However, the demand for low latency, im-posed by real-time Internet of Things (IoT) applications presents some significant obstacles. This study delves into novel approaches to reducing latency within 5G MIMO setups, focusing particularly on the integration of shortened Transmission Time Intervals (TTIs) and preemptive scheduling tactics. Through simulations involving a small-scale MIMO configuration servicing multiple IoT devices, this study thoroughly evaluates the effects of these methods on transmission latency. The desired result is to demonstrate that the adoption of reduced TTIs notably mitigates overall latency, thereby augmenting the efficacy of time-sensitive IoT tasks such as industrial automation and healthcare monitoring systems. This re-search not only contributes to the theoretical progression of 5G communications but also furnishes practical insights for network operators and system designers trying to fine-tune 5G networks for evolving IoT environments. The simulation results indicate that the proposed techniques significantly reduce latency by ap-proximately 30% compared to standard configurations, particularly benefiting high-priority IoT applications. These findings highlight the effectiveness of shortened TTIs and preemptive scheduling in enhancing the performance of real-time IoT tasks within 5G MIMO networks.1 aKatsigiannis, Chrysostomos-Athanasios1 aTsachrelias, Konstantinos1 aKokkinos, Vasileios1 aBouras, Christos1 aGkamas, Apostolos1 aPouyioutas, Philippos  uhttp://telematics.upatras.gr/telematics/publications/enhancing-real-%E2%80%93-time-iot-applications-latency-reduction-techniques-5g-mimo-networks?language=en
