A Novel Weighted Clustering Based Approach for Improving the Wireless Sensor Network lifetime

Great lifetime and reliability is the key aim of Wireless Sensor Network (WSN) design. As for prolonging\ud lifetime of this type of network, energy is the most important resource; all recent researches are focused on more\ud and more energy efficient techniques. Proposed work is Weighted Clustering Approach based on Weighted\ud Cluster Head Selection, which is highly energy efficient and reliable in mobile network scenario. Weight\ud calculation using different attributes of the nodes like SNR (Signal to Noise Ratio), Remaining Energy, Node\ud Degree, Mobility, and Buffer Length gives efficient Cluster Head (CH) on regular interval of time. CH rotation\ud helps in optimum utilization of energy available with all nodes; results in prolonged network lifetime.\ud Implementation is done using the NS2 network simulator and performance evaluation is carried out in terms of\ud PDR (Packet Delivery Ratio), End to End Delay, Throughput, and Energy Consumption. Demonstration of the\ud obtained results shows that proposed work is adaptable for improving the performance. In order to justify the\ud solution, the performance of proposed technique is compared with the performance of traditional approach. The\ud performance of proposed technique is found optimum as compared to the traditional techniques
