Energy‑Aware SWIPT Systems for Low‑Power Wireless Sensors and IoT Devices

Abstract

The swift expansion of low-power wireless sensor networks and Internet of Things (IoT) devices has heightened the demand for sustainable and energy-efficient communication technologies. This study examines energy-efficient Simultaneous Wireless Information and Power Transfer (SWIPT) systems as a feasible approach to mitigate energy limitations in specific situations. A simulation-based study methodology is utilized to evaluate the performance of two principal SWIPT techniques: Power Splitting (PS) and Time Switching (TS). The system is modeled based on important factors like transmission power, channel conditions, and how well it converts energy. Metrics including energy efficiency, throughput, harvested energy, and network longevity are used to measure performance. The results show that energy-aware SWIPT greatly improves system performance. In most cases, the PS technique works better than the TS technique because it can continuously collect energy. The study also points out the trade-off between getting energy and sending information, which shows how important it is to fine-tune the parameters. In general, the results show that energy-aware SWIPT systems may successfully extend the life of devices and make communication more efficient. This makes them great for next-generation IoT applications.
