Internet of Things

  1. 1. Internet Of Things By: Amr Samy Abd El-Aziz Embedded Mobile Systems track, ITI Ismailia 1
  2. 2. AGENDA • Introduction • IoT Today • Who Push towards IoT ? • Why Is IoT Important? • IoT as a Network of Networks • Building Blocks of IoT • IoT Challenges • Summary 2
  3. 3. “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 when more “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
  4. 4. 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”. 4

  6. 6. Who Push towards IoT ? 6
  7. 7. Why Is IoT Important? (Cont‟d) •We Evolve Because We Communicate 7
  8. 8. 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 8
  9. 9. IoT as a Network of Networks 9
  10. 10. Building Blocks of IoT 10
  11. 11. 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 11
  12. 12. 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
  13. 13. 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. 13
  14. 14. Communication(Cont‟d) Today‟s Wireless technology 14
  15. 15. IoT challenges • Definition • Radio Spectrum • Numbering and Addressing • Security and Privacy 15
  16. 16. 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
  17. 17. 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
  18. 18. •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
  19. 19. •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
  20. 20. Challenge: Global Standards Increasingly fragmented IoT standardization landscape 20
