Comprehensive and Effective Techniques Used to Improve Low Latency in 5G Communication

Abstract

Introduction: The advent of 5G technology is poised to revolutionize a wide range of industries by enabling ultra-low-latency communications. However, reducing latency remains a significant challenge due to the complexities of traditional network infrastructures and the propagation delays associated with long-distance signal transmission. Latency is a critical factor in the performance of applications such as autonomous vehicles, industrial IoT, and real-time communications, where even minimal delays can result in performance degradation. This paper explores innovative techniques to address the challenges associated with reducing latency in 5G networks.

Objectives: The primary objective of this paper is to identify and analyze two key approaches for minimizing latency in 5G networks: (1) reducing propagation delay and (2) optimizing network architecture. These objectives are central to achieving the low-latency performance required for next-generation 5G applications.

Methods: For network architecture optimization, edge computing is integrated to process data closer to the source, minimizing the time spent in backhaul transmission. Additionally, we advise using Software-Defined Networking (SDN) for dynamic traffic management, which enables real-time adjustments to improve latency, and putting in place effective routing algorithms that minimise packet processing delays.

Results: The integration of small cell base stations and mmWave frequency bands is expected to substantially reduce signal propagation delays, as these technologies shorten the transmission distance between the source and destination. The implementation of edge computing contributes to a significant reduction in backhaul latency, while efficient routing algorithms and SDN-based traffic management ensure optimized data flow and minimal processing delays. Preliminary simulations and analysis suggest that these combined techniques can effectively meet the stringent latency requirements of 5G applications, particularly in scenarios demanding high throughput and real-time communication.

Conclusions: Achieving low-latency performance in 5G networks is essential for the successful deployment of future technologies that rely on real-time communication. This paper demonstrates that reducing propagation delay and optimizing network architecture through strategies like small cell deployment, mmWave utilization, edge computing, and dynamic traffic management can significantly enhance latency performance. These findings contribute to the ongoing effort to design 5G networks that can support the diverse and demanding applications of the next-generation digital landscape.
