Wireless Sensor Networks (WSNs)
-
Characteristics and Challenges


Presented by:

Dr. Abedalkareem Awwad


Abstract:


Wireless sensor net
works have a wide range of application
s

in military,
environment, automation , health ,and weather prediction. The data
-
centric
nature of Wireless Sensor Networks (WSNs) and the severe resource constraints
of the sensor nodes distinguish sensor data manage
ment from other
communication networks. Both the client
-
server approach as well as the end
-
to
-
end communication principle that have been proposed for Mobile Ad Hoc
Networks (MANETs) do not suit the characteristics of WSNs. Efficient lookup
and routing of
sensor data are of great significance for WSNs, especially as the
size of these networks continues to grow. On an abstract level, structured peer
-
to
-
peer protocols, which rely on Distributed Hash Tables (DHTs) provide
O
(1)
complexity for storing and retrie
ving data in the network, seem overcome these
restrictions. However, the fact that they rely on underlayer routing techniques
leads to inefficient resource usage in the context of sensor networks. The
combination of DHTs and underlayer routing led to the e
stablishment of so
called virtual coordinate routing techniques.
