Sensor Nodes (SNs) gather data in Wireless Sensor Networks (WSNs), which is pieced together at the sink. Most of the energy of SNs is consumed in transmission and reception of the data packets. Reduction in transmission of data packets greatly improves the lifetime of WSNs as it not only reduces energy of transmitting nodes but also of the receiving nodes. In this paper, the authors propose an Energy Efficient Data Gathering Protocol (EEDGP) which reduces the transmission of data packets thereby reducing the energy consumption of SNs (SNs). Simulation results show EEDGP significantly increases the life time of WSNs by reducing the transmission of redundant data.
