Inethiwekhi ye-mesh "inethiwekhi yegridi engenantambo", inethiwekhi "enama-hop amaningi", yathuthukiswa kusuka kunethiwekhi ye-ad hoc, ingenye yobuchwepheshe obubalulekile bokuxazulula inkinga "yemayela lokugcina". Enkambisweni yokuguqukela kunethiwekhi yesizukulwane esilandelayo, i-wireless iwubuchwepheshe obubalulekile. I-wireless mesh ingaxhumana ngokubambisana namanye amanethiwekhi, futhi iyisakhiwo senethiwekhi esiguquguqukayo esingandiswa njalo, futhi noma yimaphi amadivayisi amabili angagcina ukuxhumana okungenantambo.
Isimo esijwayelekile
Ngezici zokuxhumeka kwe-multi-hop kanye ne-topology ye-Mesh, inethiwekhi ye-wireless mesh iguquke yaba yisisombululo esisebenzayo samanethiwekhi ahlukahlukene okufinyelela angenantambo njengenethiwekhi yasekhaya ye-broadband, inethiwekhi yomphakathi, inethiwekhi yebhizinisi kanye nenethiwekhi yendawo yedolobha. Ama-router e-Wireless Mesh akha amanethiwekhi e-AD hoc ngokusebenzisa ukuxhumana kwe-multi-hop, okunikeza ukuthembeka okuphezulu, ukumbozwa kwensizakalo ebanzi kanye nezindleko eziphansi zangaphambilini zenethiwekhi ye-WMN. I-WMN izuza izici eziningi zamanethiwekhi e-AD hoc angenantambo, kodwa kukhona umehluko othile. Ngakolunye uhlangothi, ngokungafani nokuhamba kwama-node enethiwekhi ye-Ad Hoc angenantambo, indawo yama-router e-Mesh angenantambo ivame ukulungiswa. Ngakolunye uhlangothi, uma kuqhathaniswa namanethiwekhi e-Ad Hoc angenantambo ancishisiwe amandla, ama-router e-Mesh angenantambo avame ukuba nokunikezwa kwamandla okuzinzile. Ngaphezu kwalokho, i-WMN nayo ihlukile kumanethiwekhi ezinzwa angenantambo, futhi kuvame ukucatshangwa ukuthi imodeli yebhizinisi phakathi kwama-router e-Mesh angenantambo izinzile, ifana kakhulu nenethiwekhi yokufinyelela evamile noma inethiwekhi yekhampasi. Ngakho-ke, i-WMN ingasebenza njengenethiwekhi yokudlulisela phambili enezinsizakalo ezizinzile, njengenethiwekhi yengqalasizinda yendabuko. Uma isetshenziswa okwesikhashana emisebenzini yesikhashana, i-WMNS ivame ukusebenza njengamanethiwekhi endabuko e-AD hoc eselula.
Ukwakheka okujwayelekile kwe-WMN kuqukethe izakhi ezintathu ezahlukene zenethiwekhi engenantambo: ama-router esango (ama-router anamakhono esango/ibhuloho), ama-router e-Mesh (izindawo zokufinyelela), kanye namakhasimende e-Mesh (eselula noma ngenye indlela). Iklayenti le-Mesh lixhunywe ku-router ye-Mesh engenantambo ngokuxhumeka okungenantambo, futhi i-router ye-Mesh engenantambo yakha inethiwekhi yokudlulisela ezinzile ngendlela yokuxhumana kwe-multi-hop. Ekwakhiweni kwenethiwekhi okujwayelekile kwe-WMN, noma iyiphi i-router ye-Mesh ingasetshenziswa njenge-relay yokudlulisela idatha kwamanye ama-router e-Mesh, kanti amanye ama-router e-Mesh nawo anekhono elengeziwe lama-gateway e-inthanethi. I-router ye-Gateway Mesh idlulisela ithrafikhi phakathi kwe-WMN ne-inthanethi ngesixhumanisi esinezintambo esisheshayo. Ukwakheka kwenethiwekhi okujwayelekile kwe-WMN kungabhekwa njengokwakhiwa kwezindiza ezimbili, lapho indiza yokufinyelela inikeza ukuxhumana kwenethiwekhi kumakhasimende e-Mesh, kanye nezinsizakalo zokudlulisela indiza yokudlulisela phambili phakathi kwama-router e-Mesh. Ngokusetshenziswa okwandayo kobuchwepheshe be-interface engenantambo ebonakalayo ku-WMN, ukwakheka kwenethiwekhi okuklanywe yi-WMN sekuthandwa kakhulu.
