Shabakadda mesh waa "shabakad shabakadeed oo aan lahayn fiilooyin", waa shabakad "multi-hop", waxaa laga sameeyay shabakad ad hoc ah, waa mid ka mid ah teknoolojiyada muhiimka ah ee lagu xallinayo dhibaatada "maylka ugu dambeeya". Inta lagu jiro geeddi-socodka horumarinta shabakadda jiilka soo socda, wireless-ku waa tignoolajiyad aan laga maarmi karin. Mesh-ka wireless-ka ah wuxuu si iskaashi leh ula xiriiri karaa shabakadaha kale, waana qaab-dhismeedka shabakad firfircoon oo si joogto ah loo ballaarin karo, labada qalabna waxay ilaalin karaan isku-xirka wireless-ka.
Xaaladda guud
Iyada oo la adeegsanayo astaamaha isku xirka multi-hop iyo topology-ga Mesh, shabakadda mesh-ka wireless-ka ayaa isu beddeshay xal wax ku ool ah oo loogu talagalay shabakadaha kala duwan ee marin u helka wireless-ka sida shabakadda guriga ee ballaaran, shabakadda bulshada, shabakadda ganacsiga iyo shabakadda aagga magaalooyinka waaweyn. Routers-ka Wireless Mesh waxay sameeyaan shabakadaha AD hoc iyada oo loo marayo isku xirka multi-hop, kaas oo bixiya isku halayn sare, daboolid adeeg oo ballaaran iyo kharash hoose oo hore loogu talagalay shabakadda WMN. WMN waxay dhaxlaysaa inta badan astaamaha shabakadaha AD hoc ee wireless-ka ah, laakiin waxaa jira kala duwanaansho. Dhinac, si ka duwan dhaqdhaqaaqa shabakadaha Ad Hoc ee wireless-ka ah, goobta router-yada Mesh-ka wireless-ka ah badanaa waa la hagaajiyaa. Dhanka kale, marka la barbar dhigo shabakadaha Ad Hoc ee wireless-ka ah ee tamarta xaddidan, router-yada Mesh-ka wireless-ka ah badanaa waxay leeyihiin sahay koronto oo go'an. Intaa waxaa dheer, WMN sidoo kale way ka duwan tahay shabakadaha dareemayaasha wireless-ka ah, waxaana badanaa la qiyaasaa in qaabka ganacsiga ee u dhexeeya router-yada Mesh-ka wireless-ka uu yahay mid deggan, oo aad ugu eg shabakadda marin u helka caadiga ah ama shabakadda xerada. Sidaa darteed, WMN waxay u dhaqmi kartaa sidii shabakad gudbin ah oo leh adeegyo deggan, sida shabakad kaabayaal dhaqameed. Marka si ku meel gaar ah loogu hawlgeliyo hawlaha muddada-gaaban, WMNS waxay inta badan u dhaqmi kartaa sidii shabakadaha AD hoc ee mobile-ka ah ee dhaqameed.
Qaab-dhismeedka guud ee WMN wuxuu ka kooban yahay saddex qaybood oo shabakadeed oo kala duwan: router-yada albaabka (routers-yada leh awoodaha albaabka/buundada), router-yada Mesh (meelaha marin-u-helka), iyo macaamiisha Mesh (moobaylka ama si kale). Macmiilka Mesh wuxuu ku xiran yahay router-ka Mesh-ka wireless-ka iyada oo loo marayo xiriir wireless ah, router-ka Mesh-ka wireless-kana wuxuu sameeyaa shabakad gudbineed oo deggan oo qaab isku-xir badan. Qaab-dhismeedka shabakadda guud ee WMN, router kasta oo Mesh ah waxaa loo isticmaali karaa sidii gudbin xog ah oo loogu talagalay router-yada kale ee Mesh, router-yada Mesh-ka qaarkoodna waxay sidoo kale leeyihiin awood dheeraad ah oo albaabada Internetka ah. Router-ka albaabka Mesh wuxuu u gudbiyaa taraafikada u dhaxaysa WMN iyo Internetka iyada oo loo marayo xiriir silig oo xawaare sare leh. Qaab-dhismeedka shabakadda guud ee WMN waxaa loo arki karaa inuu ka kooban yahay laba diyaaradood, kaas oo diyaaradda gelitaanka ay siiso isku-xirka shabakadda macaamiisha Mesh, iyo adeegyada gudbinta diyaaradda hore ee u dhaxaysa router-yada Mesh. Iyadoo la kordhinayo isticmaalka tignoolajiyada is-dhexgalka wireless-ka ee dalwaddeed ee WMN, qaab-dhismeedka shabakadda ee ay naqshadeysay WMN ayaa noqday mid aad u caan ah.

