Waa maxay shabakada ad hoc wireless
Shabakadda Ad Hoc, oo sidoo kale loo yaqaano mobaylka ad hoc network (MANET), waa shabakad isku xidha aaladaha moobaylka oo la xidhiidhi kara iyada oo aan ku tiirsanayn kaabayaal hore u jiray ama maamul dhexe. Shabakadda waxaa loo sameeyay si firfircoon marka aaladaha ay soo galaan kala duwanaanshaha midba midka kale, taas oo u oggolaanaysa inay isweydaarsadaan xogta isku-fac-fadeed.
Waa maxay sifooyinka shabakada ad hoc wireless?
Shabakadaha ad hoc-ka ee bilaa-wireless-ka ah, oo sidoo kale loo yaqaan shabkada is-abaabula ee bilaa-waayirka ah, waxay leeyihiin dhowr astaamood oo kala duwan oo ay kaga duwan yihiin shabakadaha isgaarsiinta ee soo jireenka ah. Sifooyinkan waxaa lagu soo koobi karaa sida soo socota:
Baahsan oo Is-abaabulay
- Shabakadaha ad hoc-ka ee bilaa-waayirka ah waa kuwo baahsan dabeecad ahaan, taasoo la macno ah inaysan jirin wax kontorool dhexe ah ama kaabayaasha looga baahan yahay hawlgalkooda.
- Nodes-ka shabakadu waa siman yihiin xaalad ahaan waxayna si toos ah ula xidhiidhi karaan midba midka kale iyada oo aan ku tiirsanayn saldhigga saldhiga ama barta gelitaanka dhexe.
- Shabakadu waa is-abaabulka iyo is-habaynta, taas oo u oggolaanaysa in ay sameyso oo ay la qabsato isbeddellada deegaanka iyo meelaha noodhka ah si toos ah.
Dynamik Topology
Shabakadda topology-ga (habaynta qanjidhada iyo isku xidhkooda) ee shabakada ad hoc-ka waa mid firfircoon.
Nodes waxay u dhaqaaqi karaan si xor ah, taasoo keenaysa in isku xidhka iyaga ka dhexeeya uu si joogto ah isu beddelo.
Dhaqdhaqaaqaani wuxuu u baahan yahay algorithms-ka-wareejinta kuwaas oo si dhakhso ah ula qabsan kara isbeddelada topology-ga shabakada oo ilaalin kara isku xirnaanta.
Jidka Multi-Hop
- Shabakadda ad hoc-ka ee bilaa-waayirka ah, noodhadhku waxa laga yaabaa inaanay si toos ah ula xidhiidhin midba midka kale sababtoo ah baaxadda gudbinta oo xadidan.
- Si looga gudbo xaddidan, noodhadhku waxay ku tiirsan yihiin marin-hawleed badan, halkaas oo farriimaha laga soo gudbiyo hal nood oo loo gudbiyo mid kale ilaa ay ka gaadhaan meesha ay u jeedaan.
- Tani waxay u oggolaaneysaa shabakadu inay daboosho aag weyn oo ay ilaaliso isku xirnaanta xitaa marka qanjidhada aysan ku jirin xadka isgaarsiinta tooska ah.
Xadka Xadidan iyo Khayraadka
- Kanaalka isgaadhsiinta bilaa-waayirka ah ayaa leh xajmi xaddidan, kaas oo xaddidi kara cadadka xogta la gudbin karo wakhti kasta.
- Intaa waxaa dheer, noodhadhka shabakada ad hoc-ka ee bilaa-waayirka ah waxa laga yaabaa inay leeyihiin awood xadidan iyo awoodaha habaynta, taas oo sii adkeynaysa ilaha shabakada.
- Isticmaalka hufan ee ilahan xaddidan ayaa muhiim u ah ilaalinta waxqabadka shabakada iyo isku halaynta.
Ku meel gaadhka iyo Dabeecadda Ad Hoc
Shabakado xayaysiis la'aan ah ayaa inta badan loo hawlgeliyaa ujeedooyin gaar ah, ku meel gaar ah, sida gargaarka musiibada, hawlgallada milatariga, ama dhacdooyinka ku meel gaarka ah.
Si degdeg ah ayaa loo dejin karaa oo loo dumin karaa marka loo baahdo, taasoo ka dhigaysa inay si aad ah ula qabsanayaan xaaladaha isbeddelka.
Caqabadaha Amniga
Dabeecadda fir-fircoon ee shabakadaha ad hoc-ka ee wireless-ku waxay soo bandhigaysaa caqabado amni oo gaar ah.
Hababka amniga dhaqameed, sida dab-damiska iyo hababka ogaanshaha soo gelitaanka, ayaa laga yaabaa inaanay waxtar u lahayn shabakadahan.
Hab-maamuusyada amniga horumarsan iyo algorithms ayaa looga baahan yahay si ay shabakadda uga ilaaliyaan weerarrada oo ay u ilaaliyaan xogta gaarka ah iyo daacadnimada.
Shabakadaha ad hoc-ka ee bilaa-wireless-ka ah waxa ay ka koobnaan karaan nood leh awoodo kala duwan, sida kala duwanaanta kala-gudbinta, awoodda habaynta, iyo nolosha batteriga.
Kala duwanaanshiyahani wuxuu u baahan yahay algorithms iyo borotokool la jaanqaadi kara sifooyinka kala duwan ee qanjidhada shabakada.
Heterogeneity
Shabakadaha ad hoc-ka ee bilaa-wireless-ka ah waxa ay ka koobnaan karaan nood leh awoodo kala duwan, sida kala duwanaanta kala-gudbinta, awoodda habaynta, iyo nolosha batteriga.
Kala duwanaanshiyahani wuxuu u baahan yahay algorithms iyo borotokool la jaanqaadi kara sifooyinka kala duwan ee qanjidhada shabakada.
Marka la soo koobo, shabakadaha ad hoc-ka ee bilaa-waayirka ah waxaa lagu gartaa maamul-daadejintooda, is-abaabulkooda, topology firfircoon, marin-hawleed badan, xajmiyeed iyo agab xaddidan, dabeecad ku-meel-gaar ah iyo ku-meel-gaar ah, caqabadaha amniga, iyo kala duwanaanshaha. Tilmaamahan ayaa ka dhigaya kuwo si fiican ugu habboon codsiyo kala duwan, oo ay ku jiraan hawlgallada milatariga, gargaarka musiibada, iyo dhacdooyinka ku-meel-gaadhka ah, halkaasoo shabakadaha isgaarsiineed ee dhaqameed aan la heli karin ama aan macquul ahayn.