I-HUANET inganikeza i-Huawei dual band EG8146X5 WIFI6 Mesh onu.
Uhlelo lokuxhumana lwe-MESH
Kunethiwekhi ye-Mesh, izici ezifana nokuphazamiseka kwesiteshi, ukukhethwa kwenombolo ye-hop kanye nokukhethwa kwemvamisa kufanele kucatshangelwe ngokuphelele. Lesi sigaba sithatha i-WLANMESH ngokusekelwe kuma-802.11s njengesibonelo sokuhlaziya izinhlelo ezahlukene zokuxhumana ezingaba khona. Okulandelayo kuchaza izinhlelo zokuxhumana zemvamisa eyodwa kanye nezinhlelo zokuxhumana zemvamisa ephindwe kabili kanye nokusebenza kwazo.
Ukuxhumana kwe-MESH okuvamise ukuba khona kanye
Uhlelo lokuxhumana lwemvamisa eyodwa lusetshenziswa kakhulu ezindaweni lapho amadivayisi nezinsiza zemvamisa zilinganiselwe khona. Luhlukaniswe nge-single-frequency single-hop kanye ne-single-frequency multi-hop. Kunethiwekhi yemvamisa eyodwa, yonke indawo yokufinyelela engenantambo i-Mesh AP kanye ne-wireless access point Root AP isebenza kubhendi efanayo yemvamisa. Njengoba kuboniswe kuMfanekiso 1, isiteshi esingu-802.11b/g ku-2.4GHz singasetshenziswa ekudluliseni ukufinyelela nokubuyisela. Ngokusho kwendawo yokuphazamiseka kwesiteshi ehlukile ngesikhathi sokusetshenziswa komkhiqizo kanye nenethiwekhi, isiteshi esisetshenziswa phakathi kwama-hops singaba isiteshi esizimele ngokuphelele esingaphazamisi, noma kungaba khona isiteshi esithile sokuphazamiseka (iningi lalawa asendaweni yangempela). Kulokhu, ngenxa yokuphazamiseka phakathi kwama-node angomakhelwane, wonke ama-node awakwazi ukwamukela noma ukuthumela ngesikhathi esifanayo, futhi indlela ye-MAC ye-CSMA/CA kumele isetshenziselwe ukuxoxisana ebangeni le-multi-hop. Ngokwanda kwenani le-hop, i-bandwidth eyabelwe i-Mesh AP ngayinye izoncipha kakhulu, futhi ukusebenza kwenethiwekhi yemvamisa eyodwa kuzoncipha kakhulu.
Ukuxhumana kwe-MESH okuphindwe kabili
Kunethiwekhi yamabhendi amabili, i-node ngayinye isebenzisa amabhendi amabili ahlukene emvamisa ye-backpass kanye nokufinyelela. Isibonelo, isevisi yokufinyelela yendawo isebenzisa isiteshi esingu-2.4GHz 802.1lb/g, kanti inethiwekhi ye-backbone Mesh backpass isebenzisa isiteshi esingu-5.8GHz 802.11a ngaphandle kokuphazamiseka. Ngale ndlela, i-Mesh AP ngayinye ingenza umsebenzi we-backpass kanye ne-forward ngenkathi ikhonza abasebenzisi bokufinyelela bendawo. Uma kuqhathaniswa nenethiwekhi yemvamisa eyodwa, inethiwekhi yemvamisa emibili ixazulula inkinga yokuphazamiseka kwesiteshi yokudluliselwa kwe-back kanye nokufinyelela, futhi ithuthukisa kakhulu ukusebenza kwenethiwekhi. Kodwa-ke, endaweni yangempela kanye nokuxhumana okukhulu, ngoba ibhendi yemvamisa efanayo isetshenziswa phakathi kwezixhumanisi ze-backhaul, akusekho siqinisekiso sokuthi akukho ukuphazamiseka phakathi kweziteshi. Ngakho-ke, ngokwanda kwenani le-hop, i-bandwidth eyabelwe i-Mesh AP ngayinye isathambekele ekwehleni, futhi i-Mesh AP ekude ne-Root AP izoba sengozini ekufinyeleleni kwesiteshi. Ngakho-ke, inani le-hop lokuxhumana kwamabhendi amabili kufanele libekwe ngokuqapha.
