The advances in wireless communication embedded computing and electronics have enabled the development of the low-power Wireless Sensor Network (WSN) technologies. A sensor network is a network of tiny, lightweight, battery-operated devices, known as sensor nodes. Each sensor node in a sensor network is also equipped with wireless-communication devices. Energy minimization and increase in lifetime have become the key factors for data transmission in a Wireless Sensor Network. An energy efficient protocol called Energy Efficient Relay Based Multi-hop Clustering (EEMRC) that balances the energy consumption in clusters is implemented with the help of relay nodes. Comparison of the proposed protocol with the standard LEACH protocol yielded results which showed a large improvement in network lifetime.
