Kuwunika ndi Kuwunika Kwamphamvu kwa Netiweki ya WiFi

Maukonde opanda zingwe apitilizabe kukhala mutu wosangalatsa kwambiri m'magulu amasiku ano olumikizirana, popeza akadali maziko a kafukufuku ndi chitukuko cha matekinoloje omwe akubwera ndikugwiritsa ntchito maukonde. Pamaukadaulo ambiri opanda zingwe ndi mapulogalamu, WiFi ikuwoneka kuti ikugwiritsidwa ntchito kwambiri chifukwa cha kuphweka kwake komanso kusinthasintha. Chifukwa chake, kuchita nawo ophunzira achichepere muzochitika zomwe zimawathandiza kumvetsetsa chiphunzitso chaukadaulo wa WiFi ndikofunikira kwambiri, chifukwa zimawalola kuti azichita bwino. yamikirani ukadaulo wopanda zingwe womwe umayendetsa masewera awo apakanema kunyumba, malo osewerera komanso kusukulu.

Mwamwayi, posachedwapa komanso masiku ano, WiFi yakhala gawo lofunika kwambiri la moyo monga momwe anthu amafunira kuti azitha kulumikizana bwino kwambiri. Izi zimafuna kuti akatswiri akhale ndi chidziwitso cha digito komanso chapamwamba pakupanga maukonde a WiFi omwe amakwaniritsa izi. Zochitika zoterezi zikuphatikizapo kudziwa kuchuluka kwa zipangizo zogwiritsira ntchito WiFi, mwachitsanzo, node ndi ma terminals, zomwe zingathe kuthandizidwa panthawi imodzi kutengera bandwidth yomwe ilipo komanso kuchuluka kwa mawayilesi a WiFi. Izi zimafunika kuti mumvetsetse kusanthula kwa magwiridwe antchito a WiFi ndi kuchuluka kwake, chifukwa kuchedwa kwambiri ndi kutsika sikuloledwanso. Kumvetsetsa mgwirizano pakati pa kufalitsa ndi mphamvu, motero kukhala kofunika kwambiri pakugwirizanitsa zinthu zonse ziwiri.

Maukonde a WiFi amatengera njira yofikira mwachisawawa pomwe siteshoni kapena foni yam'manja imagwira sing'anga yomwe imagawidwa ndi mwayi; njira yotereyi imatsimikizira kuchuluka kwa magwiridwe antchito komanso chilungamo pakati pa ogwiritsa ntchito. Kumbali inayi, kufalikira (ie njira yolumikizirana) ya malo ofikirako/malo oyambira kumatsimikizira kuchuluka kwa ogwiritsa ntchito omwe angapikisane ndi njira ya WiFi nthawi iliyonse yomwe ali ndi data yotumizira. Pakuwunika kowunikira, pomwe cholumikizira cham'manja chili mkati mwa njira yolumikizirana ndi malo olumikizirana, terminal imalumikizidwa kudzera pa ulalo wakuthupi (wopanda zingwe), ndipo ndizotheka kuti cholumikizira choterocho chilumikizidwe ndi malo angapo ofikira nthawi imodzi. koma sizikutanthauza kuti wogwiritsa ntchito amatha kufalitsa nthawi imodzi. Kumbali inayi, pakuwunika mphamvu, ngati malo ofikira amathandizira ma terminals angapo am'manja m'malo ake ofikira, kutulutsa kwadongosolo kwa malo ofikira kumadetsa mwaukadaulo pokhudzana ndi kuchuluka kwa ma terminals olumikizidwa.

Choncho, mphamvu ndi kufalikira ndi mfundo zofunika kwambiri pamanetiweki opanda zingwe kuti ana ndi ophunzira ang'onoang'ono (asanayambe kuyunivesite) ayenera kuwonetseredwa, ndipo kuwonetsedwa kotereku kuyenera kuyambira kuwaphunzitsa momwe network topology imapangidwira komanso momwe kuwerengera / kuchuluka kwa data kumawerengedwera. Pachifukwa ichi, a ntchito yoyang'ana pamanja on kupanga masanjidwe amtundu wamtundu wamalo ofikira a WiFi ndi ma terminals am'manja, kufotokozera mitundu yolumikizirana yolumikizira kuti mumvetsetse kufalikira, komanso kugwiritsa ntchito chiphunzitso cha Shannon kuwonetsa kuchuluka kwa malo ofikira okhala ndi cholumikizira cholumikizidwa chimodzi.. Mfundo zazikuluzikulu zidzafotokozedwa momveka bwino kwa ophunzira kudzera muzochita zomwe zimaphatikizapo kuyerekezera kwachisawawa kwa netiweki topology ndi kuwerengetsera kwapang'onopang'ono kwapakati. Ngakhale kuti ntchitoyi imayang'aniridwa ndi ophunzira azaka zapakati pa 11-13 ndi zaka 14-18, zidzamveka bwino kwa ophunzira aku sekondale ndi omwe akukonzekera ku koleji ndikukhala ndi maziko oyambira pamapulogalamu, ndiye kuti. , amatha kuwerenga ndi kumvetsa mizere yosavuta ya code.

Cholinga cha Ntchitoyi

Pomaliza ntchitoyi, ophunzira adziwa zambiri za momwe angachitire izi:

1) Tsanzirani masanjidwe apamwamba a netiweki a zida zolumikizidwa ndi WiFi (malo ofikira ndi ma terminals am'manja).

2) Chepetsani topology yoyambirira kukhala netiweki yazida zolumikizidwa, kutengera kufalikira kwa WiFi.

3) Kuwerengera kuchuluka kwapakati pa malo aliwonse opezeka pamaneti olumikizidwa.

4) Thamangani ma code a python kuti mugwire ntchito (1) mpaka (3) pamwambapa

Zida/Zinthu Zofunika

Kuti mumalize ntchitoyi,

Ophunzira angafunike kuwerenga pa fomula ya Shannon kuti amvetsetse kuchuluka kwa maukonde a WiFi. Njirayi imaperekedwanso mu kope la python.
Ophunzira ayenera kugwiritsa ntchito Google Colab, yomwe imatha kupezeka kudzera muakaunti yawo ya Gmail. Ulalo wa chikwatu chogawana nawo ndi https://drive.google.com/drive/folders/1U362pWTJ_rRN18yhunrqY1CnNdUC_1Tw?usp=sharing
Kugwirizana kwa Video (ili ndi kabuku ka python)

malangizo

Manambalawa adzaperekedwa pazochitikazo, ndipo ulalo wa Google Colab udzagawidwa kuti ophunzira ayesetse ndikuyesa okha. Masitepe ndi awa:

Lowani ku imelo yanu ndikupeza ulalo wa Google Colab ku foda ya projekiti, yomwe ili ndi mafayilo ndi kabuku ka python kuti muyesere.
Thamangani kayeseleledwe. Kuti apange topology yachisawawa, ophunzira ayenera kuyika kuchuluka kwa malo ofikira, kuchuluka kwa zida zam'manja ndi njira yolumikizirana. Izi zitha kusinthidwa nthawi iliyonse yomwe wophunzira akufuna kuyesa kangapo. Izi zithandiza wophunzirayo kumvetsetsa momwe kulumikizana kungakhudzire magwiridwe antchito a netiweki. Zotsatira zofananira zidzaphatikizanso mphamvu (motengera kuchuluka kwapakati) pagawo lililonse lofikira.
