Vision of IoT
 May have intends to detect physical wonders (e.g., temperature, light,
electromagnetic radiation level) or to trigger activities affecting the
physical reality (actuators).
 Possess a one of a kind identifier.
 Have a physical epitome and an arrangement of related physical
components (e.g., measure, shape, and so forth.).
 Have an insignificant arrangement of correspondence functionalities, for
example, the capacity to be found and to acknowledge approaching
messages and answer to them.
 Are related to no less than one name and one address. The name is an
intelligible portrayal of the question and can be utilized for thinking
purposes. The address is a machine-meaningful string that can be utilized
to convey to the question.
 Possess some fundamental registering abilities. This can go from the
capacity to coordinate an approaching message to a given impression (as in
uninvolved RFIDs) to the capacity of performing rather complex
calculations, including administration disclosure and system administration
assignments.

Introduction to IoT
 “Internet” is to provide a connection between computers worldwide.
 “Things” is referring to devices that are capable of communicating data
electronically over an Internet connection
 So what is the Internet of Things? For now you can think of IoT as a
system that uses the infrastructure of the Internet to establish a connection
to and between our electronic devices.

Introduction to IoT
 What Microsoft say about the Internet ofThings:
 "The Internet of Things (IoT) is not a futuristictrend;
 it’s the first step toward becoming a truly digital business and it starts
with your things
 your line-of-business assets and the data they produce, your cloud
services, and your business intelligence tools.
 That’s the Internet of Your Things, With an IoT strategy in place you
can make your business thrive."

•Internet of Things(IoT) is a network of physical
objects or people called "things" that are embedded with
software, electronics, network, and sensors that allows
these objects to collect and exchange data.
•The goal of IoT is to extend to internet connectivity
from standard devices like computer, mobile, tablet to
relatively dumb devices like a toaster.

Physical Design Of IOT
•Things in IOT
•IOT Protocols

IoT Protocols:
1) Link Layer :
Protocols determine how data is physically sent over the network‘s
physical layer or medium.
Local network connect to which host is attached. Hosts on the same
link exchange data packets over the link layer using link layer protocols.
Link layer determines how packets are coded and signaled by the
h/w device over the medium to which the host is attached.
•802.3-Ethernet:
•802.11-WiFi:
•802.16 - WiMax:
•802.15.4-LR-WPAN:
•2G/3G/4G- Mobile Communication:

Protocols:
(i)802.3-Ethernet: IEEE802.3 is collection of wired Ethernet standards for
the link layer. Eg: 802.3 uses co-axial cable; 802.3i uses copper twisted
pair connection; 802.3j uses fiber optic connection; 802.3ae uses
Ethernet overfiber.
(ii)802.11-WiFi: IEEE802.11 is a collection of wireless LAN(WLAN)

to250kb/s.
(v)2G/3G/4G- Mobile Communication: Data rates from 9.6kb/s(2G) to up
to100Mb/s(4G).

2) Network/Internet Layer:
Responsible for sending IP datagrams from source n/w to
destination n/w. Performs the host addressing and packet
routing. Datagrams contains source and destinationaddress.
Protocols:
IPv4: Internet Protocol version4 is used to identify the devices on a
n/w using a hierarchical addressing scheme. 32 bit address. Allows
total of 2**32addresses.

this layer protocols provide end-to-end message transfer
capability independent of the underlying network.
Protocols:
(i)TCP: Transmission Control Protocol used by web browsers(along with
HTTP and HTTPS), email(along with SMTP, FTP). Connection oriented and
stateless protocol. IP Protocol deals with sending packets, TCP ensures
reliable transmission of protocols in order. Avoids n/w congestion and
congestion collapse.
(ii)UDP: User Datagram Protocol is connectionless protocol. Useful in
time sensitive applications, very small data units to exchange. Transaction
oriented and stateless protocol. Does not provide guaranteed delivery.

4) Application Layer:
Application layer protocols define how the applications interface
with the lower layer protocols to send over the network.
Protocols:
(i) HTTP: Hypertext Transfer Protocol (HTTP) is an application-layer
protocol for transmitting hypermedia documents, such as HTML. It was
designed for communication between web browsers and web servers,
but it can also be used for other purposes. Follow request- response
model Stateless protocol.

