QWSNs combine quantum communication principles with traditional wireless sensor network technologies, offering the potential for improved security, energy efficiency, and signal quality. TRS, a concept from signal processing and quantum mechanics, focuses transmitted signals back toward the receiver, compensating for noise, interference, and fading effects. By applying TRS to QWSNs, we aim to optimize throughput, reduce latency, and enhance energy efficiency in challenging communication environments. The paper presents a theoretical framework for integrating TRS into QWSNs, including mathematical formulations for its impact on key network performance metrics. We also consider real-world channel models, such as Rayleigh and Rician fading, along with network interference, to demonstrate how TRS can improve communication in practical settings. The discussion extends to the broader potential of TRS in quantum communication systems, particularly in **Quantum Key Distribution (QKD)**, **quantum entanglement**, and **quantum networking** applications. The findings highlight TRS as a promising approach to optimize quantum communication in sensor networks and provide a foundation for future research in the intersection of quantum technologies and wireless networks.

Greater security pledges, reduced latency, and increased energy efficiency are now more important than ever due to the Wireless Sensor Networks' (WSNs) explosive growth. Although they work well for many distributed systems, traditional cryptography techniques are slow for mission-critical sensor applications and are still susceptible to new quantum attackers. In order to improve WSN security and performance, this study proposes a unified framework that combines Quantum Key Distribution (QKD) with 5G communication capabilities. This expanded work builds on previous simulation studies before and after the third Doctoral Committee evaluation. It includes a refined 5G-enabled architecture, a lightweight QKD model, and extensive simulations that capture energy consumption, bandwidth variation, latency, Packet Delivery Ratio (PDR), and Quantum Bit Error Rate (QBER). The findings show that while QKD maintains robust security even under controlled levels of quantum noise, 5G-assisted WSNs greatly increase bandwidth usage and communication delay. The proposed 5G–QKD WSN consistently delivers decreased latency, stable PDR, and enhanced security without imposing severe energy penalties, according to comparative simulations versus classical LEACH and MULE-based baselines. These results lend credence to the viability of hybrid quantum-enhanced wireless networks for critical infrastructure monitoring, smart environments, and future extensive IoT deployments.
