Thread: ipv6-yakavakirwa, yakaderera-simba mesh networking tekinoroji yakagadzirirwa kupa yakachengeteka, isina musono kutaurirana kweInternet yezvinhu zvishandiso.Pakutanga yakagadzirirwa smart imba uye kuvaka otomatiki zvikumbiro senge manejimendi emidziyo, kutonga tembiricha, kushandiswa kwesimba, mwenje, chengetedzo, nezvimwe, Thread yakawedzera chiyero chayo kuti ibatanidze yakakura Internet yezvinhu zvikumbiro.Nekuti Thread inoshandisa 6LoWPAN tekinoroji uye yakavakirwa paIEEE 802.15.4 mesh networking protocol, Thread zvakare IP addressable, inopa kutaurirana kwakanaka pakati pezvinodhura, bhatiri-powered zvishandiso pamwe negore uye AES encryption.
Kuitira kuti kukurumidze kukurumbira kweThread protocol, Nest Labs (rimwe divi reAlphabet/Google), Samsung, ARM, Qualcomm, NXP Semiconductor/Freescale, Silicon Labs nemamwe makambani akaumba “Thread Group” mubatanidzwa muna Chikunguru 2014. Kukurudzira. Thread seyakajairwa indasitiri uye inopa Thread certification yenhengo bhizinesi zvigadzirwa.
Bluetooth:Iyo isina waya tekinoroji chiyero inoshandisa 2.4-2.485 GHz ISM bhendi UHF redhiyo mafungu, zvichibva pamapakeji edata, ane master-muranda architecture, kuona kureba-pfupi kuchinjanisa data pakati pezvishandiso zvakagadziriswa, nharembozha uye kuvaka dhairekitori remunhu.Inotungamirirwa neBluetooth Technology Alliance (SIG), IEEE inonyora tekinoroji yeBluetooth seIEEE 802.15.1, asi haichagadzirisi mwero uye ine network yematendi anogona kupihwa kumidziyo inoenderana.Bluetooth inoshandisa tekinoroji-hopping tekinoroji kupatsanura data rakafambiswa kuita mapaketi anofambiswa zvakasiyana pamusoro pe79 yakasarudzwa nzira dzeBluetooth.Imwe neimwe chiteshi ine bandwidth ye1 MHz.Bluetooth 4.0 inoshandisa 2 MHz pitch uye inogona kugadzirisa 40 chiteshi.Yemhando yakanaka isina waya yeBluetooth headset bhatiri ichagara makore 2-3, kazhinji mavhiki mashoma.
Wi-SUN (Wireless Smart Ubiquitous Network) tekinoroji yakavakirwa pane yakavhurika yakatarwa yeIEEE 802.15.4g, IEEE 802, uye IETF IPv6 zviyero.Wi-SUN FAN ndeye mesh network protocol ine ad-hoc networking uye yekuzviporesa mabasa.Chishandiso chega chega chiri munetiweki chinogona kutaurirana nevavakidzani vayo, uye mameseji anogona kufamba madaro marefu pakati peimwe node mune network.Wi-SUN transmission tekinoroji inoratidzwa nekutepfenyura kure, chengetedzo, yakakwirira scalability, interworking, nyore kuvaka, Mesh network, uye yakaderera simba rekushandisa (Wi-SUN module bhatiri hupenyu hunogona kushandiswa kwenguva yakareba semakore gumi).Inoshandiswa zvakanyanya mumidziyo yekutaurirana senge smart magetsi metres uye imba ine hungwaru simba manejimendi (HEMS) controller.Zvinobatsirawo kuvaka nzvimbo yakakura-yakakura-yeInternet yezvinhu.
Tichitora zvese izvi pamwe chete, isu tinofunga zvingabatsira zvakanyanya kuindasitiri kupa seti yepfupi kureferensi dhizaini mamodule ari nyore kugadzira uye anoratidza data kutaurirana kuchengetedza kufunga.Pakati pezvakawanda zveIEEE 802.15.4 zviyero, seZigBee Pro, Thread uye RF4CE, tinoona Thread ine mukana mukuru wekusimudzira nekuda kwezvikonzero zvinotevera: (1) Inotsigirwa nemakambani makuru akadai seGoogle, Arm, uye Samsung, Apple yakabatana. Thread muna 2018. (2) IP-based protocol, kubatanidzwa kwepurogiramu yekukurukurirana kwepurogiramu iri nyore kwazvo kuwana.(3) Zvishandiso zvakamisikidzwa zvakanyanya, zvinopindirana zvakanyanya, zvakachengeteka zvakanyanya uye zvakakodzera bhatiri powered mode.Inotevera tafura yehuwandu yekufanotaura kwekuvandudza kwemusika.
Sezvaunogona kuona kubva pane chati iri pamusoro, kugamuchirwa kwezvibvumirano zvine chokuita neIEEE 802.15.4 zvinotarisirwa kuramba zvichikura, zvichitarisa paZigBee uye Thread, kunyanya Thread.Panyaya yekushandiswa, maererano nekubatanidzwa kwedata reongororo yemusika, Smart Home, Medical Devices, Auto Metering, Smart Building uye Industrial ndiyo mikuru yekushandisa minda.