(ii)CoAP: Constrained Application Protocol for machine-to-
machine(M2M) applications with constrained devices, constrained

2 Logical designof IoT: Communication Models

LOGICAL DESIGN of IOT
Logical design of IoT system refers to an abstract
representation of the entities & processes withoutgoing
into the low-level specifies of the implementation. For
understanding Logical Design of IoT, we describes given
below terms.
IoT Functional Blocks
IoT Communication Models
IoT Communication APIs

functional blocks are:
Device: An IoT system comprises of devices that provide
sensing, actuation, monitoring and controlfunctions.
Communication: Handles the communication for the IoT
system.
Services: services for device monitoring, device control service,
data publishing services and services for device discovery.
Management: this blocks provides various functions to govern
the IoT system.
Security: this block secures the IoT system and by providing
functions such as authentication , authorization, messageand
content integrity, and data security.
Application: This is an interface that the users can use to
control and monitor various aspects of the IoT system.
Application also allow users to view the system status andview
or analyze the processed data.

1. IoT Communication Models
• Request-Response Model
• Publish-Subscribe Model
• Push-Pull Model
• Exclusive Pair Model

•Request-response model is communication model in which the client
sends requests to the server and the server responds to the requests.
When the server receives a request, it decides how to respond, fetches
the data, retrieves resource representation, prepares the response, and
then sends the response to the client. Request-response is a stateless
communication model and each request-response pair is independent of
others.
•HTTP works as a request-response protocol between a client and server.
A web browser may be the client, and an application on a computer that
hosts a web site may be the server.
Example: A client (browser) submits an HTTP request to the server; then
the server returns a response to the client. The response contains status
information about the request and may also contain the requested
content.

•Publish-Subscribe is a communication model that
involves publishers, brokers and consumers. Publishers
are the source of data. Publishers send the data to the
topics which are managed by the broker.
•Publishers are not aware of the consumers. Consumers
subscribe to the topics which are managed by the broker.
When the broker receive data for a topic from the
publisher, it sends the data to all the subscribed
consumers.

•Push-Pull is a communication model in which the data
producers push the data to queues and the consumers
Pull the data from the Queues.
•Producers do not need to be aware of the consumers.
Queues help in decoupling the messaging between the
Producers and Consumers.
•Queues also act as a buffer which helps in situations
when there is a mismatch between the rate at which the
producers push data and the rate rate at which the
consumer pull data.

•Exclusive Pair is a bidirectional, fully duplex communication
model that uses a persistent connection between the client
and server. Connection is setup it remains open until the
client sends a request to close the connection.
•Client and server can send messages to each other after
connection setup. Exclusive pair is stateful communication
model and the server is aware of all the open connections.

2. IoT Communication APIs
Generally we used Two APIs For IoT Communication.:
•REST-based Communication APIs
•Web Socket-based Communication APIs

REST-based Communication APIs
•REST is a set of architectural principles by which you can design Web
services the Web APIs that focus on systems' resources and how
resource states are addressed and transferred.
•REST APIs that follow the request response communication model, the
rest architectural constraint apply to the components, connector and
data elements, within a distributed hypermedia system.
The rest architectural constraint are as follows:
•Client-server –
•Stateless
•Cache-able –
•Layered system –
•Uniform interface
•Code on demand

Client-server – The principle behind the client-server
constraint is the separation of concerns. for example clients
should not be concerned with the storage of data which is
concern of the serve. Similarly the server should not be
concerned about the user interface, which is concern of the
client.
Stateless – Each request from client to server must contain
all the information necessary to understand the request,
and cannot take advantage of any stored context on the
server. The session state is kept entirely on the client.

Cache-able – Cache constraints requires that the data within
a response to a request be implicitly or explicitly leveled as
cache-able or non cache-able.
Layered system – layered system constraints, constrains the
behavior of components such that each component cannot
see beyond the immediate layer with they are interacting.

Uniform interface – uniform interface constraints requiresthat
the method of communication between client and server must
be uniform. When a client holds a representation of resources
it has all the information required to update or delete the
resource you (provided the client has required permissions).
Code on demand – Servers can provide executable code or
scripts for clients to execute in their context. this constraintis
the only one that is optional.

