Yintoni inethiwekhi ye-ad hoc engenazingcingo
Inethiwekhi ye-Ad Hoc, eyaziwa ngokuba yi-mobile ad hoc network (i-MANNET), yinethiwekhi yokuzimela yezixhobo eziphathwayo ezinokuthi zinxibelelane ngaphandle kokuxhomekeka kwisiseko esele sikhona okanye ulawulo oluphakathi. Inethiwekhi yenziwa ngokuguquguqukayo njengoko izixhobo zingena kuluhlu lomnye nomnye, zivumela ukuba zitshintshiselane ngedatha yoontanga-kuontanga.
Zeziphi iimpawu zenethiwekhi ye-ad hoc engenazingcingo?
Uthungelwano lwe-ad hoc engenazingcingo, ekwaziwa ngokuba ziinethiwekhi ezizilungiselelayo ngaphandle kwamacingo, zineempawu ezininzi ezahlukileyo ezohlula kuthungelwano lwemveli lonxibelelwano. Ezi mpawu zinokushwankathelwa ngolu hlobo lulandelayo:
Ukunatyiswa kwamagunya kunye nokuzilungiselela
- Uthungelwano lwe-ad hoc olungenazingcingo lunatyiselwe kwindalo, okuthetha ukuba akukho nodi yolawulo esembindini okanye iziseko ezingundoqo ezifunekayo ekusebenzeni kwazo.
- IiNodes kwinethiwekhi zilingana nesimo kwaye ziyakwazi ukunxibelelana ngokuthe ngqo omnye komnye ngaphandle kokuxhomekeka kwisikhululo esisisiseko okanye indawo yokufikelela kwindawo ephakathi.
- Uthungelwano luzilungelelanisa kwaye luzilungiselele, luvumela ukuba luqulunqe kwaye lulungelelanise utshintsho kwimo engqongileyo kunye neendawo ze-node ngokuzenzekelayo.
DI-ynamic Topology
I-topology yenethiwekhi (ulungiselelo lweenodi kunye noqhagamshelo lwazo) kuthungelwano lwe-ad hoc olungenazingcingo luguquguquka kakhulu.
Ii-Nodes zinokuhamba ngokukhululekileyo, ezibangela ukuba unxibelelwano phakathi kwabo lutshintshe rhoqo.
Oku kuguquguquka kufuna ii-algorithms zomzila ezinokuziqhelanisa ngokukhawuleza neenguqu kwi-topology yenethiwekhi kunye nokugcina uqhagamshelwano.
Ii-Multi-Hop Routing
- Kuthungelwano olungenazingcingo lwe-ad hoc, iindawo zokuhlala zisenokungakwazi ukunxibelelana ngokuthe ngqo enye kwenye ngenxa yoluhlu olulinganiselweyo lothumelo.
- Ukoyisa lo mda, iindawo zokuhlala zixhomekeke kumzila we-multi-hop, apho imiyalezo ithunyelwa ukusuka kwindawo enye ukuya kwenye de ifike apho iya khona.
- Oku kuvumela uthungelwano ukuba lugqume indawo enkulu kwaye lugcine uqhagamshelwano naxa iindawo zokuhlala zingekho kuluhlu lonxibelelwano oluthe ngqo.
Uluhlu olulinganiselweyo kunye nezibonelelo
- Iziteshi zonxibelelwano ezingenazingcingo zine-bandwidth elinganiselweyo, enokuthi ithintele inani ledatha enokuthi idluliselwe nangaliphi na ixesha.
- Ukongeza, iindawo zokuhlala kuthungelwano lwe-ad hoc olungenazingcingo zinokuba namandla alinganiselweyo kunye nesakhono sokusetyenzwa, nto leyo ecinezela ngakumbi izibonelelo zenethiwekhi.
- Ukusetyenziswa ngokukuko kwezi zixhobo zinqongopheleyo kubalulekile ekugcineni ukusebenza kwenethiwekhi kunye nokuthembeka.
Ixeshana kunye neNdalo ye-Ad Hoc
Uthungelwano lwe-ad hoc olungenazingcingo luhlala lusetyenziselwa iinjongo ezithile, zexeshana, ezifana noncedo lwentlekele, imisebenzi yasemkhosini, okanye iziganeko zethutyana.
Ziyakwazi ukusetwa ngokukhawuleza kwaye zidilizwe njengoko zifuneka, zibenze balungelelanise kakhulu kwiimeko eziguqukayo.
Imingeni yoKhuseleko
Ukunatyiswa kunye nobume obuguquguqukayo bothungelwano olungenazingcingo lwe-ad hoc luzisa imingeni yokhuseleko olulodwa.
Iindlela zokhuseleko zemveli, ezifana ne-firewall kunye neenkqubo zokubona ukungena, zisenokungasebenzi kolu nxibelelwano.
Iiprothokholi zokhuseleko ezikwinqanaba eliphezulu kunye ne-algorithms ziyafuneka ukukhusela inethiwekhi kuhlaselo kunye nokugcina ubumfihlo bedatha kunye nokuthembeka.
Uthungelwano lwe-ad hoc olungenazingcingo lusenokuquka iindawo ezinesakhono esahlukileyo, esifana neentlobo ezahlukeneyo zothumelo, amandla okusebenza, kunye nobomi bebhetri.
Le heterogeneity ifuna i-algorithms yomzila kunye neeprothokholi ezinokuziqhelanisa neempawu ezahlukeneyo zeenodi kwinethiwekhi.
I-Heterogeneity
Uthungelwano lwe-ad hoc olungenazingcingo lusenokuquka iindawo ezinesakhono esahlukileyo, esifana neentlobo ezahlukeneyo zothumelo, amandla okusebenza, kunye nobomi bebhetri.
Le heterogeneity ifuna i-algorithms yomzila kunye neeprothokholi ezinokuziqhelanisa neempawu ezahlukeneyo zeenodi kwinethiwekhi.
Isishwankathelo, uthungelwano lwe-ad hoc olungenazingcingo luphawulwa ngokunabisa amagunya, ukuzilungelelanisa, itopology eguquguqukayo, umzila we-multi-hop, umda olinganiselweyo kunye nezibonelelo, indalo yethutyana kunye ne-ad hoc, imingeni yokhuseleko, kunye ne-heterogeneity. Ezi mpawu zibenza bafaneleke ngokufanelekileyo kwiintlobo ezininzi zezicelo, kubandakanywa nokusebenza komkhosi, uncedo lweentlekele, kunye neziganeko zexeshana, apho unxibelelwano lwendabuko lunokuthi lungabikho okanye lungasebenzi.
