Waht yog MESH network

Mesh network yog "wireless grid network", yog "multi-hop", yog tsim los ntawm ad hoc network, yog ib qho ntawm cov thev naus laus zis tseem ceeb los daws qhov teeb meem " mais kawg".Nyob rau hauv tus txheej txheem ntawm evolution mus rau tiam tom ntej network, wireless yog ib tug indispensable technology.Wireless mesh tuaj yeem sib txuas lus sib koom tes nrog lwm cov tes hauj lwm, thiab yog ib qho kev sib txuas lus zoo sib xws uas tuaj yeem txuas ntxiv txuas ntxiv, thiab ob qho khoom siv tuaj yeem tswj xyuas kev sib txuas wireless.

General xwm txheej

Nrog rau cov yam ntxwv ntawm kev sib txuas ntawm ntau qhov kev sib txuas thiab Mesh topology, wireless mesh network tau hloov zuj zus mus rau hauv cov kev daws teeb meem zoo rau ntau yam kev siv wireless xws li broadband hauv tsev network, zej zog network, kev lag luam network thiab cheeb tsam cheeb tsam network.Wireless Mesh routers tsim AD hoc tes hauj lwm los ntawm ntau qhov kev sib txuas sib txuas, uas muab kev ntseeg siab dua, kev pab cuam dav dua thiab qis dua tus nqi rau WMN networking.WMN tau txais feem ntau ntawm cov yam ntxwv ntawm wireless AD hoc networks, tab sis muaj qee qhov sib txawv.Ntawm ib sab, tsis zoo li kev txav mus los ntawm wireless Ad Hoc network nodes, qhov chaw ntawm wireless Mesh routers feem ntau yog kho.Ntawm qhov tod tes, piv rau lub zog-tswj wireless Ad Hoc tes hauj lwm, wireless Mesh routers feem ntau muaj lub zog ruaj khov.Tsis tas li ntawd, WMN kuj tseem txawv ntawm wireless sensor tes hauj lwm, thiab nws feem ntau xav tias cov qauv kev lag luam ntawm wireless Mesh routers yog qhov ruaj khov, zoo ib yam li kev nkag mus rau hauv network lossis tsev kawm ntawv network.Yog li ntawd, WMN tuaj yeem ua raws li kev xa xov txuas nrog cov kev pabcuam ruaj khov, xws li kev sib koom ua ke ib txwm muaj.Thaum xa mus rau ib ntus rau cov haujlwm luv luv, WMNS tuaj yeem ua raws li ib txwm siv mobile AD hoc networks.

Cov qauv dav dav ntawm WMN muaj peb qhov sib txawv ntawm cov wireless network: rooj vag routers (routers nrog lub rooj vag / choj muaj peev xwm), Mesh routers (cov ntsiab lus nkag), thiab Mesh cov neeg siv khoom (mobile lossis lwm yam).Tus neeg siv Mesh txuas nrog lub wireless Mesh router los ntawm kev sib txuas wireless, thiab lub wireless Mesh router tsim ib qho kev sib txuas lus ruaj khov nyob rau hauv daim ntawv ntawm ntau qhov kev sib txuas.Hauv kev sib txuas lus dav dav ntawm WMN, ib qho Mesh router tuaj yeem siv los ua cov ntaub ntawv xa mus rau lwm cov Mesh routers, thiab qee qhov Mesh routers kuj muaj peev xwm ntxiv ntawm Internet gateways.Lub rooj vag Mesh router xa mus rau kev khiav tsheb ntawm WMN thiab Is Taws Nem dhau ntawm kev sib txuas ceev ceev.Kev sib txuas lus dav dav ntawm WMN tuaj yeem suav tias yog muaj ob lub dav hlau, uas lub dav hlau nkag mus muab kev sib txuas hauv network rau Mesh cov neeg siv khoom, thiab lub dav hlau xa mus rau xa cov kev pab cuam ntawm Mesh routers.Nrog rau kev siv virtual wireless interface technology hauv WMN, lub network architecture tsim los ntawm WMN tau dhau los ua neeg nyiam.

MESH networking scheme

Hauv Mesh networking, yam xws li kev cuam tshuam channel, xaiv tus lej plhaw thiab xaiv zaus yuav tsum raug txiav txim siab.Tshooj lus no yuav siv WLANMESH raws li 802.11s ua piv txwv los txheeb xyuas ntau yam kev sib txuas ua ke.Cov hauv qab no piav qhia txog kev sib koom ua ke ib leeg thiab kev sib txuas lus dual-frequency thiab lawv cov kev ua tau zoo.

Ib zaus MESH networking

Lub tswv yim sib txuas ib zaug yog siv nyob rau hauv cov cheeb tsam uas cov cuab yeej siv thiab cov peev txheej tsawg tsawg.Nws tau muab faib ua ib zaug ib zaug ib zaug thiab ib zaug ib zaug multi-hop.Hauv kev sib txuas lus ib zaug, txhua qhov chaw nkag wireless Mesh AP thiab wired access point Root AP ua haujlwm hauv tib zaus.Raws li pom hauv daim duab 1, channel 802.11b / g ntawm 2.4GHz tuaj yeem siv rau kev nkag mus thiab xa rov qab.Raws li qhov sib txawv channel cuam tshuam ib puag ncig thaum siv cov khoom lag luam thiab lub network, cov channel siv nruab nrab ntawm cov hops yuav yog ib qho kev ywj pheej tsis muaj kev cuam tshuam, lossis tej zaum yuav muaj qee qhov cuam tshuam channel (feem ntau tom kawg hauv ib puag ncig tiag tiag. ).Hauv qhov no, vim muaj kev cuam tshuam ntawm cov neeg nyob sib ze, tag nrho cov nodes tsis tuaj yeem tau txais lossis xa tib lub sijhawm, thiab MAC mechanism ntawm CSMA / CA yuav tsum tau siv los sib tham hauv ntau qhov hops.Nrog rau qhov nce ntawm cov hop suav, qhov bandwidth faib rau txhua Mesh AP yuav txo qis, thiab qhov kev ua tau zoo ntawm lub network ib zaus yuav raug txwv heev.

Dual-frequency MESH networking

Hauv kev sib tham dual-band, txhua lub node siv ob qhov sib txawv zaus rau kev rov qab thiab nkag mus.Piv txwv li, cov kev pabcuam hauv zos siv 2.4GHz 802.1lb/g channel, thiab lub nraub qaum Mesh backpass network siv 5.8GHz 802.11a channel yam tsis muaj kev cuam tshuam.Ua li no, txhua Mesh AP tuaj yeem ua qhov backpass thiab xa mus ua haujlwm thaum ua haujlwm rau cov neeg siv hauv zos.Piv nrog rau tib zaus network, dual zaus network daws cov teeb meem cuam tshuam ntawm kev xa rov qab thiab kev nkag mus, thiab txhim kho kev ua haujlwm zoo hauv network.Txawm li cas los xij, nyob rau hauv qhov tseeb ib puag ncig thiab kev sib txuas loj loj, vim tias tib zaus siv cov kab sib txuas ntawm cov backhaul txuas, tseem tsis tau lees tias tsis muaj kev cuam tshuam ntawm cov channel.Yog li ntawd, nrog rau qhov nce ntawm cov hop suav, qhov bandwidth faib rau txhua Mesh AP tseem pheej poob qis, thiab Mesh AP nyob deb ntawm lub hauv paus AP yuav muaj qhov tsis zoo hauv kev nkag mus rau channel.Yog li ntawd, lub hop suav ntawm dual-band networking yuav tsum tau teem nrog ceev faj.
