Week 04 Flashcards
What are wireless sensor networks
Networks 1000s of interconnected wireless
devices embedded into the physical environment that are linked into an interconnected network that routes the
data to a computer for analysis. Used to monitor building security, detect
hazardous substances, monitor environmental
changes, traffic, or military activity. Require low-power, long-lasting batteries and
ability to endure in the field without maintenance
How does Wireless sensor network function hardware wise?
Number of devices can analyse whole areas. Made up of low levela nd high level nodes. Lower-level nodes
forward data to each
other or to higher-
level nodes, which
transmit data more
rapidly to a server and speed up
network
performance. The server that data from the sensors is sent to acts as a gateway to a network based on Internet technology
Give an example of some tech that is an important course of data for IOT
RFID is an important source of data for IOT.
How do we rely on IOT in daily lives
In our daily lives, we have become more reliant on IoT with our wearable tech, our
appliances, our cars, and how we receive health care.
How is wearable tech important for healthcare
Important o keep an eye on people, often in modern medicine we can cure things but only if spotted in time. Also data could be relevant in insurance on text - not really permitted though
What do the Internet engineering task force define the IOT as?
The basic idea is that IoT will connect objects
around us (electronic, electrical, non-electrical) to
provide seamless communication and contextual
services provided by them.”
“Development of RFID tags, sensors, actuators,
mobile phones make it possible to materialize IoT
which interact and co-operate each other to make
the service better and accessible anytime, from
anywhere
On what scale has the amount of global active IOT connections increased? What are the driver of this
More than 10 times (approx) since 2015. Things that originally were very specialised are now mass market. The increasing volume of data is not coming from devices that humans directly use. Instead, the increase in data is largely
coming from remote sensors without a human interface or a very limited human
interface.
Explain a smart thermostat and give an example
Smart thermostat, both “learns” your schedule and connects to a website over your home Wi-Fi.
This collects information about you and allows you connect to the thermostat remotely,
for instance to turn on the heat before you arrive.
Give examples of wearables connected to IOT
Activity tracker, smart glasses, smart watch, smart shoes, on body monitoring system, smart wristband
What are the drivers of IoT
Need for more information
Rapidly falling cost of – Sensors and other components
Emergence of better software so we can make sense of IoT data – Open Source Software (made by community)
Widespread network availability
AI info processing
Inexpensive cloud computing
Information is valuable and this is a rich source
What is the Value in IoT?
IOT sensors etc provide more information – better control, decisions
Manufacturing/logistics
– Control of process and can Identify problems
Home automation devices – Information collected on how people live and could link into Future “Smart” tariffs for electricity etc
What are some issues with IoT?
- IOT standards still evolving
- IOT devices have primitive security
– easily hacked - Remote storage of personal details ex: Amazon Echo Dot requires users to store their Wi- Fi network router passwords on an Amazon server.
- Collection of data about personal habits could be dangerous- ex: when you leave house
The collection of data always poses the issue of that data being misused as well as
offering the benefits of its proper use.
Where do actuaries see value in IoT devices?
Actuaries see the potential of IOT type devices as a source of additional data.
From point of view of an actuary and health insurer what Qs should be considered considering wearable tech data
What can be measured?
What data is captured, and by what process?
How accurate and reliable is that data?
How do users engage with the technology? - EX: skewed assessment if only fit people use smartbandsWhat is cost of using this technology?
Expected impact on behaviour, if any
