EEDAC-WSN: Energy Efficient Data Aggregation in Clustered WSN

摘要

One of the primary challenges in Wireless Sensor Networks (WSNs) is energy efficiency. In the last decade WSNs have found its application in wide range of applications producing huge amount of data. Energy efficiency of a clustered WSNs can be improved, if size of data being transmitted in the network is reduced. In this paper, we present an energy efficient data aggregation scheme for clustered wireless sensor network (EEDAC-WSN). It reduces intra-cluster communications by allowing cluster member nodes to send small sized control frames followed by relatively detailed frames from nodes selected by the cluster head node. The proposed work can dovetailed with any clustering scheme, we have used it with LEACH for the purpose of simulation. The results obtained are substantial in terms of network stability period and lifetime.
