Micro-drone inoputikaMESH network ndiyo imwezve yekushandisa ye mobile ad-hoc network mumunda we drones. Yakasiyana neyakajairwa mobile AD hoc network, network nodes mune drone mesh network haabatwe nenzvimbo panguva yekufamba, uye kumhanya kwavo kunowanzo kukurumidza kupfuura kuya kwechinyakare nhare yekuzvironga network.
Mamiriro ayo emambure anonyanya kugoverwa. Chakanakira ndechekuti kusarudzwa kwenzira kunopedzwa nenhamba shoma yemanodhi mune network. Izvi hazvingodzikisi shanduko yeruzivo rwenetiweki pakati pemanodhi asi zvakare inokunda iyo yakashata yeanopfuura-centralized routing control.
Iyo network chimiro cheUAV swarmMESH networkinogona kukamurwa kuita planar chimiro uye clustered structure.
Muchirongwa chechirongwa, network ine kusimba kwakanyanya uye chengetedzo, asi isina kusimba scalability, iyo yakakodzera kune madiki-anozvironga network.
Muchimiro chakabatanidzwa, network ine scalability yakasimba uye inonyanya kukodzera kune yakakura-scale drone swarm ad-hoc networking.
Planar Structure
Chimiro chechirongwa chinonziwo peer-to-peer structure. Muchimiro ichi, node imwe neimwe yakafanana maererano nekugovera kwesimba, network chimiro, uye sarudzo yenzira.
Nekuda kwehuwandu hushoma hwema drone node uye kugovera kuri nyore, network ine kusimba kwakasimba uye kuchengetedzwa kwepamusoro, uye kupindira pakati pematanho kudiki.
Zvisinei, sezvo nhamba yemanode inowedzera, tafura yekufambisa uye ruzivo rwebasa rwakachengetwa mune node imwe neimwe inowedzera, mutoro wetiweki unowedzera, uye hurongwa hwekutonga kwepamusoro hunowedzera zvakanyanya, zvichiita kuti hurongwa huve hwakaoma kudzora uye huchida kuparara.
Nokudaro, chirongwa chepurani hachikwanisi kuva nenhamba yakawanda yemanodhi panguva imwe chete, zvichiita kuti pave nekushaya simba uye inokodzera chete madiki-scale MESH network.
Clustering Structure
Iyo yekubatanidza dhizaini ndeyekukamura drone node kuita akati wandei akasiyana ma-sub-network zvinoenderana nemabasa avo akasiyana. Mune imwe neimwe sub-network, kiyi node inosarudzwa, iyo basa nderekushanda sekuraira kwekuraira kweiyo sub-network uye kubatanidza dzimwe node mune network.
Iwo makiyi node ega ega-network mune yekubatanidza chimiro akabatana uye anotaurirana kune mumwe nemumwe. Kutsinhana kwemashoko pakati peasina-kiyi node inogona kuitwa kuburikidza neakakosha node kana zvakananga.
Makiyi node uye asiri makiyi node eiyo sub-network pamwe chete anoumba network yekubatanidza. Zvinoenderana neakasiyana magadzirirwo emanode, inogona kukamurwazve kuita imwe-frequency clustering uye multi-frequency clustering.
(1)Single-frequency Clustering
Mune imwe-frequency clustering structure, pane ina mhando dzemanodhi mumambure, anoti cluster head/non-cluster head nodes, gateway/distributed gateway nodes. Iyo backbone link inoumbwa neye cluster head uye gedhi node. Imwe neimwe node inotaurirana neiyo yakafanana frequency.
Ichi chimiro chiri nyore uye chinokurumidza kuumba network, uye frequency bhendi yekushandisa rate zvakare yakakwirira. Nekudaro, ichi chimiro chetiweki chinotarirwa kune zvipingamupinyi zvezvishandiso, senge crosstalk pakati pematanho kana huwandu hwemanodhi munetiweki huchiwedzera.
Kuti udzivise kutadza kwekuita mishoni kunokonzerwa nekukanganiswa kwe-co-frequency, chimiro ichi chinofanira kudzivirirwa kana radius yesumbu rega rega yakafanana mune yakakura-mwero drone inozvironga network.
(2)Multi-frequency Clustering
Yakasiyana ne-single-frequency clustering, ine cluster imwe pane layer, multi-frequency clustering ine akati wandei, uye imwe neimwe layer ine akati wandei. Mune network yakabatana, network node dzinogona kukamurwa kuita masumbu akawanda. Node dzakasiyana musumbu dzakakamurwa kuita masumbu emusoro node uye sumbu nhengo node zvinoenderana nematanho avo, uye akasiyana matauriro anopihwa.
Muchikwata, nhengo dzemasumbu dzine mabasa akareruka uye hazvizowedzera zvakanyanya network routing pamusoro, asi cluster head node dzinoda kubata sumbu, uye dzine ruzivo rwakaoma rwekufambisa kuchengetedza, iyo inoshandisa simba rakawanda.
Saizvozvo, kugona kuvharika kwekutaurirana kunosiyanawo zvichienderana neakasiyana node nhanho. Iyo yakakwirira mwero, iyo yakakura yekuvharira kugona. Nekune rimwe divi, kana node iri yemazinga maviri panguva imwe chete, zvinoreva kuti node inoda kushandisa mafrequency akasiyana kuita mabasa akawanda, saka huwandu hwemafrequency hwakafanana nehuwandu hwemabasa.
Muchigadziro ichi, musoro wesumbu unotaurirana nedzimwe nhengo musumbu uye nodes mune mamwe mapeji emasumbu, uye kutaurirana kwega kwega kwega hakukanganisi. Ichi chimiro chakakodzera kuzvidzora-kuronga network pakati pehombe-scale drones. Kuenzaniswa neiyo imwechete cluster chimiro, ine zvirinani scalability, yakakwirira mutoro, uye inogona kubata yakawanda yakaoma data.
Nekudaro, nekuti iyo cluster head node inoda kugadzirisa yakawanda data, iyo simba rekushandisa inokurumidza kupfuura mamwe masumbu masumbu, saka hupenyu hwetiweki hupfupi pane imwe-frequency clustering structure. Mukuwedzera, kusarudzwa kwemasumbu emusoro wemapoka pane imwe neimwe musungo wekubatanidza hakuna kugadziriswa, uye chero node inogona kushanda semusoro wesumbu. Kune imwe node, kana ichigona kuve musoro wesumbu zvinoenderana netiweki chimiro chekusarudza kana kutanga iyo clustering mechanism. Naizvozvo, iyo network clustering algorithm inoita basa rakakosha mumambure ekubatanidza.
