A single-hop clustering and energy efficient protocol for wireless sensor networks

Energy efficiency is an active research area in WSNs technology. There is an extensive research work going towards this direction and existing mechanisms fail to address the problem completely due to its limited specificity. This work focuses on the idea of enhancing the network lifetime on the basis of cluster-heads (CHs) remaining energy levels. Thus, instead of changing CHs at every round for dynamic clustering, we propose two sorts of CH threshold function as energy threshold function and optimal CH range threshold function for maximizing the network lifetime. Simulation results show that our protocol maximizes the network lifetime and captures the data three times more than the other known energy-efficient protocols in the literature.
