pros and cons
Advantages-disadvantages of IoT
Since IoT has communication between devices, in which physical devices are able to stay connected and hence the total transparency is available with lesser inefficiencies and greater quality.
Automation and Control
Without human involvement, machines are automating and controlling vast amount of information, which leads faster and timely output.
Monitoring saves money and time
Since IOT uses smart sensors to monitor various aspects in our daily life for various applications which saves money and time.
Better Quality of Life
IoT based applications increases comfort and better management in our daily life; thereby improving the quality of life.
As devices from different manufacturers will be interconnected in IoT, presently , there is no international standard of compatibility for the tagging and monitoring equipment.
The IoT is a diverse and complex network. Any failure or bugs in the software or hardware will have serious consequences. Even power failure can cause a lot of inconvenience.
IoT has involvement of multiple devices and technologies and multiple companies will be monitoring it. Since lot of data related to the context will be transmitted by the smart sensors, there is a high risk of losing private data. 5.2.3 Lesser employment of menial staff: With the advent of technology, daily activities are getting automated by using IoT with less human intervention, This causes unemployment issue inthe society.
Technology Takes Control of Life Our lives will be increasingly controlled by technology, and will be dependent on it. We have to decide how much of our daily lives are we willing to mechanize and be controlled by technology. Storage Volume
Based on the scenario and context, smart objects collect either small amount of data or huge volume of data. So based on amount of data, storage has to be allocated.
It‘s very important to interpret the context, that sensor has to sense. Context has important role for generating useful information and to draw a conclusion from the data sent by the sensors.
Security and personal privacy
In IoT, network formed by smart objects via internet, so
providing security and privacy is a big challenge. In IoT, sometimes user prevent other user to access some particular information at certain time or preventing some communication or some transaction to protect secrete information from competitors. So handling all this situation is a big challenge.
the top 5 IoT use cases
Whenever we think of IoT systems, the most important and efficient application that stands out is the smart home. The number of people searching for smart homes increases every month by about 60,000 people. Another interesting thing is that the database of smart homes for IoT analytics includes 256 companies and startups. More companies are now actively involved in smart home. The estimated amount of funding for smart home startups exceeds $2.5 billion and growing at a rapid rate.
Just like smart homes, wearables remain a hot topic among potential IoT. Every year, consumers all across the globe await the release of the latest Apple smartwatch. Apart from this, there are plenty of other wearable devices that make our life easy.
Smart cities, like its name suggests, is a big innovation and spans a wide variety of use cases, from water distribution and traffic management to waste management and environmental monitoring. The reason why it is so popular is that it tries to remove the discomfort and problems of people who live in cities. IoT solutions offered in the smart city sector solve various city-related problems, comprising of traffic, reducing air and noise pollution, and helping to make cities safer.
Connected car technology is a vast and an extensive network of multiple sensors, antennas, embedded software, and technologies that assist in communication to navigate in our complex world. It has the responsibility of making decisions with consistency, accuracy, and speed. It also has to be reliable. These requirements will become even more critical when humans give up control of the steering wheel and brakes to the autonomous vehicles that are being tested on our highways right now
Connected Health (Digital Health/Telehealth/Telemedicine)
IoT has various application in healthcare which are from remote monitoring equipment to advance and smart sensors to equipment integration. It has the potential to improve how physicians deliver care and also keep patients safe and healthy. Healthcare IoT can allow patients to spend more time interacting with their doctors, which can boost patient engagement and satisfaction. From personal fitness sensors to surgical robots, IoT in healthcare brings new tools updated with the latest technology in the ecosystem that helps in developing better healthcare. IoT helps to revolutionize healthcare and provide pocket-friendly solutions for both the patient and healthcare professional.
History of IoT
The Internet of Things, as a concept, wasn’t officially named until 1999. One of the first examples of an Internet of Things is from the early 1980s, and was a Coca Cola machine, located at the Carnegie Melon University. Local programmers would connect by Internet to the refrigerated appliance, and check to see if there was a drink available, and if it was cold, before making the trip.By the year 2013, the Internet of Things had evolved into to a system using multiple technologies, ranging from the Internet to wireless communication and from micro-electromechanical systems (MEMS) to embedded systems. The traditional fields of automation (including the automation of buildings and homes), wireless sensor networks, GPS, control systems, and others, all support the IoT.
The Internet of Things (IoT):
Is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers (UIDs) and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.
Network without requiring human-to-human or human-to-computer interaction.
The definition of the Internet of Things has evolved due to the convergence of multiple technologies, real-time analytics, machine learning, commodity sensors, and embedded systems. In the consumer market, IoT technology is most synonymous with products pertaining to the concept of the "smart home", covering devices and appliances(such as lighting fixtures, thermostats, home security systems and cameras, and other home appliances) that support one or more common ecosystems, and can be controlled via devices associated with that ecosystem, such as smartphones and smart speakers.
There are a number of serious concerns about dangers in the growth of IoT, especially in the areas of privacy and security; and consequently industry and governmental moves to begin to address these.
How it works
How it works?
First, sensors or devices collect data from their environment. This could be as simple as a temperature reading or as complex as a full video feed.
Next, that data is sent to the cloud, but it needs a way to get there!
The sensors/devices can be connected to the cloud through a variety of methods including: cellular, satellite, WiFi, Bluetooth, low-power wide-area networks (LPWAN), or connecting directly to the internet via ethernet.
3) Data Processing
Once the data gets to the cloud, software performs some kind of processing on it.
This could be very simple, such as checking that the temperature reading is within an acceptable range. Or it could also be very complex, such as using computer vision on video to identify objects (such as intruders in your house).
But what happens when the temperature is too high or if there is an intruder in your house? That’s where the user comes in.
4) User Interface
Next, the information is made useful to the end-user in some way. This could be via an alert to the user (email, text, notification, etc). For example, a text alert when the temperature is too high in the company’s cold storage.
Also, a user might have an interface that allows them to proactively check in on the system. For example, a user might want to check the video feeds in their house via a phone app or a web browser.
However, it’s not always a one-way street. Depending on the IoT application, the user may also be able to perform an action and affect the system. For example, the user might remotely adjust the temperature in the cold storage via an app on their phone.
And some actions are performed automatically. Rather than waiting for you to adjust the temperature, the system could do it automatically via predefined rules. And rather than just call you to alert you of an intruder, the IoT system could also automatically notify relevant authorities.
