“The Internet of Things (IoT)refers to uniquely identifiable objects(things) and their virtual representations in an Internet-like structure”-Wikipedia

OR

“The Internet of Things (IoT )is simply the point in time whenmore “things or objects” were connected to the Internet than people.” – Cisco Internet Business Solutions Group (IBSG)

OR

“The Internet of Things (IoT) provides the foundational infrastructure for a smarter planet, and offers significant growth opportunities in IT, infrastructures and services” – IBM

Introduction 3

Introduction(Cont’d)

• First application was a Coke machine ,Carnegie Melon University, in the early of 1980s.

• First Named by Kevin Ashton (Auto-ID center at MIT ) in 1999 ”If We Had Computers that Knew Everything .. Using Data They Gathered Without Any help From us, we Would Be Able To Track

And count everything, And greatly Reduce waste, Loss And cost”.

Who Push towards IoT ? 6

Why Is IoT Important? (Cont’d)

• We Evolve Because We Communicate

Why Is IoT Important? (Cont’d)

IoT is critical for human beings

• As the planet’s population continues to increase, it becomes even more important for people to become stewards of the earth and its resources.

• people desire to live healthy, fulfilling, and comfortable lives for themselves, their families, and those they care bout

Building Blocks of IoT 10

Page 11: Internet of Things

Sensing Nodes

All types of sensing nodes needed for the IoT vary widely, depending on the applications involved :

• Sensing nodes could include a camera system for image monitoring

• Water or gas flow meters for smart energy• Radar vision when active safety is needed• RFID readers sensing the presence of an object or person• Doors and locks with open/close circuits that indicate a building

intrusion;• A simple thermometer measuring temperature

Layers of Local Embedded Processing Nodes

• Embedded processing is at the heart of the IoT. Local processing capability is most often provided by MCUs, hybrid microcontrollers/microprocessors (MCUs/MPUs) or integrated MCU devices, which can provide the “real-time” embedded processing that is a key requirement of most IoT applications.

12

Page 13: Internet of Things

Communication

• The role of the communication node is to transfer information gathered by the sensing nodes and processed by local embedded processing nodes to the destinations identified by the local embedded processing nodes. And, once the data is remotely processed and new commands are generated, the communication node brings back the new commands to the local embedded processing nodes to execute a task.

IoT challenges

• Definition

• Radio Spectrum

• Numbering and Addressing

• Security and Privacy

15

Page 16: Internet of Things

ITU Report in 2005: • IoT adds a new

dimension to the ICT world (“4A Vision”) - from ‘traditional’ anytime, any place connectivity for anyone, the Internet of Things brings connectivity for anything

Definition 16

Page 17: Internet of Things

Radio Spectrum

• Radio-frequency spectrum: a scarce natural resource, increasingly in demand from a large and growing number of services

• Can the RF spectrum handle 50 billion connected devices?*

* GSMA estimate for 2025. The World Wireless Research Forum estimates “7 trillion wireless devices serving 7 billion people by 2017”

17

Page 18: Internet of Things

• How to address 50 billion objects?

• Different technical solutions proposed: Electronic Product Codes

(RFID tags) ‘Traditional’ Uniform

Resource Identifiers (URI) IPv6: address space

supports 2128 addresses

• Issues beyond technology: Standards for numbering

and addressing schemes (ITU-T)

Harmonization, policies, regulation

All countries should be involved in the development and benefit from the IoT

Numbering and Addressing 18

Page 19: Internet of Things

• IoT may also connect transportation, electricity grids and other critical infrastructure Security risks and concerns

• Users are concerned about privacy and socio-ethical implications of the use of tracking and geo-location

Security and Privacy 19

Challenge: Global Standards

Increasingly fragmented IoT standardization landscape
