Hemappa B, Manjaiah D. H., Rabindranath Bera, Shylaja B. T. . An Energy-Efficient Re-Clustering and Data Reporting Algorithm for Energy Constrained Wireless Sensor Network. International Journal of Computer Applications. 85, 10 ( January 2014), 38-44. DOI=10.5120/14879-3284
Wireless sensor networks consist of tiny sensors powered by low power battery and in most of the applications sensors are deployed to monitor the unattended areas. As sensor nodes are energy constrained in the network, energy efficiency is an important factor and should be considered during the protocol design phase. In this article we propose a robust, power-aware in-network clustering protocol to increase the network lifetime, which is based on parameters like residual energy, distance to the base station and proximity of the base station. The proposed cluster head selection protocol offers an efficient way of balancing the energy among member nodes of the cluster with considerably lesser energy consumption. Proposed novel algorithm is experimented in Matlab simulator and results shows significant improvements when compared to LEACH algorithm. The performance is evaluated by considering the impact of energy balancing among the nodes and network lifetime efficiency in WSN.
