摘要WSNs安全协议分析设计摘要无线传感器网络是一套由微型廉价的传感器节点利用无线通信方式构成的自组织网络系统。在无线传感器网络中，传感器节点的安全将直接影响整个网络的安全性和可用性。所以，本文采用NS-2仿真平台针对恶意节点对经典的分簇路由协议算法进行仿真分析，在还原该算法的基础上，掌握设计理论及编程经验，将高效、安全的路由协议应用于实践，来解决实际问题，从而改善应用系统的性能、节约能耗等，这对于工业生产与科技创新具有重大意义。论文要求对无线传感器网络的节点特性、遭受的攻击种类及防御措施进行详细阐述，重点对路由协议进行研究，选取LEACH协议对其进行深入探讨和仿真，特别针对恶意节点对现有改进算法在安全方面进行分析。基于LEACH路由协议，通过增加对恶意节点的检测技术，引进更为安全的路由策略——SE-LEACH，在对该策略进行设计后给出了详细的分析报告，体现改进算法在安全性能优化、能量利用率和延缓网络生存周期上的突出表现。关键词：无线传感器网络；分簇；LEACH；安全检测AbstractTheAnalysisandDesignofWSNsSecurityProtocolAbstractWirelesssensornetwork(WSN)isasetoftheminiatureofcheapsensornodesbywirelesscommunicationmodeofself-organizingnetworksystem.Inwirelesssensornetworks,thesafetyofthesensornodeswilldirectlyaffectthesafetyandavailabilityoftheentirenetwork.So,thisarticleusestheNS-2simulationplatformagainstmaliciousnodesontheclassicalclusteringroutingprotocolalgorithmsimulationanalysis,thereductiononthebasisofthealgorithm,masterthedesigntheoryandprogrammingexperience,efficientandsecureroutingprotocolwasappliedtopractice,tosolvepracticalproblems,soastoimprovetheperformanceoftheapplicationsystem,savingenergyconsumption,etc.,fortheindustrialproductionandscientificandtechnologicalinnovationisofgreatsignificance.Paperrequirementsofwirelesssensornetworknodecharacteristics,typeofattackanddefensemeasuresindetail,studiesthekeyrightbytheagreement,selectLEACHagreementtoin-depthstudyandsimulation,especiallyformaliciousnodetotheexistingalgorithmisanalyzedintermsofsecurity.BasedonLEACHroutingprotocol,byincreasingthedetectingtechnologyofmaliciousnodes,introducemoresafety-SE-LEACHroutingstrategy,strategyonthedesignisgivenafterdetailedanalysis,reflectstheimprovedalgorithminsafetyperformanceoptimization,energyutilizationanddelaytheoutstandingperformanceofthenetworklifecycle.Keywords:wirelesssensornetworks(WSNs);clustering;LEACH;safetyinspection目录PAGE\*MERGEFORMATIIITOC\o"1-3"\h\z\uHYPERLINK\l"_Toc389159463"第1章绪论PAGEREF_Toc389159463\h1HYPERLINK\l"_Toc389159464"1.1课题研究背景及意义PAGEREF_Toc389
