Inethiwekhi ye-Mesh "inethiwekhi yegridi engenantambo", iyinethiwekhi "ye-multi-hop", ithuthukiswe kusuka kunethiwekhi ye-ad hoc, ingenye yobuchwepheshe obuyinhloko bokuxazulula inkinga "yemayela lokugcina".Enqubweni yokuguqukela kunethiwekhi yesizukulwane esilandelayo, i-wireless ubuchwepheshe obubalulekile.I-wireless mesh ingaxhumana ngokubambisana namanye amanethiwekhi, futhi iyisakhiwo senethiwekhi esiguqukayo esinganwetshwa ngokuqhubekayo, futhi noma imaphi amadivaysi amabili angagcina ukuxhumana okungenantambo.
Isimo esijwayelekile
Ngezimpawu ze-multi-hop interconnection kanye ne-Mesh topology, inethiwekhi ye-wireless mesh isiguquke yaba yisixazululo esisebenzayo samanethiwekhi okufinyelela angenantambo ahlukahlukene njengenethiwekhi yasekhaya ye-broadband, inethiwekhi yomphakathi, inethiwekhi yebhizinisi kanye nenethiwekhi yendawo yedolobha elikhulu.Amarutha e-Wireless Mesh akha amanethiwekhi e-AD hoc ngoxhumano lwe-multi-hop, olunikeza ukuthembeka okuphezulu, ukumbozwa kwesevisi okubanzi kanye nezindleko ezingaphambili eziphansi zenethiwekhi ye-WMN.I-WMN izuza njengefa izici eziningi zamanethiwekhi e-AD hoc angenawaya, kodwa kunomehluko othile.Ngakolunye uhlangothi, ngokungafani nokuhamba kwamanodi enethiwekhi ye-Ad Hoc engenawaya, indawo yamarutha e-wireless Mesh ngokuvamile iyalungiswa.Ngakolunye uhlangothi, uma kuqhathaniswa namanethiwekhi e-Ad Hoc angenantambo acindezelwe amandla, amarutha e-wireless Mesh ngokuvamile anokunikezwa kwamandla okungaguquki.Ngaphezu kwalokho, i-WMN nayo ihlukile kumanethiwekhi ezinzwa ezingenantambo, futhi ngokuvamile kucatshangwa ukuthi imodeli yebhizinisi phakathi kwamarutha e-wireless Mesh izinzile, ifana kakhulu nenethiwekhi yokufinyelela evamile noma inethiwekhi yekhempasi.Ngakho-ke, i-WMN ingasebenza njengenethiwekhi yokudlulisela enamasevisi azinzile, njengenethiwekhi yengqalasizinda evamile.Uma isetshenziselwa imisebenzi yesikhashana esifushane, i-WMNS ngokuvamile ingasebenza njengamanethiwekhi eselula e-AD hoc.
Isakhiwo esijwayelekile se-WMN siqukethe izinto ezintathu ezihlukene zenethiwekhi engenantambo: amarutha amasango (amarutha anekhono lesango/ibhuloho), amarutha e-Mesh (izindawo zokufinyelela), kanye namaklayenti e-Mesh (iselula noma ngenye indlela).Iklayenti le-Mesh lixhunywe kumzila we-wireless Mesh ngoxhumo olungenantambo, futhi irutha ye-Mesh engenantambo yakha inethiwekhi yokudlulisela ezinzile ngendlela yokuxhumanisa ama-multi-hop.Esakhiweni senethiwekhi evamile ye-WMN, noma iyiphi irutha ye-Mesh ingasetshenziswa njengesidluliseli sokudlulisa idatha samanye amarutha e-Mesh, futhi amanye amarutha e-Mesh nawo anekhono elengeziwe lamasango e-inthanethi.Irutha yesango le-Mesh idlulisela ithrafikhi phakathi kwe-WMN ne-inthanethi ngesixhumanisi esinentambo esinesivinini esikhulu.Isakhiwo senethiwekhi evamile ye-WMN singathathwa njengehlanganisa izindiza ezimbili, lapho indiza yokufinyelela ihlinzeka ngoxhumano lwenethiwekhi kumakhasimende e-Mesh, kanye nezinsizakalo zokudlulisela phambili indiza eya phambili phakathi kwamarutha e-Mesh.Ngokusetshenziswa okwandayo kobuchwepheshe besixhumi esibonakalayo obungenantambo ku-WMN, i-architecture yenethiwekhi edizayinwe yi-WMN isidume kakhulu.

