In this presentation, Saloni introduces IoT and associated trends. Saloni's interest areas lie in security and Data Management of IoT applications.

2. Internet of Things(IoT) is a vision according to which all the physical
objects in this world will be connected to the internet. These objects will
constitute the “things” in the term IoT.
The bigger question is HOW?
According to Dr. John Barret, it involves 3 major steps:
1. Each “thing” needs to have a unique identity so that it can be
located/monitored/controlled/utilised across the world.
2. Every object should be rendered with the ability to communicate.
3. Senses need to be provided to all the things through sensors.
Take the example of a book Z. A person X wants to find out if somebody
is reading Z and if yes who is it?
1) Both Z and X need to have unique identifiers.
2) In order to let X know about Z, Z needs to communicate this
information. It can make use use of bluetooth modules.
3) To find out who is reading Z, it needs to have sensors. It may be in
the form of RFID.

3. •Smart Cities: Cities in the US like San Jose(CA) keep track of
traffic/congestion and weather conditions by collecting and analyzing data.
They have partnered with Intel to use its “Smart City Sensors” to do this job.
These sensors provide real time feedback and enable the smart cities to
utilise the resources judiciously. San Jose has even reduced its
dependency on fossil fuels.
•Truck companies: Truck companies use sensors and store data in data
centers wirelessly. Through proper analysis, they have been able to drive
more efficiently and save fuel. This helps them save around $15 million per
year.
•E-health: We already have apps that monitor a person’s heart’s
functioning, pulse rate etc. Soon this data shall be monitored by hospitals in
real time and in case of any anomaly, they will send an ambulance to the
patient’s location.

4. •Security: Undoubtedly, IoT will make this world a Panopticon. This means
that we will all be under constant surveillance implying that our privacy shall
be hacked.
What can be done? Limited/controlled access. But it’s implementation is
complex as certain organisations need to be provided with complete
access. Example, a hospital that monitors your heart’s functioning.
•Data Management: With increase in number of objects, the amount of
data stored and processed will increase exponentially.
What can be done? Data need to be stored efficiently without any scope
for redundancy or wastage. Also, data need to be updated after a stipulated
interval of time.
•Assignment of unique address: IPV6 provides us with only a limited
number of addresses but the number of things are going to be extremely
large.
What can be done? Algorithm that rotates limited number of addresses
among all “things”. Similar to dynamic IP addresses.
