Ad hoc network, ib tus kheej npajmesh network, originates los ntawm Mobile Ad Hoc Networking, los yog MANET luv luv.
"Ad Hoc" los ntawm Latin thiab txhais tau tias "Rau lub hom phiaj tshwj xeeb nkaus xwb", uas yog, "rau lub hom phiaj tshwj xeeb, ib ntus".Ad Hoc network yog ntau lub hop ib ntus kev tswj tus kheej lub network tsim los ntawm ib pawg ntawm cov xov tooj ntawm tes nrogwireless transceivers, tsis muaj chaw tswj lossis chaw sib txuas lus yooj yim.Tag nrho cov nodes hauv Ad Hoc network muaj cov xwm txheej sib npaug, yog li tsis tas yuav muaj qhov chaw nruab nrab los tswj thiab tswj lub network.Yog li ntawd, kev puas tsuaj rau ib lub davhlau ya nyob twg yuav tsis cuam tshuam rau kev sib txuas lus ntawm tag nrho lub network.Txhua node tsis tsuas yog muaj lub luag haujlwm ntawm lub davhlau ya nyob twg tab sis tseem xa cov ntaub ntawv rau lwm cov nodes.Thaum qhov kev ncua deb ntawm ob lub node ntau dua qhov kev ncua deb ntawm kev sib txuas lus ncaj qha, lub nruab nrab ntawm cov ntaub ntawv xa mus rau lawv kom ua tiav kev sib txuas lus.Qee lub sij hawm qhov kev ncua deb ntawm ob lub node nyob deb dhau lawm, thiab cov ntaub ntawv yuav tsum tau xa mus los ntawm ntau lub nodes kom mus txog qhov chaw ntawm qhov chaw.
Qhov zoo ntawm wireless ad hoc network technology
IWAVEWireless ad hoc network kev sib txuas lus muaj cov yam ntxwv hauv qab no nrog nws txoj kev sib txuas lus yooj yim thiab muaj peev xwm sib kis tau zoo:
●Kev tsim kho network nrawm thiab hloov tau yooj yim network
Nyob rau ntawm qhov chaw ntawm kev ua kom muaj zog, nws tsis yog txwv los ntawm kev xa tawm cov chaw txhawb nqa xws li chav khoos phis tawj thiab cov khoom siv kho qhov muag.Tsis tas yuav khawb trenches, khawb phab ntsa, lossis khiav cov kav dej thiab xaim.Kev tsim kho kev nqis peev yog me me, qhov nyuaj yog qhov tsawg, thiab lub voj voog luv luv.Nws tuaj yeem siv tau thiab ntsia tau yooj yim hauv ntau txoj hauv kev hauv tsev thiab sab nraum zoov kom ua tiav kev tsim kho network sai yam tsis muaj chav khoos phis tawj thiab tus nqi qis.Centerless faib network txhawb nqa point-to-point, point-to-multipoint thiab multipoint-to-multipoint kev sib txuas lus, thiab muaj peev xwm tsim arbitrary topology tes hauj lwm xws li saw, hnub qub, mesh, thiab hybrid dynamic.
● Kev puas tsuaj-tiv taus thiab kho tus kheej dynamic routing thiab multi-hop relay
Thaum cov nodes txav, nce lossis txo kom nrawm, qhov sib thooj network topology yuav raug hloov kho nyob rau hauv vib nas this, cov kev yuav rov ua dua tshiab, kev hloov kho tshiab ntawm lub sijhawm ntse yuav ua tiav, thiab kev sib txuas ntau lub hop relay yuav raug tswj xyuas ntawm cov nodes.
● Txhawb kev txav ceev ceev, siab-bandwidth, thiab qis-latency adaptive kis tau tus mob uas tiv thaiv ntau txoj kev fading.
● Kev sib tshuam thiab kev sib koom ua ke ntawm kev sib koom ua ke
Tus tsim tag nrho-IP txhawb kev sib kis ntawm ntau hom ntaub ntawv, sib cuam tshuam nrog kev sib txuas lus sib txuas lus, thiab paub txog kev sib tham sib koom ua ke ntawm ntau cov kev pabcuam hauv network.
●Muaj zog tiv thaiv kev cuam tshuam nrog cov kav hlau txais xov ntse, kev xaiv ntse zaus, thiab autonomous zaus hopping
Lub sij hawm sau digital filtering thiab MIMO ntse kav hlau txais xov zoo tiv thaiv kev cuam tshuam tawm ntawm pawg.
Intelligent zaus xaiv kev ua haujlwm hom: Thaum qhov chaw ua haujlwm zaus cuam tshuam nrog, qhov zaus taw tes tsis muaj kev cuam tshuam tuaj yeem raug xaiv ntse rau kev sib txuas hauv network, zoo zam kev cuam tshuam tsis zoo.
Autonomous zaus hopping ua hauj lwm hom: Muab ib tug txheej ntawm kev ua hauj lwm raws nyob rau hauv lub ua hauj lwm zaus band, thiab tag nrho cov network dhia synchronously ntawm kev kub ceev, zoo zam kev cuam tshuam tsis zoo.
Nws txais FEC rau pem hauv ntej kev kho qhov yuam kev thiab ARQ yuam kev tswj kev sib kis cov txheej txheem los txo cov ntaub ntawv xa tawm pob ntawv poob thiab txhim kho cov ntaub ntawv sib kis tau zoo.
● Kev ruaj ntseg encryption
Kev tshawb nrhiav ywj pheej thiab kev txhim kho, kev hloov pauv hloov pauv, algorithms thiab kev sib kis raws tu qauv.Huab cua interface kis tau tus mob siv 64-ntsis yuam sij, uas tuaj yeem ua kom muaj kev sib tw ua ntu zus kom ua tiav channel encryption.
● Muaj kev tsim qauv
Cov cuab yeej siv lub aviation plug-in interface, uas muaj kev vibration tsis kam thiab nruj me ntsis raws li kev tiv thaiv kev vibration kev ua haujlwm ntawm kev thauj mus los.Nws muaj IP66 tiv thaiv qib thiab kev ua haujlwm kub ntau kom ua tau raws li qhov hnyav sab nraum zoov txhua qhov chaw ua haujlwm huab cua.
● Kev ua haujlwm yooj yim thiab kev ua haujlwm yooj yim thiab kev saib xyuas
Muab ntau lub network ports, serial ports thiab Wi-Fi AP, mobile pab kiag li lawm, computers los yog PADs, lub zos los yog tej thaj chaw deb login davhlau ya nyob twg system software, kev khiav hauj lwm kev tswj thiab tu.Nws muaj kev saib xyuas lub sijhawm tiag tiag, GIS daim ntawv qhia thiab lwm yam haujlwm, thiab txhawb nqa cov chaw taws teeb hloov kho software / teeb tsa / kub rov pib dua.
Daim ntawv thov
Wireless ad hoc network xov tooj cua yog siv tau rau hauv non-visual (NLOS) multipath fading ib puag ncig, kev sib txuas lus tseem ceeb ntawm video / ntaub ntawv / suab
●Cov neeg hlau / tsheb tsis muaj neeg tsav tsheb, kev tshawb nrhiav / kev soj ntsuam / tiv thaiv kev ua phem / kev soj ntsuam
