Fundamentals of IoT

This is an introductory course to internet of things where students will understand the fundamentals of the course as well as the protocols and devices in IoT. We will also understand the use of packet tracer and the devices and kind of cables used to set up IoT connections as well as protocols. At the end of the packet tracer course there is a practice lab to help you get the basic idea of setting up a work environment in IoT. So in a nutshell, IoT is a concept that connects all the devices to the internet and let them communicate with each other over the internet. IoT is a giant network of connected devices - all of which gather and share data about how they are used and the environments in which they are operated.

Kevin Ashton is an innovator and consumer sensor expert who coined and phrase "the internet of things" to describe the network connecting objects in the physical world to the internet.

“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 and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.”

How Does This Impact You?

The new rule for the future is going to be, "Anything that can be connected, will be connected." But why on earth would you want so many connected devices talking to each other? There are many examples for what this might look like or what the potential value might be. Say for example you are on your way to a meeting; your car could have access to your calendar and already know the best route to take. If the traffic is heavy your car might send a text to the other party notifying them that you will be late. What if your alarm clock wakes up you at 6 a.m. and then notifies your coffee maker to start brewing coffee for you? What if your office equipment knew when it was running low on supplies and automatically re-ordered more? What if the wearable device you used in the workplace could tell you when and where you were most active and productive and shared that information with other devices that you used while working?

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. These devices range from ordinary household objects to sophisticated industrial tools. With more than 7 billion connected IoT devices today, experts are expecting this number to grow to 10 billion by 2020 and 22 billion by 2025

Enterprises and service providers have been looking at IoT as a key enabler to drive digital transformation and to unlock the operational efficiencies. Advances in Artificial Intelligence coupled with ubiquitous connectivity, and real-time communication are enabling exponential growth in efficiencies generated by IoT. As machines and products have started communicating with each other without any human intervention, the real value of data is getting generated through better and faster decision-making, predictive analytics and automation.India is already matching the pace in adapting new technologies like IoT, 5G, AI and cloud to drive new business models. The Government of India has introduced various policies and initiatives to leverage benefits of these disruptive technologies in various sectors. Many start-ups in India are also using these technologies to create new and innovative business models. Through this paper, we have attempted to outline the future of IoT, from business potential and technology point of view, and its impact along with other emerging technologies such as 5G, Artificial Intelligence, Digital Twin, Edge Computing, Immersive User Experience, etc. on various sectors such as manufacturing, utilities, transport and logistics, agriculture, oil and gas and smart cities. We are glad to be the knowledge partners with FICCI for the first edition of IoT Summit on “Transforming businesses through technology disruption” in Rajasthan. This is an exclusive platform for stakeholders from the government and industries to collaborate on the adoption of these disruptive technologies

Physical separation helps to divide physically the network in several sub-areas introducing a more realistic aspect of it such as a need of backbone connections,a physical wiring length limitation and WLAN coverage limitations and a need of custom environmental variables.Every physical sub-layer, except for the wiring cabinets, are coming with a large set of fully customized environmental variables,.Variables are t unable parameters for representing real life environments such as: amount of sunlight, air carbon dioxide-concentration, gravity, winds speed and many more. In Cisco Packet Tracer there are more than fifty different variables that students can adjust accordingly based on a 24 hours time range.In the Figure 10 below one can see the amount of sunlight and rain setup in the Smart-campus exercise. Variables are necessary in order to influence the sensor behavior in the IoT simulations. Variables are in fact detected by the sensor and, as a consequence,actions are then triggered. Adjusting variables was also helping students in order to validate immediately if the IoT logic setup was done correctly.

Example of  environmental variable set up In the provided four simulations the variables utilized were: sunlight and wind speed level,in order to boost electricity production done by solar panel and wind turbine. Also amount of raining manipulations were used during a random time of the day in order to activate the water sensors, sensors were then placed in the school sport field, to detect extra water level and stop the water irrigation sprinklers.In the Smart-Home cases also humidity and temperature levels variable were changed in order to fire up the home AC unit. Creation of a smaller sub-container helped also to boost the environmental changes in the variable parameter.As an example, if an old car was placed in the city level and it was turned on, the level of carbon dioxide build up in the city level would have raised at a slower pace compared if the car was turned on in a sub-container. In the second case, being in a smaller space, like a car garage, the carbon dioxide sensor picked up carbon dioxide variation faster than in the city level.
