3. What is Internet Of Things
The Internet of Things (IoT) is the network of
physical objects accessed through the Internet, as
defined by technology analysts and visionaries. These
objects contain embedded technology to interact with
internal states or the external environment.

4. Internet Of Things Contd..
In the future, digital sensing, communication, and
processing capabilities will be ubiquitously embedded
into everyday objects, turning them into the Internet of
Things (IoT). Smart devices will collect data, relay the
information or context to each other, and process the
information collaboratively.

5. Internet Of Things Contd..
An IoT system is a network of networks where,
typically, a massive number of
objects/things/sensors/devices are connected through
communications and information infrastructure to
provide value-added services via intelligent data
processing and management for different applications.

6. IoT Architecture

7. Internet Of Things Contd..
IoT enabling technologies such as sensors, radio frequency
identification, low power and energy harvesting, sensor
networks, machine-type communication, resource-constrained
networks, real-time systems, IoT data
analytics, in situ processing, and embedded software.

8. Smart Home Network
The smart home as using computer, network and
comprehensive wiring technology to integrate various
subsystems related to daily life into one system through
the household information management platform.

9. Technology for Smart Home
1. Wired Mode
All the control signals are transferred by wired mode and
the signal wires in controlling end are too many to check
when problems happened. This mode has lots of
prominent disadvantages such as complex cabling, high
workload, high-cost, difficult to maintenance and difficult
to build network.

10. Contd..
2.Wireless Mode
The wireless system applied to Smart home should have
the following characteristics:
1) low power consumption
2) Stabilization
3) easy to expand grid
As for the transmission speed, it is obvious not the key
point for this application.

11. Contd..
Here are several wireless modes for smart home as below:
Bluetooth:
Bluetooth is kind of wireless technology supporting
equipments short distances communication (in the range of
10 meters).While, this communication distance is too short
and this communication mode is the point-to-point, so this
kind of technology can’t meet the requirements for Smart
home.

12. Contd..
WIFI:
WIFI is kind of short distance transmission technology
which supports the radio signals within several hundreds
meters to connect with the Internet. The biggest feature of
WIFI is that it is very easy for people to access the Internet
at any time and any where.

13. Contd..
ZigBee / SmartRoom:
ZigBee / SmartRoom is based on the IEEE 802.15.
Because IEEE only deals with the protocol of MAC layer
and physical layer, ZigBee/SmartRoom Alliance expand
the IEEE and standardize the network layer protocol and
API.
ZigBee / SmartRoom is a new wireless network technique
with short range and low -power consumption, and it
mainly applies to short distance communication.

14. Smart Home Network Protocol
6LowPAN:
6LowPAN is a networking technology
that allows IPv6 packets to be carried efficiently
within small link layer frames such as those used by
IEEE 802.15.4.

15. 6LowPAN Overview
•It is desirable to use IP to communicate with small
devices.
–Widely deployed
– IPv6's addressing space is large, allowing even small
devices to have a real-world routable IPv6 address.

16. Architecture

17. Architecture contd..
LoWPANs are stub networks
•Simple LoWPAN
Single Edge Router
•Extended LoWPAN
Multiple Edge Routers with common backbone link
•Ad-hoc LoWPAN
No route outside the LoWPAN

18. Protocol Stack

19. 6LowPAN Implementation

20. Working
local or remote access from the Internet (via a secured
edge router)
monitor the home (temperature, humidity, activation of
remote video surveillance, status of the doors (locked or
open)
Home control (activate the air conditioning/ heating,
door locks, sprinklers, etc.).

21. Contd..
Optimize the level of energy consumption with input
from various sensors -light sensors, presence detection,
temperature, etc.
control electric window shades, chillers, air flow control,
air conditioning and heating
Smart Grid -interactions with the Grid for dynamic
monitoring or load shedding.

22. Applications
•Facility, Building and Home Automation
•Personal Sports & Entertainment
•Healthcare and Wellbeing
•Asset Management
•Advanced Metering Infrastructures
•Environmental Monitoring
•Security and Safety
•Industrial Automation
