Waht waa MESH network

Shabakadda mesh waa "shabakad xajmi la'aan ah", waa shabakad "multi-hop", oo laga soo saaray shabakad ad hoc, waa mid ka mid ah tignoolajiyada muhiimka ah ee lagu xalliyo dhibaatada "mayl u dambeeya".Inta lagu jiro geedi socodka horumarinta shabakada jiilka soo socda, wireless-ku waa tignoolajiyada lama huraanka ah.Mesh-ka bilaa-waayirka ah waxa uu si wada jir ah ula xidhiidhi karaa shabakadaha kale, waana qaab-dhismeed shabakadeed firfircoon oo si joogto ah loo ballaadhin karo, laba qalab kastana waxa ay ilaalin karaan isku xidhka wireless-ka.

Xaalada guud

Astaamaha isku xirka multi-hop iyo Mesh topology, shabakadda mesh wireless waxay u rogmatay xal wax ku ool ah oo loogu talagalay shabakadaha marinka wireless-ka ee kala duwan sida shabakadda guriga ee ballaaran, shabakadda bulshada, shabakadda ganacsiga iyo shabakadda aagga caasimadda.Mashruucyada Wireless-ka ee Wireless-ka ah waxay sameeyaan shabakado AD hoc iyada oo loo marayo isku xirka multi-hop, kaas oo bixiya isku halleyn sare, caynsanaan adeeg iyo qiimo hoose oo hooseeya ee isku xirka WMN.WMN waxay dhaxashaa inta badan sifooyinka shabakadaha AD hoc wireless, laakiin waxaa jira kala duwanaansho.Dhinaca kale, si ka duwan dhaq-dhaqaaqa qanjidhada shabakada wireless Ad Hoc, meesha ay ku yaalliin mesh router-ka wireless-ka ayaa inta badan go'an.Dhanka kale, marka la barbar dhigo shabakadaha Ad Hoc-ka ee wireless-ka ee tamarta xaddidan, dariiqyada Mesh-ka wireless-ka ayaa inta badan leh sahay koronto oo go'an.Intaa waxaa dheer, WMN sidoo kale way ka duwan tahay shabakadaha dareemayaasha wireless-ka, waxaana badanaa loo maleynayaa in qaabka ganacsi ee u dhexeeya jiheeyayaasha Mesh wireless uu yahay mid deggan, oo la mid ah shabakada caadiga ah ee gelitaanka ama shabakada dhismaha.Sidaa darteed, WMN waxay u dhaqmi kartaa sidii shabakad gudbin oo leh adeegyo deggan, sida shabakad kaabayaal dhaqameed.Marka si ku meel gaadh ah loo geeyo hawlaha wakhtiga gaaban, WMNS waxay inta badan u dhaqmi kartaa sidii shabakado AD hoc mobaylo ah oo dhaqameed.

Nashqada guud ee WMN waxa ay ka kooban tahay saddex walxood oo shabakad wireless ah oo kala duwan: router gateway (router-ka leh awooda albaabka/buundada), mesh router (goobaha gelitaanka), iyo macaamiisha Mesh (mobile ama si kale).Macmiilka Mesh waxa uu ku xidhan yahay mesh-ka bilaa-waayirka ah ee mesh-ka iyada oo loo marayo xidhiidhka bilaa-waayirka ah, iyo mesh router-ka bilaa-waayirka ah waxa uu samaysaa shabakad gudbinta oo xasiloon oo ah qaab isku xidhka multi-hop.Qaab dhismeedka guud ee shabakada WMN, Mesh router kasta waxa loo isticmaali karaa gudbinta xogta ee router-yada kale ee Mesh, iyo qaar ka mid ah dariiqyada Mesh sidoo kale waxay leeyihiin awood dheeri ah oo ah albaabada internetka.Gateway Mesh router waxa uu u gudbiyaa taraafikada u dhaxaysa WMN iyo intarneedka iyada oo la adeegsanayo isku xirka fiilooyinka xawaaraha sare leh.Nashqada isku xidhka guud ee WMN waxa loo tixgalin karaa in uu ka kooban yahay laba diyaaradood, kuwaas oo diyaarada gelaysa ay bixiso isku xidhka shabakada macaamiisha Mesh, iyo gudbinta diyaarada u gudbisa adeegyada isu-gudbinta ee u dhexeeya mesh router.Iyada oo ay sii kordhayso isticmaalka tignoolajiyada is-dhex-galka wireless-ka ah ee WMN, qaab-dhismeedka shabakadda ee ay nashqadaysay WMN waxa uu noqday mid aad iyo aad caan u ah.

