文档介绍：广两帅范人学硕fj研究生学位论文在相关实验场景下对于定位算法的定位精度的提升。本文的创新工作如下:-HOP定位算法做出了比较深切探讨。本文把原有算法第三步中,对于建立的坐标距离等式集,本文不同于原有算法对等式两边平方的操作,先对各个等式做交叉相减,然后通过参数替换引入K值。利用K值相较于未知节点坐标的关系,对原有估算出的节点坐标进行了相关的修正。在做仿真实验时,本文证明了此改进算法的可行性,通过它对于原有经典算法的性能比较后,也说明了改进算法在节点定位精度方面得到的提高。,对要定位的网络首先进行区域的划分,以此来缩小定位范围。然后通过未知节点到各锚节点的跳数值的排序,得到跳数值的最小值,本文就认为此值对应的锚节点就是最临近的锚节点,随及确定了未知节点所在的划分区域。最后利用质心算法估算出未知节点的位置,从而进行定位。虽然此算法还存在不成熟性,在有些网络拓扑下不适用,但是通过实验也验证了在特定网络环境中此算法定位性能的优越性。关键字:WSN,Voronoi区域划分,节点定位,DV-workAuthor:lixinTutor:puterapplicationtechnologyDirection:Grade:workNowadays,,itswidespreadapplicationstillhasalotofeffortsneededtobemade,butnotonlyfromtheacademicresearchlevelbutalsofromspecificpracticalapplication,,involvingthesensortechnology,munication,wirelesstransmissiontechnology,puting,distributedinformationprocessingtechnology,microelectronicsmanufacturingtechniques,technologyofthesoftwareprogramming,:timesynchronizationtechnologyinWSN,workvideoinWSN,work,dynamicmanagementofWSNtechnology,researchonroutingprotocolintheWSN,congestioncontrolresearchinvolvingtheWSN,localizationofnodetechnologyinWSN,etc。Inthispaper,:smallvolume,lOWcostwhichcausedthenodeitselfsomerestrictionsonthemanufacturingdesign:thepowersupplythetotalenergy,putingandstoragecapacity,,municationshouldbeconsideredatthesametime,:Range-basedlocalizationalgorithmandtheRange——basedmethodcontaining:AOA(AngleofArrival)、TOA(TimeofArrival)、TDOA(TimedifferenceIIIofArrival)andRSSI(ReceivedSignalStrengthIndicator).RelativetotheRange-basedlocalizationalgorithm,
