Internet of Things: Building block of Smart World
Internet of things is the inter-networking of physical devices, vehicles, smart devices, buildings, and other items embedded with electronics, software, sensors, actuators with network connectivity which enable these objects to collect, process and exchange data. Internet of things (IoT) is an emerging trend nowadays and base of the smart world. Now the internet is not just used to connect with people through devices or surfing purpose. But we are stepping into smart world where everything will be connected with IoT.
IoT is providing an opportunity for incessant development of smart home to smart world with artificial intelligence and Machine learning and cloud computing. It is like not just accessing your home appliances through your phone at remote location but also controlling or operating them from remote location.
As IoT is spanning everywhere and becoming an essential part of our life. Here are the applications areas of IoT:
1)Smart Home: Internet of Things is the basic element for the transformation of home to smart home. In smart home all home appliances would be connected and you could switch on lights or AC before reaching home, lock or unlock home doors or windows from remote location. IoT plays a significant role in the upcoming evolution of the Internet, taking a vast leap in its contribution to gather, process, and distribute data that we can convert into information data or knowledge.
2)Smart City : IoT is also used in smart city project using sensors and auto detectors. IoT will improve quality of life up to great extent. IoT in smart homes can be used for traffic management, waste management, traffic control, noise and pollution control and security. Using sensors and detectors power consumption, water consumption, speed of vehicles etc can be minimized .For example, these devices can check the speed of the vehicles on the road can notify the driver to control the speed of vehicle if speed is above limit .So using this technology less road accident will occur on the road.
3)IoT in Business: IoT can be involved in any business or in any industry. By using some small devices we came to know any problem occurred in the machine. Before the problem will occur it will notify the user. For example it can be used to find the fault in the engine or need to change tyres of heavy vehicle to avoid road accidents.
4)IoT in Agriculture: IoT ensures accurate and efficient data to farmers like weather forecasts, planting, harvesting, soil quality, and availability and cost of labor etc. Accurate information reduces chances of crops being damaged. Farmers can use this information to take preventive or corrective action in advance and plan their activities accordingly.
6)Smart Retail Store: With the implementation of IoT in retail stores IoT makes it smarter. In a smart store number of retail applications are improving like mall traffic, cross selling of product, purchase of goods, precise inventory management and customer experience .IoT is enabling physical store to compete with online shopping giants and regain lost market share and attract customers into store .
7) IoT in Healthcare : Internet of things in is steadily growing in healthcare. The internet of things has many applications in healthcare like connected contact lenses, remote monitoring to smart sensors and medical device integration. It has the potential to keep patients safe and healthy and to improve physicians deliver care services . With IoT in healthcare patient engagement and satisfaction increases by allowing patients to spend more time interacting with their doctors.
We have discussed applications of IoT but like everything else in life there is a downside of IoT so here are the challenges of IoT:
1)Security: With the increase in the connected devices over the internet the interest of hackers will increase to harm user’s sensitive information. To secure sensitive data like locker password, health record from evil deed is the biggest challenge .
2)Connectivity: To connect hundreds or thousands of devices on centralized cloud is easy but situation will be tough to connect billion or trillion of random smart devices which will definitely increase size of the IoT network.
3)Compatibility: In order to deploy and connect different platform dependent devices some compatibility issues will be raised and to tune those issues certain common standardized protocols will need to be set.
