The importance of sensor networks in our everyday
lives cannot be overstated. We depend daily on sensor networks
to monitor the safety of our bridges, buildings, tunnels and dams,
as well as to monitor the weather and provide alerts for dangerous
conditions. When the data provided by a sensor network is combined
with real-time transmission, powerful processing, and statistical
analysis techniques, an operator is armed with the tools to accurately
determine how a given system is working overtime and rapidly respond
to any issue that arise.
Benefits of Sensor Networks:
Early Warning Alert/Public Safety:
System parameters can be set, monitored
and users notified
Increases public safety by monitoring health
of machines and structures
Specialized sensor networks (often with
mobile sensor capability) can be deployed in remote areas,
with rough and/or hostile terrain, that may otherwise be difficult
or impossible to reach.
Precision Machine Operations:
Precise control of industrial equipment
can be maintained. For example: sensor networks can trigger
misting systems, open vents, turn on fans and control a wide
variety of system responses.
Reduce waste by precisely monitoring resource
use (water, electrical, etc) wirelessly transmitted back to
a central control center for billing.
Power station monitoring
Due to technological developments in the areas
of energy harvesting, MEMS and embedded software, the areas of
application for SNs has rapidly expanded. Sensor networks
can be used to create a variety of Smart Environments
whereby an end user can view real-time data and program the network
to respond automatically if conditions fall outside a given range.
For example, in response to humidity, temperature and CO2 levels,
vents in a greenhouse can be opened or closed and sprinkler system
outputs can be adjusted.
Patient bio measurements, vital signs
Wearable Mobile Sensors
The development of wearable wireless sensors
allows for applications in the area of health and e-sensors
Power Transmission Line
Electric Power Generators
Hazardous Chemical Levels, Disaster Area
Vehicular Ad-Hoc Network
VANET is a mobile network
of moving vehicles where each vehicle acts as a wireless router,
and/or sensor node. This allows vehicles within a few hundred
meters of one another to communicate, drop in and out of the network,
and create a wide ranging sensor network.
Police, fire, other civil sectors, as well
as a variety of industry sectors, can make use of this type
of mobile technology for increasing safety, communication and
creating innovative methods to serve customers.
