What is the meaning of IoT – Internet of Things
What is the meaning of IoT – IoT or the internet of things is a kind of network that can connect a wider range of things through the internet via internet protocol.
IoT internet of things definition
IoT refers to interrelated computing devices including mechanical, electronic, electrical, and other devices capable to collect a variety of data, store data, process and share data via internet-based protocols in order to improve the working of various domains including health care, education, farming, other business, and home, etc.
The main aim behind the IoT is to develop a system that has smart devices that can self-report and communicate on a real-time basis to improve the efficiency of the domain and provide a quality and secure life as well as improved business.
How does the Internet of things work
Sensors are attached to the internet-connected devices to make them smart and sense the required object or data.
Devices sense the data and send the information to the cloud and processing is done through the software and decisions are taken about the next action.
Decisions may be taken by the connected devices according to the program built in the devices or alerts may be sent to the user if human intervention is required.
What are examples of the Internet of things
There are a number of examples of the Internet of things. A room fan that can be switch on or switch off via your smartphone is an example of IoT.
Camera at your main gate connected to your smartphone is also an application of smartphones. The buzzer that you can operate through your mobile is another application of IoT.
There are huge examples of IoT. IoT devices can be as simple as a child toy and as serious as driverless plain.
The most common examples or applications of the internet of things are as below-
Smart Home
A smart home is any residential building that is equipped with smart devices connected via the internet and controlled via smartphones remotely.
These devices may me electric equipment controlled via smartphone, sensors, camera, printer, plotter, televisions screens, washing machines, automatic doors, and other home appliances controlled remotely.
Smart City
A smart city refers to an innovative city equipped with the best and advanced resources that give a quality of life as well as a safe life. A smart city has water management, waste management, traffic monitoring, and management.
Smart Farming
Smart farming includes the use of advanced and best technologies to make the farming better in terms of seeds, pesticides, quality, live stocks, storage of crops and seeds, marketing of farming products, etc. in order to get quality output and maximum return from the minimum human efforts.
Smart farming emphasizes the integrated farming process also in order to use the outputs of all the phases of the farming domains in the development of more products.
Business applications
There are huge business applications of IoT for example use of IoT in transport manufacturing, management, and monitoring, smart offices to improve the working culture and employee satisfaction, etc. According to the domain of business application of the use of IoT devices may vary.
Other applications are smart retail, smart supply chain management, smart health care and medical, etc.
Why is the Internet of things important
Internet of things has become the key to quality, growth, development, and effectiveness of all the domains whether that is home, office, city, agriculture, business, etc. No business can service without the use of smart devices and the internet.
What skills are required for the Internet of things
Smart devices, internet connection is required for IoT. Also, according to the domain of interest, you must have the smartness to get the maximum from the smart devices.
Is Python good for IoT
Yes, Python is very good to design and develop the program of your interest.
Challenges in IoT applications
IoT is the foundation of revolutionary modern life that is continuously growing day by day. IoT comprises a huge number of devices connected via the internet, therefore, a big challenge is involved related to privacy and security of data, and devices.
Employing IoT application demands security and privacy on various dimensions as discussed below-
- Security of devices involved in the application domain
- Security of data stored in the cloud
- Security on information during distributed processing
- Security of information during sharing them
- Internet Security challenges
- Network security challenges, etc.
Due to the need for security and privacy requirement, there is a need to explore and research more in the field. In addition to this, there is a need to research and explore more in the cross-platform compatibility of involved components.
IoT devices
IoT devices comprise all those devices that are capable to be connected via the internet, can acquire a variety of data, share the data, process the data and use the data to facilitate a particular domain.
The list of IoT devices may be as follows-
- Laptops
- Scanners
- Microphones
- Smart Mobile phones
- RFID
- Smart toys
- Smart wearable
- Sensors
- Smart appliances.
- Smart meters,
- commercial security systems
- smart city technologies to monitor traffic and weather conditions
- Smart air conditioning,
- smart thermostats,
- smart lighting
- Smart security technologies and devices and many more
Using all these smart devices and many more devices also, various data can be collected and used to support a domain.
Therefore there are a huge number of research areas to use IoT devices and apply in the particular domain.
Some of the research topics are discussed below-
Cloud-Based IoT Framework for Ambient Assisted Living
Ambient assisted living refers to a living environment that is cared, controlled, and facilitated by the intelligent software embedded IoT devices supported by the cloud infrastructure.
These devices automatically work independently as a service provider and also work in the collection of other devices to monitor and care for the people.
Ambient assisted living means an intelligent environment to take care of people in terms of daily habits, Yoga, health, education, career, business, fashion, etc.
IoT Big Data stream processing framework for Customer Sentiment Analysis
The framework will process big data streams collected from various social media resources through chats, video, audio, text messages, to analyze customer sentiments on a domain.
The domain can be elections, shopping sites, product feedbacks, etc.
A Novel IoT-Based Smart Healthcare Framework
This is a biomedical system to support patients and users in taking support from hospitals and doctors in diagnosing health issues.
The system will not only facilitate the user in preventing and take care of health issues but also will help in monitoring health conditions online and offline remotely.
The key technologies may be RFID, wireless, sensors, and other health care devices mentioned above to get the health conditions of the users.
IoT based smart career counseling framework
The system will help in career counseling to all those students who have passed the twelfth class or graduate degree and want to pursue higher studies.
The system can have different types of tests comprising quizzes, and biometric tests to know the strength and weaknesses of the candidates for a particular career.
Remote monitoring information system based on internet of things
The system will use an internet wireless system, sensors, RFID and other biometric devices to monitor the health of people remotely to guide daily health guidance to prevent diseases.
Internet of Things based framework for rural healthcare monitoring
The system will use internet wireless system, sensors, RFID, and other biometric devices to collect physiological data of remotely located people, analyze the data to monitor the health of people remotely, to guide daily health guidance to prevent diseases.
