Extending Lifetime of Wireless Sensor Networks using Forward Error Correction

Suresh Upandra Donapudi, Christian Olesen Obel, Jan Madsen

AbstractCommunication between nodes in Wireless Sensor
Networks (WSN) is susceptible to transmission errors caused
by low signal strength or interference. These errors manifest
themselves as lost or corrupt packets. This often leads to retransmission,
which in turn results in increased power consumption
reducing node and network lifetime.
In this paper, we implement and evaluate a convolution code
FEC with Viterbi decoding on Mica2 nodes to explore the
possibility of extending the lifetime of a degrading WSN. We
present results which suggest that our approach could be used
in a WSN when increasing distance and channel noise degrade
the network.
