Improve Performance of Wireless Sensor Network Clustering Using Mobile Relay

Wireless sensor networks sense events, collect data and forward it to the infrastructural node, called sink, for further processing and assessment. The communication from sensor node to the sink is an energy consuming task. Clustering is one of the strategies to provide communication in the sensor network. Maintenance of the clusters and re-clustering are important to improve connectivity of the network. An efficient clustering protocol reduces the energy consumption in addition to providing connectivity and communication path, because energy is a scarce commodity in wireless sensor network. The following paper proposes a clustering procedure to reduce energy consumption, reduce delay in communication and improve the connectivity of the network. The proposed algorithm aims to improve the performance and lifetime of the network by improving the above mentioned parameters.
