Inethiwekhi ye-Ad hoc, ezihlelele yonainethiwekhi ye-mesh, isuka ku-Mobile Ad Hoc Networking, noma i-MANET ngamafuphi.
Igama elithi "Ad Hoc" livela kusiLatini futhi lisho ukuthi "Ngenjongo ethile kuphela", okungukuthi, "ngokwenjongo ekhethekile, yesikhashana".Inethiwekhi ye-Ad Hoc iyinethiwekhi yesikhashana yokuzihlela ye-multi-hop ehlanganiswe iqembu lamatheminali eselula aneama-wireless transceivers, ngaphandle kwanoma yisiphi isikhungo sokulawula noma izinsiza zokuxhumana eziyisisekelo.Wonke ama-node kunethiwekhi ye-Ad Hoc anesimo esilinganayo, ngakho-ke asikho isidingo sanoma iyiphi indawo emaphakathi yokulawula nokuphatha inethiwekhi.Ngakho-ke, ukulimala kunoma iyiphi itheminali eyodwa ngeke kuthinte ukuxhumana kwayo yonke inethiwekhi.I-node ngayinye ayinawo umsebenzi wetheminali yeselula kuphela kodwa futhi idlulisela idatha yamanye ama-node.Uma ibanga eliphakathi kwamanodi amabili likhulu kunebanga lokuxhumana okuqondile, indawo emaphakathi idlulisela idatha ukuze bathole ukuxhumana phakathi kwabo.Kwesinye isikhathi ibanga eliphakathi kwamanodi amabili lide kakhulu, futhi idatha idinga ukudluliselwa ngamanodi amaningi ukuze ifinyelele indawo okuyiwa kuyo.
Izinzuzo zobuchwepheshe benethiwekhi ye-ad hoc engenantambo
IWAVEUkuxhumana kwenethiwekhi ye-ad hoc okungenantambo kunezici ezilandelayo nezindlela zakho zokuxhumana eziguquguqukayo namandla okudlulisa anamandla:
●Ukwakhiwa kwenethiwekhi okusheshayo kanye nokuxhumana okuvumelana nezimo
Ngokwesisekelo sokuqinisekisa ukuphakelwa kukagesi, akuvinjelwa ukuthunyelwa kwezinsiza ezisekelayo njengamakamelo amakhompyutha nama-optical fibers.Asikho isidingo sokumba imisele, ukumba izindonga, noma ukusebenzisa amapayipi nezintambo.Ukutshalwa kwezimali zokwakha kuncane, ubunzima buphansi, futhi umjikelezo mfushane.Ingafakwa futhi ifakwe ngokuguquguquka ngezindlela ezihlukahlukene ngaphakathi nangaphandle ukuze kuzuzwe ukwakhiwa kwenethiwekhi okusheshayo ngaphandle kwegumbi lekhompyutha futhi ngezindleko eziphansi.Amanethiwekhi asabalalisiwe angenasikhungo asekela i-point-to-point, i-point-to-multipoint kanye ne-multipoint-to-multipoint, futhi ingakha amanethiwekhi e-topology angenasizathu afana neketango, inkanyezi, i-mesh, ne-hybrid dynamic.
● Umzila oguquguqukayo omelana nokucekela phansi futhi uziphilisa ngokwawo kanye nokudluliselwa kwe-multi-hop
Lapho ama-node enyakaza, anda noma ehla ngokushesha, i-topology yenethiwekhi ehambisanayo izobuyekezwa ngemizuzwana, imizila izokwakhiwa kabusha ngamandla, izibuyekezo ezihlakaniphile zesikhathi sangempela zizokwenziwa, futhi ukudluliswa kwe-multi-hop relay kuzogcinwa phakathi kwama-node.
● Isekela ukunyakaza kwesivinini esiphezulu, umkhawulokudonsa ophezulu, kanye nokudlulisa okuguquguqukayo okubambezele kancane okumelana nokufiphala kwezindlela eziningi.
● Ukuxhumana nokuhlanganiswa kwenethiwekhi
Idizayini ye-IP yonke isekela ukudluliswa okusobala kwezinhlobo ezahlukahlukene zedatha, ixhuma nezinhlelo zokuxhumana ezihlukene, futhi ibona ukuhlanganiswa okusebenzisanayo kwezinsizakalo zamanethiwekhi amaningi.
●Ukumelana nokuphazamiseka okuqinile nge-antenna ehlakaniphile, ukukhethwa kwefrikhwensi ehlakaniphile, ne-autonomous frequency hopping
Ukuhlunga kwedijithali kwesizinda sesikhathi kanye ne-MIMO smart antenna kucindezela ngempumelelo ukuphazamiseka okungaphandle kwebhendi.
Imodi yokusebenza ehlakaniphile yokukhetha ifrikhwensi: Uma iphoyinti lefrikhwensi yokusebenza liphazanyiswa, indawo yefrikhwensi ngaphandle kokuphazamiseka ingakhethwa ngobuhlakani ukuze kudluliselwe inethiwekhi, kugwenywe ngempumelelo ukuphazamiseka okungahleliwe.
Imodi yokusebenza ye-Autonomous frequency hopping: Ihlinzeka nganoma iyiphi isethi yamashaneli asebenzayo ngaphakathi kwebhendi yefrikhwensi yokusebenza, futhi yonke inethiwekhi igxuma ngokuhambisanayo ngesivinini esikhulu, igwema ngempumelelo ukuphazamiseka okunonya.
Yamukela ukulungiswa kwephutha le-FEC phambili kanye nezindlela zokulawula amaphutha ze-ARQ ukuze kuncishiswe izinga lokulahleka kwephakethe lokudluliswa kwedatha nokuthuthukisa ukusebenza kahle kokudluliswa kwedatha.
● Ukubethela kokuphepha
Ucwaningo nokuthuthukiswa okuzimele ngokugcwele, ama-waveform enziwe ngokwezifiso, ama-algorithms kanye nezinqubo zokudlulisela.Ukudluliswa kwesixhumi esibonakalayo somoya kusebenzisa okhiye abangu-64bits, abangakhiqiza ngokuguqukayo ukulandelana kokukrwabha ukuze kuzuzwe ukubethelwa kwesiteshi.
● Idizayini yezimboni
Izinto ezisetshenziswayo zamukela i-plug-in yendiza, enokumelana okuqinile nokudlidliza futhi ihlangabezana ngokuqinile nezidingo zokusebenza zokulwa nokudlidliza zokuthutha ngemoto.Inezinga lokuvikela le-IP66 kanye nebanga lokushisa elibanzi lokuhlangabezana nendawo yokusebenza yangaphandle yesimo sezulu esinzima.
● Ukusebenza okulula nokusebenza okulula nokugcinwa
Nikeza ngezimbobo zenethiwekhi ezihlukahlukene, izimbobo ze-serial kanye ne-Wi-Fi AP, amadivaysi eselula, amakhompyutha noma ama-PAD, isofthiwe yesistimu yetheminali yokungena yasendaweni noma ekude, ukuphathwa nokusebenza nokugcinwa.Inokuqapha kwesikhathi sangempela, imephu ye-GIS neminye imisebenzi, futhi isekela ukuthuthukiswa kwesofthiwe ekude/ukumisa/ukuqalisa kabusha okushisayo.
Isicelo
Irediyo yenethiwekhi yesikhangiso engenantambo isetshenziswa kakhulu ezindaweni ezingabonwayo (NLOS) ezifiphala izindlela eziningi, ukuxhumana okubalulekile kwevidiyo/idatha/izwi.
