3. o The Internet of things is the interworking of physical devices, vehicles
,buildings and other items embedded with electronics, software, sensors,
actuators, and network connectivity that enable these objects to collect and
exchange data.
o The IoT is Based On the M2M Connections between the various
devices, sensors, software etc.
o IoT allows objects to be sensed and controlled remotely across existing
network infrastructure, creating opportunities for more direct integration
between the physical world and computer-based systems, and resulting in
improved efficiency, accuracy and economic benefit.

4. o The 'Internet of Things' basically works by M2M (Machine to Machine)
communication, in which physical objects or 'Things' function by interacting with
each other. The user can assess, analyze and control the functioning of his 'Things'.
o It based on built-in hardware and software to send and receive data via various
communication protocols.
o The Internet of Things (IoT) consists of all the web-enabled devices that collect,
send and act on data they acquire from their surrounding environments using
embedded sensors, processors and communication hardware.

6. IoT Protocols
Most frequently used protocols for making Machine-to-Machine (M2M) communication in
IoT are:
1. MQTT (Message Queue Telemetry Transport)
o MQTT is a subscribes messaging transport protocol. The protocol runs over TCP/IP or over
other network protocol that provided ordered, lossless, bi-directional connections.
o It provides Features of one-to-many message distribution
o It also required less bandwidth and low power as compare to the http
IoT Working
7. 2. CoAP (Constraint Application Protocol)
• CoAP is a specialized web transfer protocol for use with constrained nodes and
constrained networks
• CoAP provides a request and response interaction model between application end
points
• CoAP is designed to friendly interface with HTTP for integration with the Web while
meeting specialized requirements such as multicast support, very low overhead and
simplicity for constrained environments
8. o Algorithms for IoT
The Algorithms used for computing of data in IoT are:
1. K-nearest neighbors algorithm
2. Case Based Reasoning
3. Naive Bayes
9. 1. K-nearest neighbors algorithm
• KNN is an non parametric lazy algorithm.
• K decides how many neighbors influence in the classification, this is usually an odd number

Type-1 7 7 Bad
Type-2 7 4 Bad
Type-3 3 4 Good
Type-4 1 4 Good
Task: For Type-5 Tissue, Find Class
for Acid durability(X) = 3
Strength(Y)=7 and K=3
Example:
10. Step1: Calculate Distance
Formula: D=squrt((X1-X)²+(X2-Y)²), Where, X=3 and Y=7
Name Acid durability

Type-4 1 4 3.6 2 Yes Good
Step3: Gather the Category Z of the nearest neighbor
Step4: Use simple majority of the category of the nearest neighbor
We have seen that there are two goods and one bad, the prediction is based on the. Therefore the type-5
tissue is belongs to Class-Good.

13. IOT IN AGRICULTURE
Applications of IoT
o IoT applications for smart agriculture: Smart Irrigation ,Green House
Control
o Smart irrigation system can improve crop yields while saving water.
• Smart irrigation systems use IoT devices with soil moisture
sensors to determined the amount of moisture on the soil and
release the flow of the water through the irrigation pipes only
when the moisture levels go below a predefined threshold.
• It also collect moisture level measurements on the server on in
the cloud where the collected data can be analyzed to plan
watering schedules.

Applications of IoT
o IoT applications for smart cities : Smart Parking ,Lighting for Road,
Smart Road, Structural Health Monitoring, Surveillance, Emergency
Response
o Smart Parking- Finding the parking space in the crowded city can be
time consuming and frustrating
• Smart parking makes the search for parking space easier and
convenient for driver.
• It can detect the number of empty parking slots and send the
information over the Internet to the smart parking applications
which can be accessed by the drivers using their smartphones,
tablets, and in car navigation systems.
• Sensors are used for each parking slot to detect whether the slot
is empty or not, and this information is aggregated by local
controller and then sent over the Internet to database.