Nidaamka isku xirka MESH
Shabakadaha Mesh-ka, arrimaha sida faragelinta kanaalka, xulashada tirada hop-ka iyo xulashada soo noqnoqoshada waa in si buuxda loo tixgeliyaa. Qaybtani waxay qaadanaysaa WLANMESH oo ku salaysan 802.11s tusaale ahaan si loo falanqeeyo nidaamyada shabakadaha ee suurtagalka ah ee kala duwan. Kuwa soo socdaa waxay sharraxayaan nidaamyada shabakadaha hal-soo-noqoshada ah iyo kuwa laba-soo-noqoshada ah iyo waxqabadkooda.
Shabakadda MESH ee hal mar soo noqnoqota
Nidaamka isku xirka hal-mareegta waxaa inta badan loo isticmaalaa meelaha aaladaha iyo ilaha soo noqnoqda ay xaddidan yihiin. Waxaa loo qaybiyaa hal-mareegta hal-mareegta iyo hal-mareegta hal-mareegta. Shabakadaha hal-mareegta ah, dhammaan barta marin-u-helka bilaa-waayirka ah Mesh AP iyo barta marin-u-helka ee fiilada leh Root AP waxay ku shaqeeyaan isla xadka soo noqnoqda. Sida ka muuqata Jaantuska 1, kanaalka 802.11b/g ee 2.4GHz waxaa loo isticmaali karaa gudbinta marin-u-helka iyo soo celinta. Sida ku cad jawiga kala duwan ee faragelinta kanaalka inta lagu jiro hirgelinta badeecada iyo shabakadda, kanaalka loo isticmaalo inta u dhaxaysa hop-yada wuxuu noqon karaa kanaal gebi ahaanba madax-bannaan oo aan faragelin lahayn, ama waxaa jiri kara kanaal faragelin gaar ah (inta badan kan dambe ee deegaanka dhabta ah). Xaaladdan, faragelinta u dhaxaysa qanjidhada deriska ah awgeed, dhammaan qanjidhada ma heli karaan ama ma diri karaan isku mar, habka MAC ee CSMA/CA waa in loo isticmaalaa in lagu gorgortamo heerka hop-ka badan. Iyadoo la kordhinayo tirada hop-ka, baaxadda loo qoondeeyay Mesh AP kasta ayaa si weyn hoos ugu dhici doonta, waxqabadka shabakadda soo noqnoqoshada hal-mareegta dhabta ahna aad ayuu u xaddidan yahay.
Shabakadda MESH ee laba-jibbaaran
Shabakadaha laba-xariiqle, guntin kastaa wuxuu isticmaalaa laba xargo oo kala duwan oo loogu talagalay dib-u-gudbinta iyo gelitaanka. Tusaale ahaan, adeegga marin-u-helka maxalliga ah wuxuu isticmaalaa kanaalka 2.4GHz 802.1lb/g, shabakadda gadaal-u-gudbinta Mesh-ka laf-dhabarta waxay isticmaashaa kanaalka 5.8GHz 802.11a iyada oo aan faragelin lahayn. Sidan, AP kasta oo Mesh ah wuxuu qaban karaa shaqada gadaal-u-gudbinta iyo hore-u-socodka isagoo u adeegaya isticmaalayaasha marin-u-gudbinta maxalliga ah. Marka la barbardhigo shabakadda hal-xariiqle, shabakadda laba-xariiqle ayaa xallisa dhibaatada faragelinta kanaalka ee gudbinta gadaal-u-gudbinta iyo gelitaanka, waxayna si weyn u horumarisaa waxqabadka shabakadda. Si kastaba ha ahaatee, deegaanka dhabta ah iyo shabakadda baaxadda weyn, sababtoo ah isku-xidhka soo noqnoqda ayaa loo isticmaalaa inta u dhaxaysa isku-xirka dib-u-gudbinta, weli ma jirto wax dammaanad ah oo ah inaysan jirin faragelin u dhaxaysa kanaallada. Sidaa darteed, iyadoo la kordhinayo tirada soo-gudbinta, baaxadda loo qoondeeyay Mesh AP kasta ayaa weli u janjeerta inay hoos u dhacdo, Mesh AP-na meel fog oo ka fog Root AP-ga ayaa dhibaato ku noqon doonta marin-u-gudbinta kanaalka. Sidaa darteed, tirada soo-gudbinta ee shabakadda laba-xariiqle waa in si taxaddar leh loo dejiyaa.
