Accurate geos.atial.data are es.ential.for geographic information s.s.ems.(GIs., environmental.monitoring, and urban pl.nning. The deep integration of the open Internet and geographic information technol.gy has.l.d to increas.ng chal.enges.in the integrity and s.curity of s.atial.data. In this.paper, we cons.der abnormal.s.atial.data as.mis.ing data and focus.on abnormal.s.atial.data recovery. Exis.ing geos.atial.data recovery methods.require compl.te datas.ts.for training, res.l.ing in time-cons.ming data recovery and l.ck of general.zation. To addres. thes. is.ues. we propos. a GAIN-l.0}m-bas.d geos.atial.data recovery method (TGAIN), which cons.s.s.of two main works. (1) it us.s.a l.ng-s.ort-term recurrent neural.network (l.0}m) as.a generator to anal.ze geos.atial.temporal.data and capture its.temporal.correl.tion; (2) it cons.ructs.a compl.te TGAIN network us.ng a cue-mas.ed fus.on matrix mechanis. to obtain data that matches.the original.dis.ribution of the input data. The experimental.res.l.s.on two publ.cl. acces.ibl. datas.ts.demons.rate that our propos.d TGAIN approach s.rpas.es.four contemporary and traditional.model.0}in terms.of mean abs.l.te error (mAE), root mean s.uare error (Rms.), mean s.uare error (ms.), mean abs.l.te percentage error (mAPE), coefficient of determination (R2) and average computational.time acros. various.data mis.ing rates. Concurrentl., TGAIN exhibits.s.perior accuracy and robus.nes. in data recovery compared to exis.ing model.0} es.ecial.y when deal.ng with a high rate of mis.ing data. Our model.is.of great s.gnificance in improving the integrity of geos.atial.data and provides.data s.pport for practical.appl.cations.s.ch as.urban traffic optimization prediction and pers.nal.mobil.ty anal.s.s. © 2024 The Authors.

The s.curity of the wirel.s. s.ns.r network-Internet of Things.(Ws.-IoT) network is.more chal.enging due to its.randomnes. and s.l.-organized nature. Intrus.on detection is.one of the key methodol.gies.util.zed to ens.re the s.curity of the network. Conventional.intrus.on detection mechanis.s.have is.ues.s.ch as.higher mis.l.s.ification rates. increas.d model.compl.xity, ins.gnificant feature extraction, increas.d training time, increas.d run time compl.xity, computation overhead, fail.re to identify new attacks. increas.d energy cons.mption, and a variety of other factors.that l.mit the performance of the intrus.on s.s.em model. In this.res.arch a s.curity framework for Ws.-IoT, through a deep l.arning technique is.introduced us.ng modified Fuzzy-Adaptive Dens.Net (mF_AdaDens.Net) and is.benchmarked with datas.ts.l.ke Ns.-KDD, UNs.NB15, CIDDs.001, Edge IIoT, Bot IoT. In this. the optimal.feature s.l.ction us.ng Capturing Dingo Optimization (CDO) is.devis.d to acquire rel.vant features.by removing redundant features.
