Distance Based Energy Efficient Selection of Nodes to Cluster Head in Homogeneous Wireless Sensor Networks
Wireless Sensor Networks (WSN) provide the availability of small and low-cost sensor nodes with capability of detecting, observing and monitoring the environment, along with data processing and communication. These sensor nodes have limited transmission range, processing and storage capabilities as well as their energy resources. Routing protocols for wireless sensor networks are responsible for maintaining the energy efficient paths in the network and have to ensure extended network lifetime. In this paper, the authors propose and analyze a new approach of cluster head selection by a homogeneous sensor node (having same initial energy) in wireless sensor network, which involves choosing the cluster head which lies closest to the midpoint of the base station and the sensor node.
