Iidrone ezincinci zemibhobhoInethiwekhi ye-MESH sisicelo esongezelelweyo sothungelwano lwe-ad-hoc ephathwayo kwindawo yeedrones. Ngokwahlukileyo kwinethiwekhi ye-AD hoc eqhelekileyo, iindawo zenethiwekhi kuthungelwano lwe-drone mesh azichatshazelwa yi-terrain ngexesha lokuhamba, kwaye isantya sazo sikhawuleza kakhulu kuneso sothungelwano lwemveli oluzilungelelanisayo.
Ubume bayo benethiwekhi busasazwa kakhulu. Inzuzo kukuba ukhetho lomzila lugqitywe ngamanani amancinci kwinethiwekhi. Oku akuncitshi kuphela utshintshiselwano lolwazi lwenethiwekhi phakathi kweendawo zeendawo zokuhlala kodwa kwakhona koyisa ukungalungi kolawulo lwendlela ephakathi.
Ubume benethiwekhi ye-UAV swarmUthungelwano lwe-MESHinokwahlulwa ibe yiplani yesakhiwo kunye nesakhiwo esidibeneyo.
Kwisakhiwo esicwangcisiweyo, inethiwekhi inokuqina okuphezulu kunye nokhuseleko, kodwa i-scalability ebuthakathaka, efanelekileyo kuthungelwano oluncinci lokuzilungiselela.
Kwisakhiwo esidibeneyo, inethiwekhi inomlinganiselo oqinileyo kwaye ifaneleke ngakumbi kwi-drone swarm ad-hoc networking.
Ulwakhiwo olucwangcisiweyo
Ulwakhiwo olucwangcisiweyo lukwabizwa ngokuba yi-peer-to-peer structure. Kwesi sakhiwo, i-node nganye iyafana ngokubhekiselele ekuhanjisweni kwamandla, ukwakhiwa kwenethiwekhi, kunye nokukhethwa kwendlela.
Ngenxa yenani elilinganiselwe le-drone nodes kunye nokusabalalisa okulula, inethiwekhi inokuqina okuqinileyo kunye nokhuseleko oluphezulu, kwaye ukuphazamiseka phakathi kwamajelo kuncinci.
Nangona kunjalo, njengoko inani lee-nodes landa, itafile yomzila kunye nolwazi lomsebenzi olugcinwe kwi-node nganye luyanda, umthwalo wenethiwekhi uyanda, kwaye inkqubo yokulawula inkqubo inyuka ngokukhawuleza, okwenza inkqubo ibe nzima ukuyilawula kwaye ilungele ukuwa.
Ngoko ke, ulwakhiwo olucwangcisiweyo alukwazi ukuba nenani elikhulu lee-nodes ngexesha elifanayo, okubangelwa ukungahambi kakuhle kwaye kufanelekile kuphela kwiinethiwekhi ezincinci ze-MESH.
Ulwakhiwo lokuhlanganisana
Ubume bokudibanisa kukwahlula i-drone nodes kwiinethiwekhi ezahlukeneyo ezahlukeneyo ngokwemisebenzi yazo eyahlukileyo. Kwi-sub-network nganye, i-node engundoqo ikhethiweyo, umsebenzi wayo kukuba usebenze njengeziko lokulawula umyalelo we-sub-network kunye nokudibanisa ezinye iinqununu kwinethiwekhi.
Iinqununu eziphambili ze-sub-network kwisakhiwo sokudibanisa zixhunyiwe kwaye zinxibelelana omnye nomnye. Utshintshiselwano ngolwazi phakathi kwee-non-key nodes lunokwenziwa ngokusebenzisa iindawo eziphambili okanye ngokuthe ngqo.
Iindawo eziphambili kunye neendawo ezingezozitshixo zothungelwano olungaphantsi lulonke kunye zenza inethiwekhi edibeneyo. Ngokuhambelana nokucwangciswa kwee-node ezahlukeneyo, inokuthi iphinde yohlulwe ibe yi-single-frequency clustering kunye ne-multi-frequency clustering.
