Energy efficient clustering in sensor networks using Cluster Manager

In order to organize the sensor nodes in a wireless communication network and to route the sensed information from the field sensors to a remote base station various techniques are available. The major problem of the sensor network is to increase the lifetime of the sensor nodes. For this reason many protocols have been established. In this paper we presents a new energy efficient clustering technique for large-scale sensor networks. By monitoring the received signal about power from its neighboring nodes, each node estimates the number of active nodes in real time and computes its optimal probability of becoming a cluster head. The goal is to select cluster heads that minimize transmission costs and energy usage. Based on the clustered architecture, we propose a new Energy Efficient Clustering Algorithm for the efficient Cluster Head selection by using a Cluster Manager (CMR). When compare to existing work the proposed technique work efficiently and reduces the energy consumption of sensor nodes.
