Ma Micro-drone amathaNetiweki ya MESH ndikugwiritsanso ntchito ma network a ad-hoc m'munda wa ma drones. Mosiyana ndi ma network wamba a AD hoc network, ma netiweki amtundu wa drone mesh samakhudzidwa ndi mtunda panthawi yoyenda, ndipo liwiro lawo nthawi zambiri limakhala lothamanga kwambiri kuposa ma network omwe amadzipangira okha.
Mapangidwe ake amtaneti amagawidwa kwambiri. Ubwino wake ndikuti kusankha njira kumatsirizidwa ndi ma node ochepa pamaneti. Izi sizimangochepetsa kusinthana kwa zidziwitso zapaintaneti pakati pa ma node komanso kugonjetsera kuipa kowongolera njira zapakati.
Mapangidwe a netiweki a gulu la UAVMtengo MESHakhoza kugawidwa mu dongosolo planar ndi masango dongosolo.
Mu dongosolo la planar, maukonde amakhala olimba kwambiri komanso otetezeka, koma ofooka scalability, omwe ali oyenerera ma network ang'onoang'ono odzipangira okha.
M'magulu ophatikizika, maukondewa ali ndi mphamvu zokulirapo ndipo ndi oyenera kwambiri pa intaneti yayikulu ya drone swarm ad-hoc.
Planar Structure
Dongosolo la pulani limatchedwanso peer-to-peer structure. M'mapangidwe awa, node iliyonse ndi yofanana pakugawa mphamvu, kapangidwe ka maukonde, ndi kusankha njira.
Chifukwa cha chiwerengero chochepa cha ma drone node ndi kugawa kosavuta, maukonde ali ndi mphamvu zolimba komanso chitetezo chapamwamba, ndipo kusokoneza pakati pa njira ndizochepa.
Komabe, pamene chiwerengero cha node chikuwonjezeka, tebulo loyendetsera ntchito ndi chidziwitso cha ntchito chomwe chimasungidwa mu node iliyonse chikuwonjezeka, kuchuluka kwa maukonde kumawonjezeka, ndipo kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake kakuwonjezeka kwambiri, zomwe zimapangitsa kuti dongosololi likhale lovuta kulamulira ndi kugwa.
Choncho, dongosolo la planar silingakhale ndi ma node ambiri panthawi imodzimodzi, zomwe zimapangitsa kuti zikhale zovuta komanso zimakhala zoyenera kwa ma network ang'onoang'ono a MESH.
Kapangidwe ka Clustering
Kapangidwe kaphatikizidwe ndikugawa ma drone node kukhala ma network angapo osiyanasiyana malinga ndi ntchito zawo zosiyanasiyana. Mu sub-network iliyonse, node yofunikira imasankhidwa, yomwe ntchito yake ndikukhala ngati malo olamulira a sub-network ndikugwirizanitsa ma node ena pa intaneti.
Ma node ofunikira a sub-network iliyonse mumagulu ophatikizana amalumikizidwa ndikulumikizana wina ndi mnzake. Kusinthana kwachidziwitso pakati pa ma node osakhala makiyi kumatha kuchitidwa kudzera m'malo ofunikira kapena mwachindunji.
Ma node ofunikira ndi mafungulo osafunikira a sub-network yonse pamodzi amapanga ma network clustering. Malinga ndi masanjidwe osiyanasiyana a node, imatha kugawidwanso mumagulu amtundu umodzi komanso kuphatikiza ma frequency angapo.
(1)Kuphatikizika kwa pafupipafupi
M'magulu amtundu umodzi wamagulu, pali mitundu inayi ya ma node pa intaneti, yomwe ndi mutu wa cluster / non-cluster head nodes, zipata / magawo ogawa. Ulalo wa msana umapangidwa ndi mitu yamagulu ndi ma node a zipata. Node iliyonse imalumikizana pafupipafupi.
Kapangidwe kameneka kamakhala kosavuta komanso kofulumira kupanga netiweki, ndipo kuchuluka kwa ma frequency band ndikokweranso. Komabe, kamangidwe kameneka kameneka kamakhala kovutirapo, monga kuphatikizika pakati pa ma tchanelo pomwe kuchuluka kwa ma node pamaneti kumawonjezeka.
Pofuna kupewa kulephereka kwa ntchito zomwe zimachitika chifukwa cha kusokonezedwa kwa ma frequency amtundu, dongosololi liyenera kupewedwa pomwe utali wa gulu lililonse uli wofanana ndi netiweki yayikulu yodzipangira ma drone.
(2)Multi-frequency Clustering
Zosiyana ndi magulu amtundu umodzi, omwe ali ndi gulu limodzi pamtundu uliwonse, magulu ambiri amtundu uliwonse ali ndi zigawo zingapo, ndipo gawo lililonse limakhala ndi magulu angapo. Mu netiweki yolumikizana, ma node a netiweki amatha kugawidwa m'magulu angapo. Ma node osiyanasiyana pagulu amagawidwa m'magulu am'magulu amagulu ndi ma membala amagulu malinga ndi milingo yawo, ndipo ma frequency osiyanasiyana amaperekedwa.
M'magulu, magulu amagulu amagulu ali ndi ntchito zosavuta ndipo sizidzawonjezera kwambiri maulendo apamtunda, koma mitu yamagulu iyenera kuyang'anira gululo, ndikukhala ndi chidziwitso chovuta kwambiri chowongolera, chomwe chimawononga mphamvu zambiri.
Mofananamo, luso loyankhulirana limasiyananso malinga ndi magawo osiyanasiyana a node. Kukwera kwa mulingo, kumapangitsanso kuthekera kokulirapo. Kumbali inayi, node ikakhala yamagulu awiri panthawi imodzi, zikutanthauza kuti mfundoyi iyenera kugwiritsa ntchito maulendo osiyanasiyana kuti igwire ntchito zambiri, kotero kuti chiwerengero cha ma frequency ndi ofanana ndi chiwerengero cha ntchito.
Mu dongosolo ili, mutu wa masango amalankhulana ndi mamembala ena mumagulu ndi ma nodes mumagulu ena a magulu, ndipo mauthenga a gulu lirilonse samasokonezana. Kapangidwe kameneka ndi koyenera kudzipangira maukonde pakati pa ma drones akuluakulu. Poyerekeza ndi gulu limodzi lamagulu, limakhala ndi scalability bwino, katundu wapamwamba, ndipo amatha kuthana ndi deta yovuta kwambiri.
Komabe, chifukwa node ya mutu wamagulu imayenera kugwiritsira ntchito deta yambiri, mphamvu yogwiritsira ntchito mphamvu imakhala yothamanga kwambiri kuposa magulu ena amagulu, choncho moyo wapaintaneti ndi wamfupi kusiyana ndi mawonekedwe amtundu umodzi wamagulu. Kuonjezera apo, kusankha kwa magulu a mutu wamagulu pamtundu uliwonse wamagulu osakanikirana sikunakhazikitsidwe, ndipo node iliyonse imatha kugwira ntchito ngati mutu wamagulu. Kwa node inayake, kaya ingakhale mutu wa tsango zimatengera mawonekedwe a netiweki kuti asankhe kuyambitsa makina ophatikiza. Chifukwa chake, ma network clustering algorithm amatenga gawo lofunikira pakuphatikiza maukonde.