(1)I-Single-frequency Clustering
Kwi-single-frequency clustering structure, kukho iindidi ezine zeenodi kuthungelwano, ezizezi, i-cluster head/non-cluster head nodes, gateway/distributed gateway nodes. Ikhonkco lomqolo liqulunqwe yintloko yeqela kunye neendawo zesango. Indawo nganye inxibelelana ngamaza afanayo.
Esi sakhiwo silula kwaye sikhawuleza ukwenza inethiwekhi, kwaye izinga lokusetyenziswa kwebhendi yefrikhwensi liphezulu. Nangona kunjalo, esi sakhiwo sothungelwano sithambekele kwimithintelo yemithombo, efana ne-crosstalk phakathi kwamajelo xa inani leenodi kwinethiwekhi landa.
Ukuze ugweme ukungaphumeleli kokuphunyezwa kobuthunywa okubangelwa ukuphazamiseka kwe-co-frequency, esi sakhiwo kufuneka sigwenywe xa i-radius yeqela ngalinye ifana ne-drone enkulu-self-organizeng network.
(2)Ukuhlanganiswa kwee-Multi-frequency Clustering
Ihluke kwi-single-frequency clustering, ene-cluster enye ngokwemaleko, i-multi-frequency clustering iqulethe iileya ezininzi, kwaye uluhlu ngalunye luqulethe amaqela amaninzi. Kwinethiwekhi edibeneyo, iindawo zenethiwekhi zinokuhlulwa zibe ngamaqela amaninzi. Ii-nodes ezahlukeneyo kwi-cluster zihlulwe zibe yi-cluster head nodes kunye ne-cluster member nodes ngokwamanqanaba abo, kunye nee-frequencies ezahlukeneyo zonxibelelwano zabelwe.
Kwi-cluster, i-cluster member nodes inemisebenzi elula kwaye ayiyi kwandisa kakhulu i-network routing overhead, kodwa i-cluster head nodes kufuneka ilawule i-cluster, kwaye inolwazi olunzima ngakumbi lomzila wokugcina, odla amandla amaninzi.
Ngokufanayo, amandla okugubungela unxibelelwano nawo ayahluka ngokwamanqanaba eendawo ezahlukeneyo. Okukhona inqanaba liphezulu, kokukhona likhulu isakhono sokugquma. Kwelinye icala, xa i-node ikwimigangatho emibini ngaxeshanye, oko kuthetha ukuba i-node idinga ukusebenzisa ii-frequencies ezahlukeneyo ukwenza imisebenzi emininzi, ngoko ke inani le-frequencies lifana nenani lemisebenzi.
Kulo lwakhiwo, intloko yeqela inxibelelana namanye amalungu kwi-cluster kunye ne-nodes kwezinye iileyile zamaqela, kwaye unxibelelwano loluhlu ngalunye aluphazamisi omnye nomnye. Esi sakhiwo silungele ukuzilungiselela uthungelwano phakathi kweedrones ezinkulu. Xa kuthelekiswa nesakhiwo se-cluster eyodwa, inokulinganisa okungcono, umthwalo ophezulu, kwaye inokusingatha idatha enzima ngakumbi.
Nangona kunjalo, ngenxa yokuba i-node yentloko ye-cluster idinga ukucubungula inani elikhulu ledatha, ukusetyenziswa kwamandla kukhawuleza kunamanye ama-cluster nodes, ngoko ke ubomi benethiwekhi bufutshane kunesakhiwo sokuhlanganiswa kwee-frequency single. Ukongezelela, ukukhethwa kweentloko ze-cluster head nodes kwinqanaba ngalinye kwinethiwekhi ye-clustering ayilungiswanga, kwaye nayiphi na i-node inokusebenza njengentloko yeqela. Kwindawo ethile, nokuba inokuba yintloko yeqela kuxhomekeke kubume bomsebenzi wothungelwano ukwenza isigqibo sokuba iqaliswe na indlela yokudibanisa. Ngoko ke, i-algorithm yokudibanisa inethiwekhi idlala indima ebalulekileyo kwinethiwekhi yokudibanisa.
