Izixuku ze-Micro-droneInethiwekhi ye-MESH iwuhlelo lokusebenza olwengeziwe lwamanethiwekhi esikhangiso seselula emkhakheni wama-drones. Ngokuhlukile kunethiwekhi evamile ye-AD hoc yeselula, ama-network node kumanethiwekhi e-drone mesh awathintwa indawo ngesikhathi sokunyakaza, futhi isivinini sawo ngokuvamile sishesha kakhulu kunaleso samanethiwekhi eselula azihlelayo.
Isakhiwo sayo senethiwekhi sisatshalaliswa kakhulu. Inzuzo ukuthi ukukhetha umzila kuqedwa inombolo encane yama-node kunethiwekhi. Lokhu akunciphisi nje kuphela ukushintshaniswa kolwazi lwenethiwekhi phakathi kwamanodi kodwa futhi kunqoba ukonakala kokulawula umzila ophakathi nendawo.
Isakhiwo senethiwekhi ye-UAV swarmAmanethiwekhi e-MESHingahlukaniswa ngesakhiwo sepulani kanye nesakhiwo esihlangene.
Esakhiweni se-planar, inethiwekhi inokuqina okuphezulu nokuphepha, kodwa ukulinganisa okubuthakathaka, okulungele amanethiwekhi amancane okuzihlela.
Esakhiweni esihlanganisiwe, inethiwekhi inokuscalability okuqinile futhi ifaneleka kakhulu kunethiwekhi enkulu ye-drone swarm ad-hoc.
Isakhiwo sePlanar
Isakhiwo seplani sibizwa nangokuthi isakhiwo sontanga kuya kontanga. Kulesi sakhiwo, i-node ngayinye iyafana ngokuya ngokusatshalaliswa kwamandla, ukwakheka kwenethiwekhi, nokukhetha umzila.
Ngenxa yenani elilinganiselwe lama-drone node nokusabalalisa okulula, inethiwekhi inokuqina okuqinile nokuphepha okuphezulu, futhi ukuphazamiseka phakathi kweziteshi kuncane.
Kodwa-ke, njengoba inani lama-node likhula, itafula lomzila nolwazi lomsebenzi olugcinwe ku-node ngayinye luyanda, umthwalo wenethiwekhi uyanda, futhi ukulawulwa kwesistimu kukhuphuka kakhulu, okwenza uhlelo lube nzima ukulawula futhi lujwayele ukuwa.
Ngakho-ke, isakhiwo se-planar asikwazi ukuba nenani elikhulu lama-node ngesikhathi esifanayo, okuholela ekulinganisweni okubi futhi kufanelekile kuphela kumanethiwekhi amancane we-MESH.
Isakhiwo Seqoqo
Isakhiwo sokuhlanganisa siwukuhlukanisa ama-drone node abe amanethiwekhi amancane ahlukene ngokwemisebenzi yawo ehlukene. Kunethiwekhi encane ngayinye, kukhethwa i-node yokhiye, umsebenzi wayo uwukusebenza njengesikhungo sokulawula umyalo we-sub-network nokuxhuma amanye ama-node kunethiwekhi.
Amanodi ayisihluthulelo enethiwekhi encane ngayinye esakhiweni sokuhlanganisa axhunyiwe futhi ayaxhumana. Ukushintshaniswa kolwazi phakathi kwamanodi angewona okhiye kungenziwa ngama-key node noma ngokuqondile.
Amanodi angukhiye namanodi angewona okhiye ayo yonke inethiwekhi engaphansi ndawonye akha inethiwekhi ehlanganisayo. Ngokuya ngokucushwa kwe-node okuhlukene, ingabuye ihlukaniswe ibe yiqoqo lemvamisa eyodwa kanye nokuhlanganisa amafrikhwensi amaningi.
