The proposed resource allocation framework can be applied in real-world IoT networks by optimizing the energy efficiency of communication systems supported by active STAR-RIS technology. By jointly optimizing the beamforming, phase shift matrices, and element selection at the active STAR-RIS, as well as the power splitting ratio of users and transmit beamforming at the base station, the system can achieve significant improvements in energy efficiency. This optimization is crucial for IoT devices with limited energy storage to ensure reliable communication while mitigating power constraints.
In real-world IoT networks, implementing this framework can lead to enhanced coverage, increased capacity, and improved reliability for a large number of distributed devices. By leveraging SWIPT technology and active STAR-RIS elements intelligently based on optimized resource allocation strategies derived from this framework, IoT networks can efficiently manage both information transmission and energy harvesting requirements.
