A sensor generates data, but that data will only be useful if it is
interpreted properly. Each IoT device has a unique identity. This
Unit - 1 identification is helpful in tracking the equipment and at times for
querying its status.
Introduction - 3. Scalability
According to the definition of IoT, It is the way to interconnect with the Scalability means the amount of data one can handle efficiently. The IoT
help of internet devices that can be embedded to implement the has created a setup to handle huge amount of data and generate useful
functionality in everyday objects by enabling them to send and receive analysis.
data. IoT development involves a wide range of technologies, including
wireless communication protocols, cloud computing, big data analytics,
machine learning, and security technologies. 4. Dynamic and Self-Adapting
IoT devices should dynamically adapt themselves to changing contexts
Some examples of IoT devices include:
and scenarios. Assume a camera meant for surveillance. It should be
• Wearables such as fitness trackers and smartwatches.
adaptable to work in different conditions and different light situations
• Smart home devices such as thermostats, lighting systems, and
(morning, afternoon, and night).
security systems.
• Healthcare devices such as patient monitoring systems.
As IoT devices and systems become increasingly widespread, the 5. Architecture
opportunities for innovation and growth in this field will continue to The architecture of IoT is designed in a way that it is capable of
expand. supporting various devices, technologies, and protocols. Its main work
is to confirm whether each connected device does not interfere with the
other. This way, the safety and security of each device's data are
maintained.

6. Self-Configuring
This is one of the most important characteristics of IoT. IoT devices are
able to upgrade their software in accordance with requirements with a
minimum of user participation. Additionally, they can set up the network,
allowing for the addition of new devices.
1. Connectivity
Connectivity is an important requirement of the IoT infrastructure.
Things of IoT should be connected to the IoT infrastructure. Anyone, 7. Security
anywhere, anytime can connect, this should be guaranteed at all times. With the increasing number of IoT devices, issues regarding the security

is a chance of personal data being transferred without approval, which
is a matter of concern. To overcome this challenge, IoT has created

Maintaining safety and security is a big dare for IoT. However, it still
handles it without any disruption.
