This study presents a framework that integrates backscatter communication (BC) and nonorthogonal multiple access (NOMA) to enhance the efficacy of unmanned aerial vehicle (UAV)-assisted mobile-edge computing (MEC) systems. Utilizing NOMA, numerous Internet of Things (IoT) devices can concurrently offload their computational tasks to the UAV, while BC facilitates energy-efficient data transmission through the reflection of ambient signals. We devised closed-form formulas for the successful computation probability (SCP) to assess the offloading performance, utilizing the Nakagami-m fading channel model. Finally, numerical findings are provided to corroborate the accuracy of our study.

摘要

This study presents a framework that integrates backscatter communication (BC) and nonorthogonal multiple access (NOMA) to enhance the efficacy of unmanned aerial vehicle (UAV)-assisted mobile-edge computing (MEC) systems. Utilizing NOMA, numerous Internet of Things (IoT) devices can concurrently offload their computational tasks to the UAV, while BC facilitates energy-efficient data transmission through the reflection of ambient signals. We devised closed-form formulas for the successful computation probability (SCP) to assess the offloading performance, utilizing the Nakagami-m fading channel model. Finally, numerical findings are provided to corroborate the accuracy of our study.
