IoT, Big data with R. This slide is for a seminar

1. IoT - Big Data
2014.9 - Seonghak Hong (Data Scientist)
Ruser group in Korea

2. What is the IoT
• IoT = Internet of
Things. Really?
• It means "all things can
communicate via
Internet"
• It means "all things have
communication module
(Wifi, Bluetooth)"

3. What is the Big Data
We already know
• Big Data = Big + Data +
Distributed Computing
+ Analysis
• Input of Big Data =
Various and Massive
Data
• Output of Big Data =
Insights (also called
"Value")

4. Why IoT need Big Data (1)
• Things = Devices (Rasberry Pi, Arduino, ...)
with various sensor
• Devices grep a lot of data from sensors
• Temperature, Air Quality, Movements,
GPS, Pressure, Images, ...
• Devices have to store the data somewhere
else

5. Why IoT need Big Data (2)
• IoT data also have to be analyzed
• Massive data analysis are needed for getting
insights
• Realtime analysis is also needed for
instantaneous
• Big data do it

6. Problems of IoT device
• Electric power
• Battery? Adaptor?
• Low energy technology is solution
• Communication channel
• How can communicate without wire?
• Wifi and Bluetooth are solutions

• Smart home care
• Smart building care
• Smart health care
• Smart retail shop care
• and so on