(1)I-Single-frequency Clustering
Esakhiweni sokuhlanganisa se-single-frequency, kunezinhlobo ezine zamanodi kunethiwekhi, okuyikhanda le-cluster/non-cluster head node, isango/amanodi amasango asabalalisiwe. Isixhumanisi somgogodla sakhiwe ngekhanda leqoqo kanye namanodi esango. I-node ngayinye ixhumana nemvamisa efanayo.
Lesi sakhiwo silula futhi siyashesha ukwenza inethiwekhi, futhi izinga lokusebenzisa ibhendi yefrikhwensi nalo liphakeme. Kodwa-ke, lesi sakhiwo senethiwekhi sithambekele ekubeni nezinkinga zensiza, njengokuhlangana phakathi kwamashaneli lapho inani lamanodi kunethiwekhi likhula.
Ukuze ugweme ukwehluleka kokufeza umgomo okubangelwa ukuphazamiseka kwe-co-frequency, lesi sakhiwo kufanele sigwenywe lapho i-radius yeqoqo ngalinye ifana kunethiwekhi enkulu yokuzihlela ye-drone.
(2)I-Multi-frequency Clustering
Ihlukile ekuhlanganiseni kwe-single-frequency, eneqoqo elilodwa isendlalelo ngasinye, ukuhlanganisa okunamaza amaningi kuqukethe izendlalelo ezimbalwa, futhi isendlalelo ngasinye siqukethe amaqoqo amaningana. Kunethiwekhi ehlanganisiwe, amanodi enethiwekhi angahlukaniswa abe amaqoqo amaningi. Ama-node ahlukene kuqoqo ahlukaniswe ama-cluster head node nama-cluster member node ngokwamazinga awo, futhi amafrikhwensi okuxhumana ahlukene ayabelwe.
Ku-cluster, ama-node amalungu eqoqo anemisebenzi elula futhi ngeke akhulise kakhulu umzila wenethiwekhi, kodwa ama-node ekhanda leqoqo adinga ukuphatha iqoqo, futhi abe nolwazi oluyinkimbinkimbi lomzila ukuze lugcinwe, oludla amandla amaningi.
Ngokufanayo, amakhono okuxhumana nawo ayahlukahluka ngokuya ngamazinga ahlukene wama-node. Izinga eliphakeme kakhulu, amandla amakhulu okukhava. Ngakolunye uhlangothi, uma i-node ingeyamazinga amabili ngesikhathi esisodwa, kusho ukuthi i-node idinga ukusebenzisa amafrikhwensi ahlukene ukwenza imisebenzi eminingi, ngakho inani lamafrikhwensi liyafana nenani lemisebenzi.
Kulesi sakhiwo, inhloko yeqoqo ixhumana namanye amalungu ku-cluster nama-nodes kwezinye izingqimba zamaqoqo, futhi ukuxhumana kwesendlalelo ngasinye akuphazamisi. Lesi sakhiwo silungele amanethiwekhi azihlelayo phakathi kwama-drones amakhulu. Uma iqhathaniswa nesakhiwo seqoqo elilodwa, inokukalwa okungcono, umthwalo ophakeme, futhi ingakwazi ukuphatha idatha eyinkimbinkimbi.
Kodwa-ke, ngenxa yokuthi i-cluster head node idinga ukucubungula inani elikhulu ledatha, ukusetshenziswa kwamandla kuyashesha kunamanye ama-cluster node, ngakho-ke impilo yenethiwekhi ifushane kunesakhiwo sokuhlanganisa i-single-frequency. Ukwengeza, ukukhethwa kwama-node ekhanda leqoqo kungqimba ngayinye kunethiwekhi yokuhlanganisa akulungisiwe, futhi noma iyiphi i-node ingasebenza njengenhloko yeqoqo. Ku-node ethile, ukuthi ingaba inhloko yeqoqo kuncike esakhiweni senethiwekhi ukuze sinqume ukuthi kuqalwe yini indlela yokuhlanganisa. Ngakho-ke, i-algorithm yokuhlanganisa inethiwekhi idlala indima ebalulekile kunethiwekhi yokuhlanganisa.
