料庫。可連接不同感測硬體裝置(MicaMotes

/Octopus)，進行偵測狀態(StatusDetecting)、程式更新(Re-programming)、與資料蒐集與整合(DataCollection&Aggregation)等實驗。2Abstract建構基於802.15.4協定下之無線感OutlineIntroductionMotivationRelatedWorkArchitectureImplementationApplicationExampleConclusionandFutureWork3OutlineIntroduction3IntroductionWirelessSensorNetworkissues:FaultToleranceScalabilitySensorCostsHardwareConstraintsTransmissionMediaEnvironmentSensorNetworkTopologyPowerConsumption4IntroductionWirelessSensorNeIntroduction(cont.)Theresearcherneed:Setup
