One of the major issues in wireless sensor network is developing an energy-efficient routing protocol. LEACH is very effective in enhancing lifetime of the nodes from routing aspect. This paper proposes the scheduling of energy efficient cluster nodes close to the base station called EECL algorithm. Both LEACH and EECL algorithms have been varied with different transmission radii and compared for the improvement of network lifetime. Simulation results show that there has been significant improvement in energy conservation of wireless sensor networks with EECL. randomized rotation of local cluster base stations evenly distribute the energy load among the sensors in the network. It uses localized coordination to enable scalability and robustness for dynamic networks and incorporates data fusion into the routing protocol to reduce the amount of information that must be transmitted to the base station. In this paper, an improved LEACH protocol for data gathering and aggregation is proposed. Such innovation can extend the lifetime of the whole network due to much less energy dissipation for data transmission to base station (2).
