Improving IoT Network Lifetime Through HHO-MPPT optimized Solar Energy Harvesting

The principal contribution of this study lies in creating an effective solar energy harvesting system intended to address the energy limitations experienced by batteries in Internet of Things (IoT) networks. Ideally, IoT network nodes equipped with optimized Solar Energy Harvesting systems should operate for extended periods. To achieve this goal, we propose the utilization of Maximum Power Point Tracking (MPPT) based on Harris Hawks Optimization (HHO) controllers. This strategy aims to optimize solar power extraction, consequently boosting overall system efficiency. We’ve implemented our methodology in MATLAB/Simulink and assessed its performance using a range of performance metrics. The results demonstrate the efficiency of our method, which is further substantiated through a comparative analysis with analysis with two traditional techniques. Our proposed method achieves maximum power tracking performance in photovoltaic (PV) systems in both cases of stable and variable weather conditions.