Nidaamka isku xidhka MESH

Isku xirka Mesh, arrimaha sida faragelinta kanaalka, xulashada tirada hop iyo xulashada inta jeer waa in si buuxda loo tixgeliyo.Qaybtani waxay qaadanaysaa WLANMESH oo ku salaysan 802.11s tusaale ahaan si loo falanqeeyo qorshayaasha isku xidhka ee kala duwan ee suurtogalka ah.Kuwan soo socdaa waxa ay sharxayaan isku xidhid hal mar ah iyo qorshayaasha isku xidhka laba jeer ee soo noqnoqda iyo waxqabadkooda.

Isku xirka MESH ee soo noqnoqda hal mar

Nidaamka isku xirka hal-mareegta waxaa inta badan loo adeegsadaa meelaha aaladaha iyo agabka soo noqnoqda ay xaddidan yihiin.Waxa loo qaybiyaa hal-frequency hal-hop iyo hal-frequency multi-hop.Isku xirka hal-soo noqnoqoshada, dhammaan barta gelitaanka bilaa-waayirka Mesh AP iyo barta gelitaanka fiilada ee Root AP waxay ku shaqeeyaan guutooyin isku mid ah.Sida ku cad Jaantuska 1, kanaalka 802.11b/g ee 2.4GHz waxa loo isticmaali karaa gelitaanka iyo soo celinta gudbinta.Marka loo eego jawiga faragelinta kanaalka ee kala duwan inta lagu jiro hirgelinta badeecada iyo shabakadda, kanaalka loo isticmaalo inta u dhaxaysa hops wuxuu noqon karaa kanaal aan faragelin lahayn oo gebi ahaanba madax-bannaan, ama waxaa jiri kara kanaal faragalin gaar ah (inta badan kan dambe ee deegaanka dhabta ah). ).Xaaladdan oo kale, sababtoo ah faragelinta u dhaxaysa qanjidhada deriska ah, dhammaan qanjidhada ma heli karaan ama soo diri karaan isku mar, iyo habka MAC ee CSMA/CA waa in loo isticmaalo gorgortanka kala duwanaanshaha multi-hop.Kordhinta tirinta hop-ka, xadhkaha loo qoondeeyay Mesh AP kasta ayaa si aad ah u yaraan doona, iyo waxqabadka shabakada hal jeer ee dhabta ah ayaa si weyn u xaddidi doona.

Isku xirka MESH ee laba-soo noqnoqda

Isku-xidhka labada-band, noodh kastaa wuxuu isticmaalaa laba xabbo oo soo noqnoqda oo kala duwan si uu u socdo iyo gelitaanka.Tusaale ahaan, adeegga gelitaanka maxalliga ahi wuxuu adeegsadaa kanaalka 2.4GHz 802.1lb/g, iyo shabakadda mesh dhabarka dhabarka ee laf dhabarta waxay isticmaashaa kanaalka 5.8GHz 802.11a faragelin la'aan.Sidan, Mesh AP kasta wuxuu qaban karaa shaqada dhabarka iyo hore u socodka inta uu u adeegayo isticmaalayaasha gelitaanka maxalliga ah.Marka la barbardhigo shabakada hal mar ee soo noqnoqda, shabakada laba-geesoodka ah waxay xallisaa dhibaatada faragelinta kanaalka ee gudbinta iyo helitaanka dhabarka, waxayna si weyn u wanaajisaa waxqabadka shabakada.Si kastaba ha ahaatee, jawiga dhabta ah iyo isku xirka ballaaran, sababtoo ah isku midka ah ee isku midka ah ayaa loo isticmaalaa inta u dhaxaysa isku xirka dhabarka, weli ma jirto dammaanad ah in aysan jirin faragalin u dhexeeya kanaalka.Sidaa darteed, korodhka tirinta hop-ka, baaxadda loo qoondeeyay Mesh AP kasta ayaa weli u janjeerta inay hoos u dhacdo, iyo Mesh AP oo ka fog Root AP waxay noqon doontaa khasaare helitaanka kanaalka.Sidaa darteed, tirada hop-ka ee isku xidhka labada-band waa in si taxadar leh loo dejiyaa.
