He aha ke ʻano o ka pūnaewele ad hoc uila
ʻO kahi pūnaewele Ad Hoc, ʻike ʻia hoʻi ʻo ka mobile ad hoc network (MANET), he pūnaewele hoʻonohonoho ponoʻī o nā polokalamu kelepona hiki ke kamaʻilio me ka hilinaʻi ʻole ʻana i kahi ʻōnaehana mua a i ʻole kahi hoʻokele kikowaena. Hoʻokumu ʻia ka pūnaewele me ka ikaika i ka hele ʻana o nā mea i loko o ka laulā o kekahi, e ʻae iā lākou e hoʻololi i ka ʻikepili peer-to-peer.
He aha nā hiʻohiʻona o ka pūnaewele ad hoc uila?
Loaʻa i nā ʻupena ad hoc uila, ʻike ʻia hoʻi ʻo nā pūnaewele hoʻonohonoho ponoʻī uea, nā hiʻohiʻona ʻokoʻa e hoʻokaʻawale iā lākou mai nā pūnaewele kamaʻilio kuʻuna. Hiki ke hōʻuluʻulu ʻia kēia mau ʻano penei:
Decentralized a me ka hoʻonohonoho ponoʻī
- Hoʻokaʻawale ʻia nā pūnaewele ad hoc ueaʻole i ke ʻano, ʻo ia hoʻi, ʻaʻohe node mana kikowaena a i ʻole nā mea hana e pono ai no kā lākou hana.
- Ua like ke kūlana o nā nodes i loko o ka pūnaewele a hiki ke kamaʻilio pololei me kekahi me ka hilinaʻi ʻole i kahi kahua kumu a i ʻole ke kikowaena kikowaena.
- Hoʻonohonoho ponoʻī a hoʻonohonoho ponoʻī ka pūnaewele, e ʻae iā ia e hana a hoʻololi i nā loli i ke kaiapuni a me nā wahi node.
Dynamic Topology
ʻO ka topology pūnaewele (ka hoʻonohonoho ʻana o nā nodes a me ko lākou mau pili) i kahi ʻoihana ad hoc uea ʻole he ikaika loa.
Hiki ke neʻe wale nā nodes, e hoʻololi pinepine i nā pilina ma waena o lākou.
Pono kēia dynamicity i nā algorithms routing hiki ke hoʻololi koke i nā loli i ka topology pūnaewele a mālama i ka pilina.
Alanui Nui-Hop
- Ma kahi pūnaewele ad hoc ueaʻole, hiki ʻole i nā node ke kamaʻilio pololei me kekahi i kekahi ma muli o ka palena palena o ka hoʻouna ʻana.
- No ka lanakila ʻana i kēia palena, hilinaʻi nā nodes i ka hoʻokele multi-hop, kahi e hoʻouna ʻia ai nā memo mai kekahi node ai kekahi a hiki i ko lākou wahi e hele ai.
- ʻO kēia ka mea e hiki ai i ka pūnaewele ke uhi i kahi ʻāpana nui a mālama i ka pilina ʻoiai inā ʻaʻole nā nodes i loko o ke kikowaena kamaʻilio pololei.
ʻO ka Bandwidth palena a me nā kumuwaiwai
- Loaʻa i nā alaloa kamaʻilio ʻole i ka bandwidth liʻiliʻi, hiki ke kaohi i ka nui o ka ʻikepili i hiki ke hoʻouna ʻia i kēlā me kēia manawa.
- Eia hou, hiki i nā nodes i loko o kahi pūnaewele ad hoc uea ʻole ke loaʻa ka mana a me ka hiki ke hoʻoponopono, e kāohi hou ana i nā kumuwaiwai o ka pūnaewele.
- He mea koʻikoʻi ka hoʻohana pono ʻana i kēia mau kumuwaiwai liʻiliʻi no ka mālama ʻana i ka hana pūnaewele a me ka hilinaʻi.
Kūlana Kūikawā a Ad Hoc
Hoʻohana pinepine ʻia nā pūnaewele ad hoc ueaʻole no nā kumu kikoʻī, no ka manawa pōkole, e like me ke kōkua ʻana i ka pōʻino, nā hana pūʻali koa, a i ʻole nā hanana pōkole.
Hiki ke hoʻonohonoho koke ʻia a wāwahi ʻia e like me ka mea e pono ai, e hoʻololi pono iā lākou i nā kūlana hoʻololi.
Nā pilikia palekana
ʻO ke ʻano decentralized a me ka ikaika o nā ʻupena ad hoc uea e hōʻike i nā pilikia palekana kūʻokoʻa.
ʻAʻole maikaʻi paha nā hana palekana kuʻuna, e like me nā pale ahi a me nā ʻōnaehana ʻike intrusion, i kēia mau pūnaewele.
Pono nā protocols palekana a me nā algorithms e pale i ka pūnaewele mai ka hoʻouka ʻana a mālama i ka pilikino ʻikepili a me ka pololei.
Hiki i nā pūnaewele ad hoc uea ʻole ke komo i nā node me nā mana like ʻole, e like me ka hoʻololi ʻana i nā pae hoʻouna, ka mana hana, a me ke ola pākaukau.
Pono kēia heterogeneity i nā algorithms a me nā protocols e hiki ke hoʻololi i nā ʻano like ʻole o nā nodes i ka pūnaewele.
Heterogeneity
Hiki i nā pūnaewele ad hoc uea ʻole ke komo i nā node me nā mana like ʻole, e like me ka hoʻololi ʻana i nā pae hoʻouna, ka mana hana, a me ke ola pākaukau.
Pono kēia heterogeneity i nā algorithms a me nā protocols e hiki ke hoʻololi i nā ʻano like ʻole o nā nodes i ka pūnaewele.
I ka hōʻuluʻulu ʻana, ʻike ʻia nā pūnaewele ad hoc uila e kā lākou decentralization, hoʻonohonoho ponoʻī, topology dynamic, multi-hop routing, palena bandwidth a me nā kumuwaiwai, ka manawa a me ke ʻano ad hoc, nā pilikia palekana, a me ka heterogeneity. Ua kūpono kēia mau hiʻohiʻona iā lākou no ka nui o nā noi, e like me nā hana pūʻali koa, kōkua pōʻino, a me nā hanana manawa pōkole, kahi i loaʻa ʻole ai nā ʻoihana kamaʻilio kuʻuna.
