Internet of Things
The internet of things (IoT) refers to the millions of devices all over the world that connected to the internet and sharing and collecting data. Thanks to the cheap super computers and the super-fast wireless internet connections.
There is huge broad range of things that falls under that category: Internet-connected to the new version of home applications, busses, air planes, just like every device with electronic chip on. Gadgets like Alexa, Cortana are only exist because of this technology.
With internet of things its more easy to works with data processing and data analyzing. Specially with this tech people can interact with global information network without key board, mouse or screen. Many of their daily activities and appliances can take instructions from that network with minimal interactions.
By using Internet of Things with industrials, people are able to bring same efficiency to the physical manufacturing and distribution. Millions of internet-embedded devices and sensors worldwide are providing the rich data. Companies can gather the data to increase their safety of their operations, track assets and also reduce manual process. Also who have inters it peoples references and behavior, can also gather data. And that will be a huge privacy issue.
There is over 50 Billion internet of things based devices all over the world in 2020. And those devices generated 4.4 zettabites of data last year (1ZB= 1000 000 000 000 GB) . Comparison with 2013 IoT device generated mere 100 billion gigabits. Estimated value on this market in 2025 is in range of 1.6 $ trillion to 14.4$ trillion.
History of Internet of Things
A world of omnipresent connected device and a sensor is the one of oldest device in internet of things. Internet of Things lore has enabled at vending machine at Carnegie Mellon that is connected to the APRANET in 1970 is the first Internet of Things device. Also many technologies have touched as Internet of things characteristics to give them a futuristic experience. But the term of Internet of Things coined at 1999 by British technologist Kevin Ashton.
At first the technology lagged behind the vision with present technologies. Every internet-connected device needed a processer to communicate with other things. And those devices require lot more power and cost that makes that is very hard to use. Then Moor’s law came up in mid-2000.
One millstone is widespread adoption of RFID tags. To use those people intend because those are cheap transponders, Could stuck any project to connect it to the large network. Omnipresent Wi-Fi and 4G made it to the designers to design with simple and connect to Wi-Fi on anywhere. With IP version 6 (IPv6) they could connect with billions of gadgets to the internet.
How does Internet of Things Work
The basic task of internet of things is gather data. They are internet connect devices, so they must have an IP address. And they range in complexity form autonomous vehicle to simple temperature sensor in that factory. They also include in personal device like smart watch to track that can monitor how many steps he have taken, how many calories burnt and what is heart rate on that person. To make that data useful they need to process that data, analyze the data and also filter them. Then that data can be handl in many ways.
Collecting data is done by transfer data in the device to the collecting point. Transferring the data can be done in various ways in wireless or wired. The data can be sent on to the cloud or to the data center through the internet. Or it can be arrange step by step using some processing power and storage capacity before data send. Processing the data is done by processing centers or in cloud, but lot of time that’s not an option. In some cases like shutoffs in industries delaying the sending data to the remote data center is too great. The round trip time of sending data, analyzing time, processing time and also returning instructions can takes too long. So the system will not work online-real time. In such cases EDGE computing can come to play. With smart EDGE device can aggregate data, analyze it and quick responses if necessary. And EDGE devices also have a up streaming connection to send data to further process and store.
Internet of things Uses
Anything that’s capable of gathering data from physical world and send them back to home is in this category. RFID tags, home applications and sensors that use in industries that using Artificial Intelligence and Machine learning are this category. These sensors can monitor range of factors including temperature, humidity, pressure, use of power and many capabilities.Other kind of IoT devices is wearables and home security systems. Also these are generic devices like Arduino and RaspberyPI lets to build your own IoT points.
Security and Privacy Issues
IoT devices lack the capacity to be patch, which means they are always vulnerable. Hackers are aggressively targeting IoT devices like routers and cameras because their inherent lack of security makes them easier to corrupt and aggregate into massive botnets.
Internet of Things has earned a bad reputation when it comes to security. They are design for individual tasks and minimal human interaction. And also cannot upgrade, patched or monitored. IoT customers can improve their security. Also, vendors need to make IoT devices more secure and easier to keep secure if they are going to be in the field long time.
