Abstract: “The past few years have witnessed increased interest in the potential use of wireless sensor networks (WSNs) in applications such as disaster management, combat field reconnaissance, border protection and security surveillance. Sensors in these applications are expected to be remotely deployed in large numbers and to operate autonomously in unattended environments. The sensor nodes deployed in wireless sensor networks are extremely power constrained, so maximizing the lifetime of the entire networks is mainly considered in the design. In this paper, we proposed An energy efficient clustering algorithm with optimum parameters is designed for reducing the energy consumption and prolonging the system lifetime. Using a wireless sensor network, variety applications are being developed. Clustering of a sensor nodes elect to cluster head from among the sensor nodes and cluster heads to the sink node is configured a clustering and cluster head changing depends upon the available energ.”
