Iyini inethiwekhi ye-ad hoc engenantambo
Inethiwekhi ye-Ad Hoc, eyaziwa nangokuthi inethiwekhi yesikhangiso seselula (i-MANET), iyinethiwekhi ezilungiselela yona yamadivayisi eselula akwazi ukuxhumana ngaphandle kokuthembela kungqalasizinda ekhona ngaphambili noma ekuphathweni okumaphakathi. Inethiwekhi yakheka ngokushintshashintshayo njengoba amadivayisi eza ebangeni elinye nelinye, eliwavumela ukuthi ashintshisane ngedatha kontanga kuya-kontanga.
Yiziphi izici zenethiwekhi ye-ad hoc engenantambo?
Amanethiwekhi esikhangiso angenantambo, abuye aziwe ngokuthi amanethiwekhi azihlelayo angenawaya, anezici ezimbalwa ezihlukile eziwehlukanisa kunethiwekhi yokuxhumana evamile. Lezi zici zingafingqwa ngale ndlela elandelayo:
I-Decentralized and Self-Zihlela
- Amanethiwekhi esikhangiso angenantambo ahlukaniswa ngokwemvelo, okusho ukuthi ayikho indawo yokulawula emaphakathi noma ingqalasizinda edingekayo ukuze asebenze.
- Ama-Node kunethiwekhi ayalingana ngesimo futhi angaxhumana ngokuqondile ngaphandle kokuthembela esiteshini esiyisisekelo noma indawo yokufinyelela emaphakathi.
- Inethiwekhi iyazihlela futhi iyazilungiselela, iyivumela ukuthi yakheke futhi ivumelane nezinguquko zemvelo kanye nezindawo zamanodi ngokuzenzakalelayo.
DI-ynamic Topology
I-topology yenethiwekhi (ukuhlelwa kwamanodi nokuxhumana kwawo) kunethiwekhi ye-ad hoc engenantambo inamandla kakhulu.
Ama-Node angahamba ngokukhululeka, okwenza ukuxhumana phakathi kwawo kushintshe njalo.
Lokhu kuguquguquka kudinga ama-algorithms omzila akwazi ukuzivumelanisa ngokushesha nezinguquko ku-topology yenethiwekhi futhi agcine ukuxhumana.
I-Multi-Hop Routing
- Kunethiwekhi yezikhangiso ezingenantambo, ama-node angase angakwazi ukuxhumana ngokuqondile ngenxa yobubanzi obulinganiselwe bokudlulisela.
- Ukuze unqobe lo mkhawulo, ama-node ancike emzileni we-multi-hop, lapho imilayezo idluliselwa khona isuka endaweni eyodwa iye kwenye ize ifike lapho iya khona.
- Lokhu kuvumela inethiwekhi ukuthi ihlanganise indawo enkulu futhi igcine ukuxhumeka ngisho nalapho amanodi engekho phakathi kwebanga lokuxhumana eliqondile.
Umkhawulokudonsa Onomkhawulo kanye Nezinsiza
- Iziteshi zokuxhumana okungenantambo zinomkhawulokudonsa olinganiselwe, ongakhawulela inani ledatha engadluliswa nganoma yisiphi isikhathi.
- Ukwengeza, ama-node kunethiwekhi yesikhangiso engenantambo angase abe namandla alinganiselwe kanye namandla okucubungula, okuqhubeka nokubeka engcupheni izinsiza zenethiwekhi.
- Ukusetshenziswa ngempumelelo kwalezi zinsiza ezinomkhawulo kubalulekile ekugcineni ukusebenza kwenethiwekhi nokuthembeka.
Imvelo yesikhashana kanye ne-Ad Hoc
Amanethiwekhi esikhangiso angenantambo avame ukusetshenziselwa izinjongo ezithile, zesikhashana, ezifana nokusiza ezinhlekeleleni, ukusebenza kwezempi, noma imicimbi yesikhashana.
Zingasethwa ngokushesha futhi zidilizwe njengoba kudingeka, zizenze zivumelane nezimo ezishintshayo.
Izinselele zokuphepha
Ukuhlukaniswa nokuguquka kwesimo samanethiwekhi esikhangiso angenawaya kuletha izinselele zokuphepha eziyingqayizivele.
Izindlela zokuphepha zendabuko, ezifana nezindonga zokuvikela kanye namasistimu okuthola ukungena, zingase zingasebenzi kulawa manethiwekhi.
Izivumelwano zokuphepha ezithuthukisiwe kanye nama-algorithms ayadingeka ukuze kuvikelwe inethiwekhi ekuhlaselweni futhi kugcinwe ubumfihlo bedatha nobuqotho.
Amanethiwekhi esikhangiso angenantambo angase aqukathe ama-node anamakhono ahlukene, afana nobubanzi obuhlukahlukene bokudlulisela, amandla okucubungula, nempilo yebhethri.
Lokhu kuhlukahluka kudinga ama-algorithms omzila kanye namaphrothokholi angakwazi ukuzivumelanisa nezici ezihlukahlukene zamanodi kunethiwekhi.
I-Heterogeneity
Amanethiwekhi esikhangiso angenantambo angase aqukathe ama-node anamakhono ahlukene, afana nobubanzi obuhlukahlukene bokudlulisela, amandla okucubungula, nempilo yebhethri.
Lokhu kuhlukahluka kudinga ama-algorithms omzila kanye namaphrothokholi angakwazi ukuzivumelanisa nezici ezihlukahlukene zamanodi kunethiwekhi.
Kafushane, amanethiwekhi esikhangiso angenantambo abonakala ngokuhlukaniswa kwawo, ukuzihlela, i-topology eguquguqukayo, umzila we-multi-hop, umkhawulokudonsa olinganiselwe kanye nezinsiza, imvelo yesikhashana neyesikhashana, izinselele zokuphepha, kanye nokuhlukahluka. Lezi zici zizenza zifanelekele kahle uhla olubanzi lwezinhlelo zokusebenza, okuhlanganisa ukusebenza kwezempi, ukusiza izinhlekelele, nemicimbi yesikhashana, lapho amanethiwekhi okuxhumana okuvamile engase angatholakali noma angasebenzi.
