دانلود مقاله AN ANALYSIS OF VARIOUS PARAMETERS IN WIRELESS SENSOR NETWORKS USING ADAPTIVE FEC TECHNIQUE

M.R.Ebenezar jebarani1and T.Jayanthy2

ABSTRACT
In Wireless sensor network, since the media is wireless there will be burst errors which leads to
high bit error rate that affect the throughput. Wireless sensor networks drop the packets due to propagation
errors that lead to retransmission traffic. This paper evaluates the effect of adaptive FEC in Wireless
sensor networks. Adaptive FEC technique improves the throughput by dynamically tuning FEC depending
upon the wireless channel loss. The main aim is to achieve desire throughput with less energy
consumption. If the retransmission traffic decreases, that is error correction performed using adaptive FEC
which maximize the throughput. The other related parameters packet delivery ratio, packet loss, delay,
error rate are also being analyzed. The algorithm reduces the retransmission traffic by using Adaptive
FEC technique thus improving the throughput and reduces the error rate.

ABSTRACT
A typical wireless sensor network consists of many small sensors
that collect instrument data around their locations and
forward it to a central location for data processing. These
networks can be deployed to monitor livestock and agricultural
assets, products in a store, patients in a hospital, and
so on. In many cases sensors have to be densely deployed,
and collisions or overhead due to collision avoidance will
considerably degrade the system performance below an application’s
required levels. With the decreasing cost of radio
devices the obvious solution to this problem is the use
of multiple receivers on different radio channels. However,
we show that if receivers can be placed in different locations
then increasing the number of receivers on a single
channel will increase the rate of the capture effect and decrease
collision losses, while also increasing the fairness of
the transmitters’ radio links. Not only can this single channel
approach be more effective than using multiple channels,
it is also required for some techniques, such as localization,
where each receiver must be able to detect a transmission
from any transmitter. We also show that the optimal choice
between these two solutions is influenced by the radio attenuation
rate and the number of receivers in the system.
