1 Internet of Things  What is IOT? 2 ❖ The Internet of Things is the network of physical objects or "things" embedded with electronics, software, sensors, and network connectivity, which enables these objects to collect and exchange data. ❖ It allows objects to be sensed and controlled remotely across existing network infrastructure, creating opportunities for more direct integration between the physical world and computer-based systems, and resulting in improved efficiency, accuracy and economic benefit.  3 ❖ "Things," in the IoT sense, can refer to a wide variety of devices such as heart monitoring implants, biochip transponders on farm animals, electric clams in coastal waters, automobiles with built-in sensors, DNA analysis devices for environmental/food/pathogen monitoring or field operation devices that assist fire-fighters in search and rescue operations. ❖ These devices collect useful data with the help of various existing technologies and then autonomously flow the data between other devices. Where are we now in 2021 ? IoT ecosystem Ecosystem components  Device manufacturers IoT  Sensors/actuators, smart appliances  Network service providers  Operators, NMS providers  Cloud service providers  Data centres, dBase, dWarehouse  Platform providers  Middleware providers, SDKs App  3rd party application developers  Analytics providers, tools, APIs Example  General Electric (GE) deploys sensors in its jet engines, turbines, and wind farms.

Radio-frequency identification (RFID) was seen as a prerequisite for the IoT at that point. If all objects and people in daily life were equipped with identifiers, computers could manage and inventory them. Besides using RFID, the tagging of things may be achieved through such technologies as near field communication, barcodes, QR codes, blue-tooth, and digital watermarking.  How IOT Works? 11 Internet of Things is not the result of a single novel technology; instead, several complementary technical developments provide capabilities that taken together help to bridge the gap between the virtual and physical world. These capabilities include: Communication and cooperation Addressability Identification Sensing Actuation Embedded information processing Localization User interfaces  How IoT Works? RFID Sensor Smart Tech Nano Tech To identify To collect To enhance To make the and track and process the power of smaller and the data the data to the network smaller of things detect the by devolving things have changes in processing the ability to the physical capabilities to connect and status of different part interact. things of the network. 12  The Structure of IoT 13 The IoT can be viewed as a gigantic network consisting of networks of devices and computers connected through a series of intermediate technologies where numerous technologies like RFIDs, wireless connections may act as enablers of this connectivity. Tagging Things : Real-time item traceability and addressability by RFIDs. Feeling Things : Sensors act as primary devices to collect data from the environment. Shrinking Things : Miniaturization and Nanotechnology has provoked the ability of smaller things to interact and connect within the “things” or “smart devices.” Thinking Things : Embedded intelligence in devices through sensors has formed the network connection to the Internet. It can make the “things” realizing the intelligent control. Current Status & Future Prospect of IoT 14 “Change is the only thing permanent in this world”  IoT as a Network of Networks: 15 These networks connected with added security, analytics, and management capabilities. This will allow IoT to become even more powerful in what it can help people achieve.  16 Knowledge Management – Turning Data into Wisdom The more data that is created, the better understanding and wisdom people can obtain.  The Future of IoT 17 "The Sky's not the limit. It's only the beginning with IoT."  The Potential of IoT 18 GE’s estimates on potential of just ONE percent savings applied using IoT across global industry sectors.  19 Unlock the Massive potential of IoT Technology roadmap of IoT 20  Applications of IoT 21 "The Ultimate Goal of IOT is to Automate Human Life."  Few Applications of IoT 22 ✓ Building and Home automation ✓ Manufacturing ✓ Medical and Healthcare systems ✓ Media ✓ Environmental monitoring ✓ Infrastructure management ✓ Energy management ✓ Transportation ✓ Better quality of life for elderly ✓......... You name it, and you will have it in IoT! 23 24 25  Sensors in even the holy cow! 26 In the world of IoT, even the cows will be connected and monitored. Sensors are implanted in the ears of cattle. This allows farmers to monitor cows’ health and track their movements, ensuring a healthier, more plentiful supply of milk and meat for people to consume. On average, each cow generates about 200 MB of information per year. 27 28  29 IoT helps you in LIFE LOGGING 30  TECHNOLOGICAL CHALLENGES OF IOT At present IoT is faced with many challenges,31 such as: ▪ Scalability ▪ Technological Standardization ▪ Inter operability ▪ Discovery ▪ Software complexity ▪ Data volumes and interpretation ▪ Power Supply ▪ Interaction and short range communication ▪ Wireless communication ▪ Fault tolerance 32  Criticisms and Controversies of IoT 33 Scholars and social observers and pessimists have doubts about the promises of the ubiquitous computing revolution, in the areas as: ▪ Privacy ▪ Security ▪ Autonomy and Control ▪ Social control ▪ Political manipulation ▪ Design ▪ Environmental impact ▪ Influences human moral decision making 34  References 35 1. www.google.com 2. https://en.wikipedia.org/wiki/Internet_of_Things 3.
