Abstract :

Wireless sensor networks (WSNs) are highly energy-constrained networks. Once the battery lifetime is over the sensor nodes are of no use. So there is a high need for choice of suitable energy retention criterions that can reduce the energy consumption to a high extent in such networks, thereby optimizing the overall lifetime of the sensor networks. Higher energy retention means higher degree of ensurance of the delivery of data sensed by the individual nodes of the sensor network to the sink node or base station. In this paper we have analyzed data replication factor as an power retention criterion in energy sensitive wireless sensor networks. We performed the simulation in MATLAB and the results verified that data replication issue by taking a backup cluster head in a clustered sensor network is a negative factor and it degrades the performance of the network thus minimizing its network lifetime.
