Wireless Sensor Networks (WSNs) are used for collection of data from the area of interest. WSNs deployment, application requirement and nature of phenomena have an effect on the generation of data. The data generated can be redundant and injection of redundant data into the network reduces the lifetime of energy constrained WSNs. In this paper, the authors propose an Efficient Data Reporting Protocol (EDRP) which filters the redundant data and thereby reduces the energy consumption of Sensor Nodes (SNs). EDRP can be tuned according to the application requirements. Simulation results show that significant energy is saved by their proposed scheme.
