Energy efficient data aggregation in wireless sensor networks

Designing energy efficient data aggregation technique in clustering environment for Wireless Sensor Networks (WSNs) is a challenging task when nodes in the network are resource constrained. Data aggregation is necessary in WSNs as different sensors in the same region transmit duplicate information in the network. So to reduce the flow of this duplicate information transmitted in the network, the concept of data aggregation is necessary. The propose system also introduces an efficient mechanism of cluster head selection so that area covered by cluster head is minimum overlap area that cover the entire network. The performance of proposed scheme is evaluated using custom simulator. Simulation results prove that the proposed scheme performs better than other comparable schemes in the literature without increasing the communication overheads.
