Efficient Data Reporting Protocol for Wireless Sensor Networks

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, we 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 our proposed scheme. Effect of two parameters (acceptable limit and Check) used by EDRP has also been analyzed. Simulation results show that acceptable limit greatly effects the energy consumption of the nodes.
