Waht numuyoboro wa MESH

Umuyoboro wa Mesh ni "umuyoboro udafite insinga", ni umuyoboro wa "multi-hop", watejwe imbere numuyoboro udasanzwe, ni bumwe mu buhanga bwingenzi bwo gukemura ikibazo cya "kilometero yanyuma".Muburyo bwubwihindurize kumurongo uzaza, umuyoboro ni tekinoroji yingirakamaro.Wireless mesh irashobora kuvugana ubufatanye nizindi miyoboro, kandi ni urusobe rwimikorere rwubaka rushobora kwagurwa ubudahwema, kandi ibikoresho bibiri byose birashobora gukomeza guhuza imiyoboro.

Muri rusange

Hamwe nibiranga imiyoboro myinshi ya hop hamwe na topologiya ya Mesh, umuyoboro wa mesh utagira umurongo wahindutse igisubizo cyiza kumiyoboro inyuranye itagendanwa nkumuyoboro mugari, umuyoboro mugari, umuyoboro wibigo hamwe numuyoboro wa metropolitan.Routers ya Wireless Mesh ikora imiyoboro ya AD hoc binyuze mumikoranire myinshi-hop, itanga ubwizerwe buhanitse, serivisi yagutse hamwe nigiciro cyo hejuru kumurongo wa WMN.WMN iragwa byinshi mubiranga imiyoboro idasanzwe ya AD hoc, ariko hariho itandukaniro.Ku ruhande rumwe, bitandukanye no kugendana imiyoboro ya Ad Hoc idafite umurongo, aho imiyoboro ya Mesh itagira umugozi isanzwe ikosorwa.Ku rundi ruhande, ugereranije n’ingufu zidafite ingufu zidasanzwe za Ad Hoc, imiyoboro ya Mesh itagira amashanyarazi isanzwe ifite amashanyarazi ahamye.Mubyongeyeho, WMN nayo itandukanye numuyoboro wa sensor sensor, kandi mubisanzwe hafatwa ko imishinga yubucuruzi hagati ya Mesh router idafite simusiga ihagaze neza, bisa nkibisanzwe byinjira cyangwa urusobe rwikigo.Kubwibyo, WMN irashobora gukora nkumuyoboro wohereza hamwe na serivisi zihamye, nkurusobe rwibikorwa remezo gakondo.Iyo yoherejwe by'agateganyo kubikorwa byigihe gito, WMNS irashobora gukora nkimiyoboro gakondo ya AD igendanwa.

Ubwubatsi rusange bwa WMN bugizwe nibintu bitatu bitandukanye byumuyoboro utagira umugozi: inzira ya enterineti (inzira zifite ubushobozi bwamarembo / ikiraro), inzira ya Mesh (aho igera), hamwe nabakiriya ba Mesh (mobile cyangwa ubundi).Umukiriya wa Mesh yahujwe na router ya Mesh idafite umugozi binyuze mumashanyarazi adafite umugozi, kandi router ya Mesh itagira umurongo ugereranya umuyoboro uhagaze neza muburyo bwo guhuza byinshi.Muburyo rusange bwububiko bwa WMN, inzira ya Mesh iyariyo yose irashobora gukoreshwa nkamakuru yohereza amakuru kubandi ba Mesh bayobora, kandi bamwe mubayobora Mesh nabo bafite ubushobozi bwinyongera bwamarembo ya enterineti.Irembo rya Mesh router yohereza traffic hagati ya WMN na interineti hejuru yumuvuduko wihuse.Imiyoboro rusange yububiko bwa WMN irashobora gufatwa nkigizwe nindege ebyiri, aho indege yinjira itanga imiyoboro ihuza abakiriya ba Mesh, hamwe nindege yohereza imbere itanga serivise hagati ya Mesh router.Hamwe no gukoresha ikoreshwa rya tekinoroji ya interineti itagaragara muri WMN, imiyoboro y'urusobekerane yateguwe na WMN yarushijeho gukundwa.

Gahunda ya MESH

Mumuyoboro wa Mesh, ibintu nkumuyoboro woguhuza, guhitamo numero ya hop no guhitamo inshuro bigomba gusuzumwa byuzuye.Iki gice gifata WLANMESH ishingiye kuri 802.11s nkurugero rwo gusesengura gahunda zitandukanye zishoboka.Ibikurikira bisobanura guhuza umurongo umwe hamwe na gahunda ebyiri zo guhuza imiyoboro n'imikorere yabyo.

Umuyoboro umwe wa MESH

Gahunda imwe yo guhuza imiyoboro ikoreshwa cyane cyane mubice aho ibikoresho nibikoresho bigarukira.Igabanijwemo inshuro imwe imwe-imwe hamwe na-inshuro nyinshi-hop.Mumuyoboro umwe, imiyoboro yose itagikoreshwa Mesh AP hamwe nu nsinga zinjira Imizi AP ikora mumurongo umwe.Nkuko bigaragara ku gishushanyo 1, umuyoboro 802.11b / g kuri 2.4GHz urashobora gukoreshwa muburyo bwo kugaruka no kugaruka.Ukurikije uburyo butandukanye bwo guhuza imiyoboro itandukanye mugihe cyo gushyira mubikorwa ibicuruzwa numuyoboro, umuyoboro ukoreshwa hagati ya hops ushobora kuba umuyoboro wigenga rwose utabangamiye, cyangwa hashobora kubaho umuyoboro runaka wivanga (ibyinshi mubyanyuma mubidukikije nyirizina) ).Muri iki kibazo, kubera kwivanga hagati yumuturanyi, imitwe yose ntishobora kwakira cyangwa kohereza icyarimwe, kandi uburyo bwa MAC bwa CSMA / CA bugomba gukoreshwa mubiganiro murwego rwa hop-hop.Hamwe no kwiyongera kwa hop, umurongo wagabanijwe kuri buri Mesh AP uzagabanuka cyane, kandi imikorere yumurongo umwe rukumbi uzaba muto cyane.

Imiyoboro ibiri ya MESH

Mumurongo wibice bibiri, buri node ikoresha imirongo ibiri itandukanye kugirango isubire inyuma kandi igere.Kurugero, serivise yohagera ikoresha 2.4GHz 802.1lb / g umuyoboro, naho umuyoboro winyuma Mesh winyuma ukoresha 5.8GHz 802.11a umuyoboro utabangamiye.Muri ubu buryo, buri Mesh AP irashobora gukora inyuma yinyuma no gukora imbere mugihe ikorera abakoresha binjira.Ugereranije numuyoboro umwe wumurongo umwe, imiyoboro ibiri yumurongo ikemura ikibazo cyumuyoboro woguhuza kwinyuma no kugerwaho, kandi bitezimbere cyane imikorere yumurongo.Nyamara, mubidukikije nyirizina hamwe n’urusobe runini, kubera ko umurongo umwe wa interineti ukoreshwa hagati yinyuma yinyuma, ntacyakwemeza ko nta kwivanga hagati yimiyoboro.Kubwibyo, hamwe no kwiyongera kwa hop, umurongo wagenewe buri Mesh AP uracyakomeza kugabanuka, kandi Mesh AP iri kure yumuzi AP izaba ifite ikibazo cyo kubona imiyoboro.Kubwibyo, ibyiringiro byo guhuza ibice bibiri bigomba gushyirwaho ubwitonzi.
