2. What is IOT ?
The Internet of things (IoT) is the network of physical Objects
devices, vehicles, home appliances, and other items embedded
with electronics, software, sensors, actuators, and connectivity which
enables these things to connect, collect and exchange data

10. IOT Main Components

11. 1- Sensors & Actuators
Sensor: is a device that detects and
responds to some type of input from the
physical environment. The specific input
could be light, heat, motion, moisture,
pressure, or any one of a great number
of other environmental phenomena.
Aactuator : is a component of a
machine that is responsible for moving
and controlling a mechanism or system,
for example by opening a valve

23. Device-to-Device Communications
• The device-to-device
communication model represents
two or more devices that directly
connect and communicate between
each other, rather than passing
through an intermediary application
server.
• These devices can communicate
over various types of networks,
including IP networks or the
Internet. They usually make use of
protocols like Z-Wave or Bluetooth
to establish a direct device-to-
device communications.

24. Device-to-Cloud Communications
• Device-to-cloud communication involves
an IoT device connecting directly to an
Internet cloud service. It often uses
traditional wired Ethernet or Wi-Fi
connections, but can also use cellular
technology. Cloud connectivity allows the
user and an application to obtain remote
access to a device. It may also supports
pushing software updates to the device.
• From a security perspective, this model is
more complex than Device-to-Device since
it involves two different types of
credentials: the network access credentials
(such as the mobile device’s SIM card) and
the cloud access credential.

25. Device-to-Cloud Communications
• In Device-to-Gateway model, the IoT
devices connect to an intermediary device
to access a cloud service (Telphone) like
sport fitness tracker to phone then to
cloude. This model usually involves
application software operating on a local
gateway device (like a smartphone) that
acts as an intermediary between an IoT
device and a cloud service.
• This gateway could provide functionalities
such as security and data translation. If the
application-layer gateway is a smartphone,
the application software might take the
form of an application that pairs with the
IoT device and communicates with a cloud
service. This model can be seen in fitness
tracking devices such as the Nike+.

26. Back-End Data-Sharing Model
• Back-End Data-Sharing essentially
extends the single device-to-cloud
communication model so that IoT
devices and sensor data can be
accessed by authorized third parties
and share the information.
• This model allows users to export
and analyze smart object data from
a cloud service in combination with
data from other sources, and send it
to other services for aggregation
and analysis.

37. PIH and UCN Concept
PIH : Personal Information Hub
UCN: User Centric Network
UCN relies on a distributed Personal
Information Hub (PIH) that contains
information such as the user context, her
mood, historical data about her taste,
expectation, social acquaintances, and her
network/device resources.
UCN will use these data to decide at any
point in time where to search content and
where to deliver it from, and how to
configure the delivery for a user in her
context. In addition, UCN creates
opportunities for a new range of
personalized services, based on geo-
location or fusion of very different sensor
data for example.

45. Sensors in even the holy cow!
In the world of IoT, even the cows will be connected and
monitored. Sensors are implanted in the ears of cattle. This
allows farmers to monitor cows’ health and track their
movements, ensuring a healthier, more plentiful supply of milk
and meat for people to consume. On average, each cow
generates about 200 MB of information per year. 45

58. NB-IOT
Narrowband Internet Of Things

59. What is NB-IOT? …
It is;
• Low Power Wide Area Network (LPWAN)
• Radio technology standard by 3GPP(3rd
Generation Partnership Project)
• Enables a wide range of devices and
services to be connected using cellular
telecommunications bands.

60. What is LPWAN?
• Fills the gap between mobile (3G, LTE) and short-range
wireless (Bluetooth, WiFi and ZigBee) networks.

61. Advantages is NB-IOT? …
• Very low power consumption
• Excellent extended range in buildings and underground
• Easy deployment into existing cellular network
architecture
• Network security & reliability
• Lower component cost

62. How NB-IOT works?
• Selected narrow bands on existing LTE base stations
• The NB-IOT can be deployed as a part of band, occupy the whole band or use
the guard band
• NB-IoT devices are authenticated in the same way as traditional cellular phones
and then can exchange the information with a network.

63. How NB-IOT works? …
Can use IPv4, IPv6 or non-IP data delivery (without IP
stack on the end node)
• In case of IP;
The device can be considered as Internet-connected device and can exchange the
data directly with application servers.
• In case of Non-IP;
A special elements inside a service provider network called SCEF or P-GW. IP stack is
added by these elements.

64. NB-IOT Security?
NB-IoT provides same transport layer security as a
cellular network and devices are authenticated with
standard SIM cards.
• Support for user identity confidentiality
• Entity authentication
• Confidentiality
• Data integrity
• Mobile equipment identification.

65. Consolidated Advantages of NB-IOT?
• Reduce cost (in terms of device as well as deployment).
• Power consumption(10 years battery life).
• Increased coverage.
• Deep penetration through hard surfaces, remote and
rural areas, underground locations, and deep inside
buildings
• Number of devices that can be connected.
• Power spectrum density (PSD) boosting and repetition
in NB-IoT can deliver coverage gains of 20dB when
compared with GSM networks, enabling about ten times
better area coverage.
