WSN Scope
Over the last decade, wireless sensor networks
(WSNs) have attracted a lot of attention from the
research community.
 With hundreds or thousands of sensor nodes, a
WSN must employ distributed algorithms to
support its applications.
WSN Scope
 These algorithms must be highly localized as
long distance transmissions are very expensive,
and would diminish the network's overall
lifespan.
WSN must be self-configurable, highly scalable,
redundant, and robust.
WSN Scope
The features of WSNs can be applied to a
variety of applications for environmental for
example :




(agriculture, water, forest) monitoring.
battle field surveillance.
health (e.g., elderly people) monitoring.
and industry process control.
WSN Scope
In the near future. For instance, disaster relief
applications can provide an effective system to
detect living human beings to help successfully
manage a disaster relief operation, potentially
saving hundreds of lives.
Wireless Solutions
Wireless Solutions
A WSN is a collection of nodes with




low performance CPU,
memory,
radio transmitter
and sensors .
They make environmental measurements
(sensing) and transmit them to a collection point,
which then forwards them to a remote
processing system.
Wireless Solutions
The characteristic of these nodes is that they are




small,
low-power,
wirelessly interconnected
and cost-effective.
The network form has the characteristic of being
self-configuring and autonomous, requiring no
human intervention, can cover a very large area
and can remain active for a long time.
Wireless Solutions
Solutions based on WSN saves
 a lot on costs,
 monitor much larger areas with extreme
environmental conditions and in places very narrow
and difficult to reach.
Moreover, given the low cost of each node are used in
emergency situations where they may be destroyed
or lost in some way, such as in areas at risk of fire or
landslides.

Precision Agriculture
 Vineyards and Greenhouses
 In this context, the sensors network is used to monitor
environmental parameters of crop cultivation, so that
the farmer knows, for example, when having water or
when to use certain pesticides. Thanks to combination
of sensors such as humidity, temperature, and light and
so on .
 Avoid the risk of frost, as well as any plant diseases or
you can control the level of irrigation based on soil
moisture and leaf wetness.
IMPLICATIONS OF HOT POTATOES
The precision agriculture has the ‘aim of
 optimizing the production,
 taking into account local soil and climatic variations.
All this involves extremely precise control of vital
parameters for vineyards and greenhouses, so
that irrigation and climate control correspond to
local conditions.

In the greenhouses solar radiation:
 temperature and CO2 concentration are correlated to
determine the final production.
If any of these factors is limiting, it becomes
unnecessary to increase the other.
Precision Agriculture
 The main factors of the microclimate in the greenhouse
that we can control and manage are:




Temperature, CO2 concentration,
Humidity,
Intensity of radiation
and wind pressure or speed.
