An Energy-efficient algorithm using layer heads for Software-Defined Wireless Sensor Networks

Software-defined networks (SDN) is an era which poses a number of challenges on energy. Minimizing energy consumption in wireless SDN is now essential and challenging. In this paper, we propose the concept of layer heads using which the energy consumption is optimized. We further reduce the energy consumption using the optimal number of energy spaces and topology type. The proposed approach is tested with varied topologies and the results show that the energy levels are conserved in software-defined wireless sensor networks (SDWSN).
