• Modified OSI Model for the IoT/M2M

Systems

Internet of things: Overview

• (^) Concept that enables communication between internetworking devices and applications
• (^) Concept begun with things classified as identity communication devices like RFID.
• (^) Definition: Internet : A vast global network of connected servers, computers tablets and mobiles that is governed by standard protocols. Things: any object

Polled questions

• (^) Define IOT

IOT Vision:

• (^) Things become smart and function like living entities by sensing, communicating, computing.

IoT conceptual framework:

• (^) Physical object+ controller, sensor & actuators+ internet= Internet of Things

Technology behind IoT:

Sensors & Control Units:

• (^) Electronic devices that sense physical environment.
• (^) Used for measuring temperature, pressure, humidity, light intensity, traffic proximity,etc.
• Two types:
  1. Analog output sensor: Analog inputs to the control unit. Ex- thermistor, photoconductor, pressure gauge, etc.
  2. Digital output sensors: Digital inputs to the control unit. Ex- touch sensor, metal sensor, traffic pressure sensors, etc.
• (^) Control Unit:
