A Clustering Mechanism for Energy Efficiency in the Bottleneck Zone of Wireless Sensor Networks

The bottleneck zone largely affects the overall performance of wireless sensor networks (WSNs). Research has shown that this issue can be handled to a large extent by effective load distribution strategies. This works aims at determining an efficient clustering scheme to achieve a better load distribution. A clustering scheme can effectively destitute load if a load of a particular area can be determined. So, the proposed approach creates an efficient clustering structure by selecting the energy-efficient node as the cluster head and then determines a cluster range appropriate by taking note of loads of its neighborhood. The simulation results showed that the proposed approach significantly improves the throughput and lifetime of the network.
