2. INDRODUCTION
*A wireless sensor network is a wireless sensor
network consisting of spatially distributed
autonomous device using sensors to
cooperatively monitor physicalir environmental
conditions, such as temperature, sound,
vibration,pressure,motion or pollutants,at
different locations.
*A collection of sensing devices that that can
be communicate wirelessly.

3. CONTENTS
*Introduction
*Characteristics
*Applications
*Architecture for
WSN

4. *WSN Node
*Factors of WSN design
*Futures of WSN
*Advantages
*Disadvantages
*Operational challenge of
WSN
*Conclusion

5. CHARACTERISTICS
*Cross layer design.
*Heterogeneity of nodes.
*Easy to use.
*Cross layer design.
*Heterogeneity of
nodes.
*Mobility of nodes.

6. APPLICATIONS
*Military
*Environmental
*Health

*Automotive

7. ARCHITECTURE FOR A WSN
SPECIAL ADDRESSING
REQUIREMENT:
* Data centric
* Local unique
addresses. Eg:Each
node has unique
number.

8. WSN NODE
SENSOR:
*A transducer
*Converts physical
phenomenon. Eg:
heat,light, motion,
vibration.

9. SENSOR NODE:
* Basic unit
sensir network.
* Nodes deployes
either inside or
very close to the
sensed
phenomenon.

12. FUTURE OF WSN
*Sensors controlling
appliances and electrical
in the house.
*Better lightning and
heating in office
building.
* The pentagon building
has used sensor
extensive.

13. ADVANTAGES
1 IIt avoid a lot of wiring
2
It can accommodate new
device at any time
3
It is flexible to go through
physical partitions
4
It can be accessed through
centralized monitor

14. DISADVANTA
GE*Lower speed
compared to
wired network.
*Still costly at
large.

15. *More complex to
configure than
wired network.
*It does not
reduce costs for
installation of
sensors.

18. CONCLUSION
*WSN possible today due
to technological
advancement in various
domains.*Envisioned to
become an part
of our lives.
