This study examines ESP32-based static and dynamic load-balancing algorithms to enhance defence networks’ Wi-Fi range and traffic control. Real-time Wi-Fi scanning assessed the performance of these algorithms, covering response time, throughput, network latency, jitter, and packet loss. The static algorithm demonstrated a 5% lower average response time and 3% higher throughput than the dynamic algorithm, leading to significant improvements in jitter (from 1.01 ms to 0.80 ms) and packet loss rate (from 1.50% to 0.88%). On the other hand, dynamic load balancing reduced Access Points (APs) overload by 20% during peak periods, enhancing network stability and resource utilisation, which is crucial for defence operations. These findings highlight the contribution of ESP32-based load balancing, offering a practical solution to optimise defence network performance by enhancing throughput scalability and AP resource efficiency. The study provides essential insights into managing signal variability, congestion, and disruptions, offering valuable guidance for defence and security professionals in optimising wireless network infrastructure.
