DZIWANI ZOTHANDIZA padziko lonse za njira zolankhulirana

Ulusi: ndi ipv6-based, low-power mesh networking teknoloji yopangidwa kuti ipereke mauthenga otetezeka, opanda msoko pazida za intaneti ya Zinthu.Poyambirira adapangidwa kuti azigwiritsidwa ntchito panyumba mwanzeru komanso kupanga makina opangira makina, kuwongolera kutentha, kugwiritsa ntchito mphamvu, kuyatsa, chitetezo, ndi zina zambiri, Thread yakulitsa kuchuluka kwake kuti iphatikize ntchito zambiri za intaneti ya Zinthu.Chifukwa Thread imagwiritsa ntchito teknoloji ya 6LoWPAN ndipo imachokera ku IEEE 802.15.4 mesh networking protocol, Thread imakhalanso ndi IP address, yomwe imapereka kulankhulana bwino pakati pa zipangizo zotsika mtengo, zogwiritsira ntchito batri komanso mtambo ndi AES encryption.

Pofuna kupititsa patsogolo kutchuka kwa protocol ya Thread, Nest Labs (yothandizira Alphabet/Google), Samsung, ARM, Qualcomm, NXP Semiconductor/Freescale, Silicon Labs ndi makampani ena anapanga mgwirizano wa "Thread Group" mu July 2014. Kulimbikitsa Thread ngati muyezo wamakampani ndikupereka ziphaso za Thread pazogulitsa zamabizinesi.

Bulutufi:Muyezo waukadaulo wopanda zingwe womwe umagwiritsa ntchito 2.4-2.485 GHz ISM band UHF mafunde a wayilesi, kutengera mapaketi a data, okhala ndi kasamalidwe ka kapolo, kuti azindikire kusinthana kwa data patali pakati pa zida zokhazikika, zida zam'manja ndikumanga maukonde amunthu.Imayendetsedwa ndi Bluetooth Technology Alliance (SIG), IEEE imatchula ukadaulo wa Bluetooth ngati IEEE 802.15.1, koma sikusunganso muyezo ndipo ili ndi netiweki ya ma patent omwe angaperekedwe ku zida zomwe zikugwirizana.Bluetooth imagwiritsa ntchito ukadaulo wodumphadumpha pafupipafupi kuti igawanitse zomwe zimatumizidwa m'mapaketi omwe amatumizidwa padera pa mayendedwe 79 osankhidwa a Bluetooth.Njira iliyonse ili ndi bandwidth ya 1 MHz.Bluetooth 4.0 imagwiritsa ntchito 2 MHz phula ndipo imatha kukhala ndi ma mayendedwe 40.Batire yamtundu wabwino wopanda zingwe ya Bluetooth imatha zaka 2-3, nthawi zambiri masabata angapo.

Ukadaulo wa Wi-SUN (Wireless Smart Ubiquitous Network) wakhazikika pamiyezo yotseguka ya IEEE 802.15.4g, IEEE 802, ndi IETF IPv6.Wi-SUN FAN ndi protocol ya netiweki ya mesh yokhala ndi maukonde ad-hoc komanso ntchito zodzichiritsa.Chida chilichonse pamanetiweki chimatha kulumikizana ndi anansi ake, ndipo mauthenga amatha kuyenda mtunda wautali kwambiri pakati pa node iliyonse pamaneti.Ukadaulo wopatsirana wa Wi-SUN umadziwika ndi kufalikira kwakutali, chitetezo, scalability yayikulu, kulumikizana, kumanga kosavuta, maukonde a Mesh, komanso kugwiritsa ntchito mphamvu zochepa (Module ya Wi-SUN ya batri ingagwiritsidwe ntchito kwa zaka khumi).Amagwiritsidwa ntchito kwambiri pazida zoyankhulirana monga ma smart magetsi mita ndi ma controller home intelligent energy management (HEMS).Zimathandizanso kupanga intaneti yayikulu kwambiri yazinthu.

Kutengera zonsezi palimodzi, tikuganiza kuti zingakhale zothandiza kwambiri kuti makampaniwa apereke magawo afupikitsa opangira maupangiri omwe ndi osavuta kupanga ndikuwonetsa malingaliro okhudzana ndi chitetezo cha data.Pakati pa miyezo yambiri ya IEEE 802.15.4, monga ZigBee Pro, Thread ndi RF4CE, timapeza kuti Thread ili ndi mwayi wopititsa patsogolo pazifukwa zotsatirazi: (1) Mothandizidwa ndi makampani akuluakulu monga Google, Arm, ndi Samsung, Apple adagwirizana. Ulusi mu 2018. (2) IP-based protocol, kuphatikizika kwa pulogalamu yolumikizana ndi mapulogalamu ndikosavuta kukwaniritsa.(3) Zipangizo zomwe zimakhala zokhazikika kwambiri, zogwirizana kwambiri, zotetezeka kwambiri komanso zoyenera kugwiritsa ntchito batire.Zotsatirazi ndi tebulo lachiwerengero la zolosera zakukula kwa msika.

Monga mukuwonera pa tchati pamwambapa, kukhazikitsidwa kwa ma protocol okhudzana ndi IEEE 802.15.4 akuyembekezeka kupitiliza kukula, kuyang'ana pa ZigBee ndi Thread, makamaka Thread.Pankhani ya kugwiritsa ntchito, kutengera kuphatikizika kwa kafukufuku wamsika, Smart Home, Medical Devices, Auto Metering, Smart Building ndi Industrial ndizomwe zimagwiritsidwa ntchito kwambiri.
