Inethiwekhi ye-Ad hoc, i-self-organizedumnatha womnatha, isuka kwiMobile Ad Hoc Networking, okanye MANET ngokufutshane.Igama elithi "Ad Hoc" lisuka kwisiLatini kwaye lithetha "Ngenjongo ethile kuphela", oko kukuthi, "ngenjongo ekhethekileyo, okwethutyana".Inethiwekhi ye-Ad Hoc yinethiwekhi ye-multi-hop yethutyana yokuzilungiselela eyenziwe liqelaiitheminali ezihambayongee-transceivers ezingenazingcingo, ngaphandle kweziko lolawulo okanye izibonelelo zonxibelelwano ezisisiseko.Zonke iinodi kwinethiwekhi ye-Ad Hoc zinesimo esilinganayo, ngoko akukho mfuneko yokuba nayiphi na i-node ephakathi yokulawula nokulawula inethiwekhi.Ngoko ke, umonakalo kuyo nayiphi na i-terminal ayiyi kuchaphazela unxibelelwano lwenethiwekhi yonke.I-node nganye ayinayo kuphela umsebenzi we-terminal yeselula kodwa iphinde idlulisele phambili idatha kwezinye iindawo.Xa umgama phakathi kweenodi ezimbini umkhulu kunomgama wonxibelelwano oluthe ngqo, i-node ephakathi idlulisela idatha ukuze bafezekise unxibelelwano olufanayo.Ngamanye amaxesha umgama phakathi kweenodi ezimbini ude kakhulu, kwaye idatha kufuneka idluliselwe kwiinodi ezininzi ukufikelela kwindawo ekuyiwa kuyo.
Izinto ezilungileyo zeteknoloji ye-ad hoc yenethiwekhi engenazingcingo
● Ukwakhiwa kothungelwano olukhawulezayo kunye nothungelwano oluguquguqukayo
Kwisiseko sokuqinisekisa unikezelo lwamandla, aluthintelwanga ngokusasazwa kwezibonelelo ezixhasayo ezifana namagumbi eekhomputha kunye neefiber optical.Akukho mfuneko yokwemba imisele, ukugrumba iindonga, okanye ukuqhuba imibhobho neengcingo.Utyalo-mali lokwakha luncinci, ubunzima buphantsi, kwaye umjikelo ufutshane.Iyakwazi ukuthunyelwa kwaye ifakwe ngokuguquguqukayo kwiindlela ezahlukeneyo ngaphakathi nangaphandle ukufezekisa ukwakhiwa kwenethiwekhi ngokukhawuleza ngaphandle kwegumbi lekhompyutha kunye neendleko eziphantsi.Uthungelwano olusasazwayo olungenaziko luxhasa i-point-to-point, i-point-to-multipoint kunye ne-multipoint-to-multipoint yonxibelelwano, kwaye inokwakha uthungelwano lwe-topology olungekho mthethweni olufana nekhonkco, inkwenkwezi, i-mesh, kunye ne-hybrid dynamic.
● Ukumelana nokutshatyalaliswa kunye nokuziphilisa kwendlela eguqukayo kunye ne-multi-hop relay
Xa i-nodes ihamba, inyuka okanye iyancipha ngokukhawuleza, i-topology yenethiwekhi ehambelanayo iya kuhlaziywa ngemizuzwana, iindlela ziya kuphinda zakhiwe ngamandla, ukuhlaziywa kwexesha langempela kuya kwenziwa, kwaye ukuhanjiswa kwe-multi-hop relay kuya kugcinwa phakathi kwee-nodes.
● Intshukumo yesantya esiphezulu, i-high-bandwidth, kunye ne-low-latency adaptive transmission echasene nobuninzi beendlela.
● Uqhagamshelwano kunye nokudibanisa inethiwekhi
Uyilo lwe-IP yonke luxhasa ukuhanjiswa okucacileyo kweentlobo ezahlukeneyo zedatha, ukudibanisa kunye neenkqubo zonxibelelwano ezingafaniyo, kunye nokuqonda ukudibanisa okusebenzisanayo kweenkonzo zenethiwekhi ezininzi.
●Ukuchasana nokuphazamiseka okunamandla kunye ne-antenna ehlakaniphile, ukhetho lwamafrikhwensi alumkileyo, kunye ne-autonomous frequency hopping
Ixesha lokucoca idijithali kunye ne-eriyali ye-MIMO ehlakaniphile icinezela ngokufanelekileyo ukuphazamiseka ngaphandle kwebhendi.
Imowudi yokusebenza yokhetho olukrelekrele: Xa indawo yokusebenza iphazamiseka, indawo yokuphindaphinda ngaphandle kokuphazamiseka inokukhethwa ngobukrelekrele kuthumelo lwenethiwekhi, ngokufanelekileyo ukuthintela uphazamiseko olungenamkhethe.
Imowudi yokusebenza ye-Autonomous frequency hopping: Ibonelela ngayo nayiphi na isethi yamatshaneli asebenzayo ngaphakathi kwebhendi yamaza okusebenza, kwaye yonke inethwekhi itsiba ngokuhambelanayo ngesantya esiphezulu, ithintela ngokufanelekileyo uphazamiseko olulunya.
Yamkela i-FEC phambili yokulungiswa kwempazamo kunye ne-ARQ yolawulo lwempazamo yokulawula iindlela zokunciphisa izinga lokulahleka kwepakethi yokuhanjiswa kwedatha kunye nokuphucula ukusebenza kakuhle kokuhanjiswa kwedatha.
● Uguqulelo oluntsonkothileyo
Uphando oluzimeleyo ngokupheleleyo kunye nophuhliso, iifomati zamaza ezilungelelanisiweyo, i-algorithms kunye neeprothokholi zothumelo.Ukuhanjiswa kwe-air interface kusebenzisa izitshixo ze-64bits, ezinokuthi zivelise ngokuguquguqukayo ulandelelwano lokukrazula ukufikelela kwi-encryption yetshaneli.
● Uyilo lwemizi-mveliso
Isixhobo samkela iplagi ye-aviation plug-in interface, enokumelana nokungcangcazela okuqinileyo kwaye ihlangabezana ngokungqongqo neemfuno zokusebenza ezichasene nokungcangcazela kothutho lweemoto.Inomgangatho wokhuseleko we-IP66 kunye noluhlu olubanzi lobushushu obusebenzayo ukuhlangabezana nemekobume enzima yangaphandle yokusebenza kwemozulu.
● Ukusebenza ngokulula kunye nokusebenza ngokulula kunye nokugcinwa
Ukubonelela ngezibuko ezahlukeneyo zothungelwano, izibuko ze-serial kunye ne-Wi-Fi AP, izixhobo eziphathwayo, iikhompyutha okanye ii-PADs, i-software yenkqubo ye-terminal yokungena yasekhaya okanye ekude, ulawulo lokusebenza kunye nokugcinwa.Inokubeka iliso ngexesha langempela, imephu ye-GIS kunye neminye imisebenzi, kwaye ixhasa ukuphuculwa kwesoftware ekude / uqwalaselo / ukuqalisa kwakhona okushushu.