Uhlelo lwenethiwekhi lwe-MESH
Kunethiwekhi ye-Mesh, izici ezifana nokuphazamiseka kwesiteshi, ukukhetha izinombolo ze-hop nokukhetha imvamisa kufanele kucatshangelwe ngokugcwele.Lesi sigaba sithatha i-WLANMESH esekelwe ku-802.11s njengesibonelo sokuhlaziya izikimu zokuxhumana ezingaba khona ezihlukahlukene.Okulandelayo kuchaza izinhlelo zenethiwekhi ze-single-frequency networking kanye nokusebenza kwazo.
Inethiwekhi ye-MESH yefrikhwensi eyodwa
Uhlelo lwenethiwekhi ye-single-frequency networking lusetshenziswa kakhulu ezindaweni lapho amadivaysi nezinsiza zokuvama kunqunyelwe khona.Ihlukaniswe nge-single-frequency single-hop kanye ne-single-frequency multi-hop.Kunethiwekhi yefrikhwensi eyodwa, yonke indawo yokufinyelela engenantambo i-Mesh AP kanye nephoyinti lokufinyelela elinentambo I-Root AP isebenza ngebhendi yefrikhwensi efanayo.Njengoba kuboniswe kuMfanekiso 1, isiteshi 802.11b/g ku-2.4GHz singasetshenziselwa ukufinyelela nokubuyisela ukudlulisa.Ngokwesimo esihlukene sokuphazamiseka kwamashaneli phakathi nokuqaliswa komkhiqizo nenethiwekhi, ishaneli elisetshenziswa phakathi kwama-hop lingase libe ishaneli elingaphazamisi elizimele ngokuphelele, noma kungase kube neshaneli ethile yokuphazamisa (iningi lakamuva endaweni yangempela. ).Kulesi simo, ngenxa yokuphazamiseka phakathi kwama-node angomakhelwane, wonke ama-node awakwazi ukwamukela noma ukuthumela ngesikhathi esifanayo, futhi indlela ye-MAC ye-CSMA/CA kufanele isetshenziselwe ukuxoxisana ebangeni le-multi-hop.Ngokukhula kwesibalo se-hop, umkhawulokudonsa owabelwe i-Mesh AP ngayinye uzokwehla kakhulu, futhi ukusebenza kwangempela kwenethiwekhi yefrikhwensi eyodwa kuzokhawulelwa kakhulu.
Inethiwekhi ye-MESH ye-Dual-frequency
Kunethiwekhi ye-dual-band, inodi ngayinye isebenzisa amabhendi amabili ahlukene wefrikhwensi yokubuyela emuva nokufinyelela.Isibonelo, isevisi yendawo yokufinyelela isebenzisa isiteshi esingu-2.4GHz 802.1lb/g, futhi inethiwekhi yomgogodla we-Mesh backpass isebenzisa isiteshi esingu-5.8GHz 802.11a ngaphandle kokuphazamiseka.Ngale ndlela, i-Mesh AP ngayinye ingenza i-backpass kanye nomsebenzi wangaphambili ngenkathi isebenzela abasebenzisi bokufinyelela bendawo.Uma kuqhathaniswa nenethiwekhi yefrikhwensi eyodwa, inethiwekhi yefrikhwensi ekabili ixazulula inkinga yokuphazamiseka kwesiteshi yokudlulisela emuva nokufinyelela, futhi ithuthukisa kakhulu ukusebenza kwenethiwekhi.Kodwa-ke, endaweni yangempela kanye nenethiwekhi enkulu, ngenxa yokuthi ibhande lemvamisa elifanayo lisetshenziswa phakathi kwezixhumanisi ze-backhaul, akukabikho isiqinisekiso sokuthi akukho ukuphazamiseka phakathi kweziteshi.Ngakho-ke, ngokwanda kokubala kwe-hop, umkhawulokudonsa owabelwe i-Mesh AP ngayinye usathanda ukwehla, futhi i-Mesh AP ekude ne-Root AP izoba sengozini ekufinyeleleni isiteshi.Ngakho-ke, isibalo se-hop sokunethiwekha kwe-dual-band kufanele sisethwe ngokuqapha.
