- 3. HISTORY OF IOT •1999- The term "Internet of Things" was used by Kevin Ashton during his work at P&G which became widely accepted •2004 - The term was mentioned in famous publications like the Guardian, Boston Globe, and Scientific American •2005-UN's International Telecommunications Union (ITU) published its first report on this topic. •2008- The Internet of Things was born •2011- Gartner, the market research company, include "The Internet of Things" technology in their research
- 4. IOT DEFINITION • “The Internet ofThings (IoT) is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to- computer interaction.” The Internet of Things (IoT) describes the network of physical objects —“things”—that are embedded with sensors, software, and other technologies for the purpose of connecting and exchanging data with other devices and systems over the internet.
- 6. What technologies have made IoT possible? • Access to low-cost, low-power sensor technology. Affordable and reliable sensors are making IoT technology possible for more manufacturers. • Connectivity. A host of network protocols for the internet has made it easy to connect sensors to the cloud and to other “things” for efficient data transfer. • Cloud computing platforms. The increase in the availability of cloud platforms enables both businesses and consumers to access the infrastructure they need to scale up without actually having to manage it all. • Machine learning and analytics. With advances in machine learning and analytics, along with access to varied and vast amounts of data stored in the cloud, businesses can gather insights faster and more easily. The emergence of these allied technologies continues to push the boundaries of IoT and the data produced by IoT also feeds these technologies. • Conversational artificial intelligence (AI). Advances in neural networks have brought natural-language processing (NLP) to IoT devices (such as digital personal assistants Alexa, Cortana, and Siri) and made them appealing, affordable, and viable for home use.
- 7. HOW IOTWORKS? • 1) Sensors/Devices • 2) Connectivity • 3) Data Processing • 4)User Interface
- 8. 1) SENSORS/DEVICES • Sensors or devices are a key component that helps you to collect live data from the surrounding environment. • All this data may have various levels of complexities. • It could be a simple temperature monitoring sensor, or it may be in the form of the video feed.
- 9. 2) CONNECTIVITY • All the collected data is sent to a cloud infrastructure. • The sensors should be connected to the cloud using various mediums of communications. • These communication mediums include mobile or satellite networks, Bluetooth,WI-FI, WAN, etc.
- 10. 3) DATA PROCESSING • Once that data is collected, and it gets to the cloud, the software performs processing on the gathered data. • This process can be just checking the temperature, reading on devices like AC or heaters. • However, it can sometimes also be very complex like identifying objects, using computer vision on video.
- 11. 4)USER INTERFACE • The information needs to be available to the end-user in some way which can be achieved by triggering alarms on their phones or sending them notification through email or text message. o The user sometimes might need an interface which actively checks their IoT system. • For example, the user has a camera installed in his home. He wants to access video recording and all the feeds with the help of a web server.
- 12. WHAT IS AN EXAMPLE OF AN INTERNET OF THINGS DEVICE? • A lightbulb that can be switched on using a smartphone app is an IoT device, as is a motion sensor or a smart thermostat in your office or a connected streetlight. • An IoT device could be as fluffy as a child's toy or as serious as a driverless truck. • Some larger objects may themselves be filled with many smaller IoT components, such as a jet engine that's now filled with thousands of sensors collecting and transmitting data back to make sure it is operating efficiently.
- 13. IOT BENEFITSTO ORGANIZATIONS • monitor their overall business processes; • improve the customer experience (CX); • save time and money; • enhance employee productivity; • integrate and adapt business models; • make better business decisions; and • generate more revenue.
- 14. WHY IS INTERNET OFTHINGS (IOT) SO IMPORTANT? • Over the past few years, IoT has become one of the most important technologies of the 21st century. • Now that we can connect everyday objects—kitchen appliances, cars, thermostats, baby monitors—to the internet via embedded devices, seamless communication is possible between people, processes, and things. • By means of low-cost computing, the cloud, big data, analytics, and mobile technologies, physical things can share and collect data with minimal human intervention.
- 15. IOT APPLICATIONS • Smart Thermostats • Connected Cars • Activity Trackers • Parking Sensors • Connect Health • Smart City
- 16. CHALLENGES OF INTERNET OFTHINGS (IOT) • Insufficient testing and updating • Concern regarding data security and privacy • Software complexity • Data volumes and interpretation • Integration with AI and automation • Devices require a constant power supply which is difficult • Interaction and short-range communication
- 17. ADVANTAGES OF IOT • Ability to access information from anywhere at any time on any device; • Improved communication between connected electronic devices; • Transferring data packets over a connected network saving time and money; and • Automating tasks helping to improve the quality of a business's services and reducing the need for human intervention.
- 18. DISADVANTAGES IOT • As the number of connected devices increases and more information is shared between devices, the potential that a hacker could steal confidential information also increases. • Enterprises may eventually have to deal with massive numbers -- maybe even millions -- of IoT devices, and collecting and managing the data from all those devices will be challenging. • If there's a bug in the system, it's likely that every connected device will become corrupted. • Since there's no international standard of compatibility for IoT, it's difficult for devices from different manufacturers to communicate with each other.
