Kodi opanda zingwe ad hoc network ndi chiyani
Netiweki ya Ad Hoc, yomwe imadziwikanso kuti mobile ad hoc network (MANET), ndi njira yodzipangira yokha pazida zam'manja zomwe zimatha kulumikizana popanda kudalira zida zomwe zidalipo kale kapena utsogoleri wapakati. Netiweki imapangidwa mwamphamvu pomwe zida zimabwera mosiyanasiyana, kuwalola kuti azisinthana ndi anzawo.
Kodi maukonde opanda zingwe ad hoc ndi ati?
Maukonde opanda zingwe ad hoc, omwe amadziwikanso kuti ma network odzipangira okha opanda zingwe, ali ndi mawonekedwe angapo omwe amawasiyanitsa ndi maukonde achikhalidwe. Makhalidwewa akhoza kufotokozedwa mwachidule motere:
Decentralized and Self Organising
- Maukonde opanda zingwe ad hoc amagawidwa m'chilengedwe, kutanthauza kuti palibe njira yapakati yowongolera kapena zomangamanga zomwe zimafunikira kuti zigwire ntchito.
- Ma Node mu netiweki ndi ofanana mu mawonekedwe ndipo amatha kulumikizana mwachindunji popanda kudalira malo oyambira kapena malo ofikira pakati.
- Maukonde amadzipangira okha komanso amadzipangira okha, kulola kuti apange ndikusintha kusintha kwa chilengedwe ndi malo a node okha.
Dynamic Topology
Netiweki topology (makonzedwe a node ndi kulumikizana kwawo) mu netiweki yopanda zingwe ndi yamphamvu kwambiri.
Node zimatha kuyenda momasuka, zomwe zimapangitsa kuti kulumikizana pakati pawo kusinthe pafupipafupi.
Kusinthasintha uku kumafuna ma aligorivimu owongolera omwe amatha kusintha mwachangu kusintha kwa netiweki topology ndikusunga kulumikizana.
Multi-Hop Routing
- Mu netiweki yopanda zingwe, ma node sangathe kulumikizana mwachindunji wina ndi mnzake chifukwa cha kuchuluka kwa kufalikira.
- Kuti athane ndi vutoli, ma node amadalira ma multi-hop routing, pomwe mauthenga amatumizidwa kuchokera ku mfundo imodzi kupita ku ina mpaka atafika komwe akupita.
- Izi zimathandiza kuti ma netiweki azitha kulumikiza malo okulirapo ndikusunga kulumikizana ngakhale ma node sali m'njira yolumikizana mwachindunji.
Bandwidth ndi Zida Zochepa
- Njira zoyankhulirana zopanda zingwe zili ndi bandwidth yochepa, yomwe imatha kuletsa kuchuluka kwa deta yomwe imatha kutumizidwa nthawi iliyonse.
- Kuphatikiza apo, ma node omwe ali mu netiweki yopanda zingwe amatha kukhala ndi mphamvu zochepa ndikuwongolera, zomwe zimalepheretsanso ma netiweki.
- Kugwiritsa ntchito moyenera zinthu zochepazi ndikofunikira kuti maukonde agwire bwino ntchito komanso odalirika.
Zakanthawi komanso Zachilengedwe
Maukonde opanda zingwe ad hoc nthawi zambiri amagwiritsidwa ntchito pazinthu zinazake, zosakhalitsa, monga chithandizo chatsoka, zochitika zankhondo, kapena zochitika zosakhalitsa.
Amatha kukhazikitsidwa mwachangu ndikugwetsedwa ngati pakufunika, kuwapangitsa kukhala osinthika kwambiri pakusintha.
Zovuta Zachitetezo
Kusasinthika kwa ma network opanda zingwe kumabweretsa zovuta zapadera zachitetezo.
Njira zodzitetezera zachikhalidwe, monga zotchingira zozimitsa moto ndi njira zodziwira zolowera, sizingakhale zogwira ntchito pamanetiweki awa.
Ma protocol apamwamba achitetezo ndi ma aligorivimu amafunikira kuteteza netiweki kuti isawukidwe ndikusunga zinsinsi za data ndi kukhulupirika.
Maukonde opanda zingwe ad hoc atha kukhala ndi ma node okhala ndi kuthekera kosiyanasiyana, monga kusiyanasiyana kotumizirana, mphamvu yosinthira, ndi moyo wa batri.
Kusiyanasiyana kumeneku kumafuna ma aligorivimu ndi ma protocol omwe angagwirizane ndi mawonekedwe osiyanasiyana a node pamaneti.
Heterogeneity
Maukonde opanda zingwe ad hoc atha kukhala ndi ma node okhala ndi kuthekera kosiyanasiyana, monga kusiyanasiyana kotumizirana, mphamvu yosinthira, ndi moyo wa batri.
Kusiyanasiyana kumeneku kumafuna ma aligorivimu ndi ma protocol omwe angagwirizane ndi mawonekedwe osiyanasiyana a node pamaneti.
Mwachidule, maukonde opanda zingwe ad hoc amadziwika ndi kugawikana kwawo, kudzipanga okha, topology yamphamvu, maulendo amtundu wa multi-hop, bandwidth yochepa ndi zothandizira, zachilengedwe zosakhalitsa komanso zosayembekezereka, zovuta zachitetezo, komanso kusiyanasiyana. Makhalidwewa amawapangitsa kukhala oyenerera ntchito zosiyanasiyana, kuphatikizapo ntchito zankhondo, chithandizo chatsoka, ndi zochitika zosakhalitsa, kumene maukonde ochezera achikhalidwe angakhale osapezeka kapena osatheka.
