THE INTERNET OF THINGS (
I
O
T
)


I
ncorporates
physical objects into
the global
network of data, which
can be
accessed from almost anywhere in the world

ƒ
Adapting the
IoT

to smartphones could be very beneficial to users



Mostly
manual
data
input

Mostly
automatic
data input

Contains
objects with
IP address

Contains
objects
paired with
virtual
product
information

Interacts with
physical
environment

With
IoT



Without
IoT







TECHNOLOGY:
SYSTEM


Smartphone:

ƒ
Mobile phone built on a mobile
operating system


Relatively advanced computing
capabilities


Internet enabled


Objects:


Examples:


Heart rate monitor


Lights


Doors


Car


Thermostat


Have their own identification


Hub


Sits between
the objects and the
phone


Allows for interaction when not in the
near proximity of objects


Gives graphical representations
of the
IoT’s

current state


Allows for monitoring of data


Allows for sending of
commands


Stores data or sends data to the
cloud

Smartphone


Comprises of multiple
components


Each object has its own
identification using tags


Sensors and motors can be
attached to accomplish different
tasks


Flexibility allows the types of
objects to be nearly limitless

Objects


Allows for modularly expanding
a local
IoT


Stores data or sends data to the
cloud


Allows for remote viewing and
controlling of the
IoT

Hub

Data Transfer: Over the
Internet (Such as
Wifi

and
Cellular Service)

Data Transfer: Short
-
range
Communications, (Such as
RFID and
WiFi
)

Data Transfer: Short
-
range
Communications (Such as
RFID,NFC, and
WiFi
)

TECHNOLOGY
:
SENSORS


Cameras:

ƒ
P
rovide
frames from video or images of the surroundings that may then be
processed


May be used to get information for:


Light levels


Facial tracking


Edge detection


Motion Detectors:

ƒ
S
ense
motion by using ultrasound, passive infrared, microwave, or tomographic
methods


May
be used to get information
on things entering
or leaving a
room


Accelerometers:


D
etect orientation and acceleration


May
be used to get information for
:


D
etecting
the movement of certain parts of a
machine


Impact on objects

TECHNOLOGY:
LOCATION


Global Positioning System (GPS
):

ƒ
U
ses
an array of satellites to give a fairly accurate location of an
object


Better results outdoor


Indoor Positioning System
-

Infrastructure/Mobile (IPS
-
I/M
):


Functions by:

I.
Intermittently sending an ultrasound signal and a radio frequency signal to
an object

II.
Measures difference in return time for signals

III.
Algorithm uses multiple sources of distance data to determine location

TECHNOLOGY
:
SHORT
-
RANGE
COMMUNICATIONS


Radio Frequency Identification System (RFID):

ƒ
An
automatic technology that is used to identify objects, record metadata or
control individual targets through radio waves


Functional range: ~1 meter


Two types:


Active:
require a power
source


Passive: do not require a power source


Near
Field Communication (NFC):

ƒ
Require touching of smartphone in order to complete a transaction of data


Functional range: ~10 centimeters


Technology becoming more common in mobile devices


The
mobile phone will get the identification of the object from the NFC tag, and
then complete actions according to the object that the phone was tapped against


TECHNOLOGY:
THE HANDLING AND PRESENTATION OF DATA


Smartphones allow for graphical user interfaces

ƒ
Mix of simplicity and functionality is ideal


Application should serve as:

ƒ
A Control Center


Send commands to objects in the
IoT


An Alert System


Alert using notification system on mobile phones


A Data Viewer


Display appropriate graphs for the data collected


Store the data locally and on the cloud

TECHNOLOGY:
AMBIENT INTELLIGENCE


Key properties of ambient intelligence

ƒ
Seamless integration


Free and easily accessible


Relies on interconnectivity


Designed for humans


MIT Project Oxygen

ƒ
A project designed to make ambient intelligence possible


Ambient intelligence should be the ultimate goal of a mobile
-
centric
IoT

STANDARDIZATION

Example:
SmartThings

platform


Allows developers
to
easily program and build
objects and mobile phone
apps

ƒ
SmartThings

provides development kits and guidelines

ƒ
SmartApps

are applications that fit into one larger
SmartThings

application

ƒ
Caters
to
developers

BENEFITS:
EVERYDAY LIFE


Remotely control objects

ƒ
Adds user convenience


Possible benefits:


Heat car from a distance


Coffee ready when the user is


Driving improvements

ƒ
Parking spaces with
W
aspmote


Security Benefits

ƒ
Lock house or car door from anywhere


Notify users in emergency scenario

BENEFITS:
HEALTH AND ASSISTED LIVING


Keep in Touch (KIT):

ƒ
Collects and forwards important health data


Eliminates data input


Useful for:


P
atients who rely on regular medication


Alzheimer's patients


Closed loop principle:


Patients and doctors can access information


Allows doctors to easily alter treatment


Saving lives:

ƒ
Sensors can detect distress and alert authorities


BENEFITS:
BUSINESS AND EFFICIENCY


Monitor energy in an industrial setting:

ƒ
Intel’s system


Tracking products:

ƒ
Proper shipping conditions


Determining location


Maximizing efficiency:

ƒ
Adaptive machinery


Alerting employees

BENEFITS:
A CLEANER PLANET


Controlling heating:

ƒ
Tado

controller


Smart heat adjustments


Monitoring efficiency:

Transportation:

ƒ
Adaptable GPS systems in smartphones


Trucking fleets


Fuel consumption


Part replacement


BENEFITS:
AGRICULTURE


Tracking livestock:

ƒ
Sparked sensors


Notifies farmers:


Overall health


Pregnancy


Online livestock network

CONS:
SOCIAL ACCEPTANCE


Society must accept personal information being stored digitally

ƒ
Habits recorded may be used by employers to gauge potential employees

ƒ
Health records may prevent the unhealthy from getting affordable health
insurance

ƒ
Encryption and ensuring data remains private is necessary

ƒ
However:

ƒ
Companies see the potential for the
IoT’s

success in the market


Featured in the Consumer Electronics Show 2013


CONS:
SAFETY


Ability for outsiders to control your objects if
IoT

security is breached

ƒ
Harm can be done remotely once breached:

ƒ
Cars can be turned on and cause
c
arbon monoxide poisoning


Heating elements may be turned and cause fires


Preventing this:


Have the hub be manually paired with smartphones to only allow commands
from that device


Ensure good encryption for the hub and smartphone

CRYPTOGRAPHY


Allows for securing
of communication from unwanted
entities

ƒ
Limited resources limit the strength of the security

ƒ
If done correctly Cons of the
IoT

will be reduced greatly

ƒ
People will accept it more readily with safety in mind


Fewer breaches of security


General idea:

ƒ
Plaintext is converted to cipher text


Using: transposition, substitution, or a combination of the two


Only the rightful viewers may know the key that is used to cipher the text


Keys are then used to decipher the transformed message back to plaintext


Key management


Ensures keys remain unknown to outsiders


Allows keys to be shared and agreed upon with intended sender and receiver

Encryption


Technical points of the
IoT


System of objects, smartphones, and hubs

RFID and NFC provide communication and identification


Potential
difficulties:


Data could be insecure


Lack of interest


Too expensive
