Internet of Things
The Internet of Things refers to a self configuring
wireless network between objects.
IT is expected to offer advanced connectivity of
devices, systems, and services that goes beyond
machine-to-machine communications (M2M) and
covers a variety of protocols, domains, and
IOT Enabling Technologies
To collect and process the data to detect the changes in the
physical status of things.
To enable the communication between the sensors and the
To enhance the power of the network by devolving
processing capabilities to different part of the network.
To make the smaller and smaller things to have the ability to
connect and interact.
The tagging of things may be achieved through such technologies:
• Radio Frequency Identification
• Near field communication
• QR codes
• Digital watermarking
¤ Near field communication (NFC) is the set of protocols that enables devices to
establish radio communication with each other by touching the devices together or
bringing them into proximity to a distance of typically 10 cm or less.
¤ A barcode is an optical machine-readable representation of data relating to the
object to which it is attached.
¤ A Quick Response Code (QR) code uses four standardized encoding modes (numeric,
alphanumeric, byte / binary, and kanji) to efficiently store data.
¤ A digital watermark is a kind of marker covertly embedded in a noise-tolerant signal
such as an audio, video or image data.
RFID(Radio Frequency Identification )Tags
¤ Wireless non- contact use of radio frequency electro-
magnetic fields to transfer data.
¤ Automatically identify and track tags attached to objects.
¤ Tags contain electronically stored information.
¤ Ability to monitor data.
Benefits of IOT
Tracking behavior for real-time applications.
Enhanced situational awareness.
Sensor-driven decision analytics.
Optimized resource consumption.
Instantaneous control in complex autonomous systems.
Challenges for IOT
¤ Technological Standardization in most areas still remain fragmented.
¤ Huge amount of Data ( Big Data).
¤ Managing and fostering rapid innovation is a challenge.
¤ Privacy and security.
¤ Testing of Multi-Discipline Systems.
¤ Absence of governance.
