Internet of Things
Lecture 1
What is IoT?
• • A phenomenon which connects a variety of things – Everything
that has the ability to communicate
Connection of Multiple Visions
IoT Definitions
• The Internet of Things, also called The Internet of Objects, refers
to a wireless network between objects, usually the network will
be wireless and self-configuring, such as household appliances.
• The term "Internet of Things" has come to describe a number of
technologies and research disciplines that enable the Internet to
reach out into the real world of physical objects.
• “Things having identities and virtual personalities operating in
smart spaces using intelligent interfaces to connect and
communicate within social, environmental, and user contexts”.
Characteristics of IoT
• 1) Dynamic & Self Adapting:
• I o T d e v i c e s and syste m s m ay hav e the c ap ab i l i ty to
dynamically adapt with the changing contexts and take actions
based on their operating conditions, user‘s context or sensed
environment. Eg: the surveillance system is adapting itself
based on context and changing conditions.
• 2) Self Configuring:
• allowing a large number of devices to work together to provide
certain functionality.
• 3) Inter Operable Communication Protocols: support a number
of interoperable communication protocols and can
communicate with other devices and also with infrastructure.
• 4) Unique Identity: Each IoT device has a unique identity and a
unique identifier(IP address). 5) Integrated into Information
Network: that allow them to communicate and exchange data
with other devices and systems.
• The things should be:
• – Distinguishable and have unique identification
• – Able to detect the presence of other objects
• – Able to capture data autonomously.
• – Interoperable among various communication technologies
• – Have a secure and fail-safe operation
• – Operate at low power.
• – Programmable by the user
• – Contextual in nature.
• There would be more value added if the things
• – Have a service
• –based operation
• – Cooperate autonomously with others things.
Applications of IoT
1) Home
2) Cities
3) Environment
4) Energy
5) Retail
6) Logistics
7) Agriculture
8) Industry
9) Health & Lifestyle
Internet of Things
• It connects things beyond people
• – Can track and control many devices
• It is physical beyond information
• – Can directly impact physical aspects of our life
(comfort, health, safety, green, … )
•
• I t e m p o w e rs d e v i c e s to se nse a nd re a so n a b o ut t he
environment
• – Can be an assistant or agent for human beings, or
an autonomous decision maker
• All these mean new opportunities and challenges, in areas
such as devices, networking, systems, machine learning,
security and privacy
• IoT for enterprises
• – Smart meters (utility companies), smart vehicles (car
companies), intelligent healthcare (insurance companies), …
• IoT for consumers
• – Wearable's such as smart watches, smart bands, and
intelligent headsets
• – Smart homes which are open to various consumer IoT
appliances
• – Tons of new devices every year!
• IoT for consumers is where market explosion could happen in
the next 10 or 20 years
IoT Building Blocks
• Sensors
• – The front end or the things of the system § Processors
• – Process the data captured by the sensors and provide
intelligence
• – Real-time basis
• – Controlled by applications which are also responsible
for securing the data
• Gateways
– Route the processed data and send it to proper
locations for proper analysis and utilization.
• Applications
– Form another end of an IoT system
– Typically cloud-based
– Controlled by users