WebSocket based communication API

•Websocket APIs allow bi-directional, full duplex communication between
clients and servers.
•Websocket communication begins with a connection setup request sent by
the client to the server. The request (called websocket handshake) is sent
over HTTP and the server interprets it is an upgrade request.
• If the server supports websocket protocol, the server responds to the
websocket handshake response.
• Websocket API reduce the network traffic and latency
•Websocket suitable for IoT applications that have low latency or high
throughput requirements. So Web socket is most suitable IoT
Communication APIs for IoT System.

is essential for recording changes in the environment.
Wireless sensor technology play a pivotal role in bridging the
gap between the physical and virtual worlds, and enabling
things to respond to changes in their physical environment.
Sensors collect data from their environment, generating
information and raising awareness about context.
Example: sensors in an electronic jacket can collect
information about changes in external temperature and the
parameters of the jacket can be adjusted accordingly

Sensors
 IoT sensors implanted in smart devices.
 sensors recognize changes in a particular amount (e.g., weight)
 Triggers the event or change information to the cloud (specifically or by
means of a gateway) and, in a few conditions, accepting information
back from the cloud (e.g., a control commands) or speaking with other
smart devices.
 Since 2012, sensors have for the most part contracted in physical size
and in this way have caused the IoT market to develop quickly.
 "Mechanical enhancements made infinitesimal scale sensors, prompting
the utilization of innovations like Microelectromechanical frameworks
(MEMS).

Edge Devices:

Integrated access device (IAD), multiplexer, or metropolitan zone
arrange (MAN) and wide zone organize (WAN), access device which gives
a entry point from the worldwide, open Internet into an ASP's or other
venture's private system.
 In Industry 4.0, these edge gadgets are getting to be plainly more
intelligent at handling information before such information even achieves
an endeavor system's network backbone (i.e., its center gadgets and
cloud server farms).

Embedded Systems:
 Embedded systems intended to play out a specific set of tasks.
 Key segments of an embedded framework incorporate chip or
microcontroller, memory (RAM,ROM,cache), organizing units(Ethernet, WiFi
connectors), input/yield units (show, console, and so on) and capacity, (for
example, streak memory).
 Some embedded systems have particular processors, for example, digital
signal processors (DSPs), graphic processors and application specific
processors.
 Embedded systems run embedded operating systems such as real time
operating systems(RTOS).

retransmission of lost packets.

Wireless Sensor Networks:
 A WSN contains distributed devices connected with sensors which
are utilized to observe and monitor the ecological and physical
conditions.
 A WSN comprise of various end-hubs and switches and a
coordinator.
 End hubs have a few sensors appended to them.
 End hubs can be also served as switches.
 Switches are in charge of routing the information bundles from
end-hubs to the coordinator.
 The coordinator gathers the information from every one of the
hubs. Coordinator can also act as a facilitator/gateway that
connects WSN to the web.
 A few cases of WSNs are Indoor air quality, Soil dampness ,
Weather check, Surveillance frameworks.

Wireless Sensor Network
•Distributed Devices with sensors used to monitorthe
environmental and physicalconditions
Or
•It is a network formed by large no. of sensor
nodes to detect light, heat , pressure ect.
i.e. used to monitor environmental and
physical conditions.
•Each node can have several sensors
attached to it.
• Each node can also acts as a routers
• Coordinator collects data from all nodes
• Coordinator acts as gateway that
connects WSN to the internet.

Examples of WSNs

Cool, but…
• Data quality of various sources
• Accuracy of each data point
• Sensor reliability and availability
• Time of measurement
• Important for trust!
• Unit jungle:
• nGy/s, mSv/h, Sv/h, Bq/kg, cpm …
• Sometimes misleading, sometimes just hard to compare…
• Mix of data sources
• Real sensors
• Virtual sensors (data scraping from web pages, e.g.,

M2M Scenario– IceCreamCabinets
• The application provides consumer products
companies with detailed information about
the location and status of its ice cream
cabinets.
• This information can be used to find these
cabinets, supply them with new ice cream
in time, and monitor their temperature in
order to avoid ice cream becoming bad due
to a defective ice cream cabinet.
• The ice cream cabinets become smart items
that monitor their energy consumption,
send alarms, and become an active part in
the companies operation processes as well
as sustainability efforts.
