Lecture 1 - Introduction

Question 1

What is the general definition of IOT?

Answer 1

Scenarios where network connectivity and computing capability extends to objects, sensors and everyday items not normally considered computers, allowing these devices to generate, exchange and consume data with minimal human intervention.

IoT is really all about data. We collect data, we analyse data, we act upon what the data tells us.

Question 2

What are some example components of IOT?

Answer 2

• IC, electronic chip– integrated circuit which can sense some physical event, which can compute to process that event in some way or fashion, and finally, which can communicate.
• Chip gets attached to the thing enabling this thing to become a piece of a bigger thing. Typically (but not always) the data that is collected from the thing is sent initially to a gateway. The gateway aggregates the data and sends the data to a Cloud, a computing Cloud.
• Data is going to create value from the things — Analysis, Feedback, Act

Question 3

In IOT connectivity must be/can be?

Answer 3

Billions of things —- These things must be networked. Therefore, one aspect of Internet of Things that really deals with massive networking connection of the devices must be in a fashion where the connectivity
* can be maintained,
* can be reliable,
* can be secure, and
* it doesn’t overwhelm computing resources, or bandwidth in the radio frequency domain.

Question 4

What are the 3 aspects of IOT?

Answer 4

1. We have things which can sense (provide some useful information about some physical phenomena) having some computing capability
2. Able to communicate - A mechanism or means of communicating to other devices or to a network should exist
3. Act - On the basis of analysis /insight gained from collected data something useful to happen

Question 5

What are some other names for IOT?

Answer 5

• Web of things,
• Internet of everything,
• Cloud or Fog network.

There are distinctions between them but to a great
degree they are very similar.

Question 6

What is the technical, social and economic significance?

Answer 6

The Internet of Things is an emerging topic of technical, social, and economic significance.
Consumer products, durable goods, cars and trucks, industrial and utility components, sensors, and other everyday objects are being combined with Internet connectivity and powerful data analytic capabilities that promise to transform the way we work, live, and play.

Question 7

Societal challanges for IOT?

Answer 7

Societal Challenges
* privacy fears
* surveillance concerns
* Security Concern (hacking of Internet-connected devices)

Question 8

Technical challanges for IOT?

Answer 8

Technical challenges
* Sensors
* Power Consumption
* Security & Privacy
* Data Analytics
* Communication Technologies
* Interoperability / Standards
* Development Challenges/ Enabling Technologies

Question 9

What is Enabling Technology challanges for IOT?

Answer 9

Enabling Technologies: The concept of combining computers, sensors, and networks to monitor and control devices has existed for decades.
* The recent confluence of several technology market trends, however, is bringing the Internet of Things closer to widespread reality.
* These include Ubiquitous Connectivity, Widespread Adoption of IP-based Networking, Computing Economics, Miniaturization, Advances in Data Analytics, and the Rise of Cloud Computing.

Question 10

Legal challanges for IOT?

Answer 10

Legal Challenges
The use of IoT devices raises many new regulatory and legal questions:
* Issues related to cross border data flows
* Data collected by IoT devices is sometimes susceptible to misuse, potentially causing discriminatory outcomes for some users.
