Wireless sensor network (WSN) consisting of a large number of sensor nodes is effective for gathering data in a variety of environments. Since the sensors operate on battery of limited power, it is a challenging task to design an efficient routing scheme which can minimize the delay while offering high energy efficiency and long network lifetime. Achieving both energy efficiency and scalability at the same time is a challenging task in wireless sensor networks. In this paper a new energy efficient hierarchy-based clustering routing protocol (EEHCR) is proposed for data gathering scheme for Wireless sensor networks. This is very crucial to ensure that the system operates at minimum energy with increasing scalability and network life-time. Simulation results show that the proposed routing scheme significantly reduces energy consumption and increases the lifetime of sensor network compared to other hierarchical routing protocols.
