Design and Performance Analysis of a Wireless CCTV Surveillance Network for Rural Road Safety: A Case Study in Alrujban City, Libya

The growing use of video surveillance systems requires reliable communication networks capable of supporting high-quality real-time streaming. This study evaluates the performance of a wireless network designed for CCTV transmission using the NS-3 simulation platform. The proposed network follows a star topology and consists of four communication links with different distances and bandwidth capacities to examine their behavior under varying traffic loads. This work is part of a broader research effort aimed at designing an efficient communication network to support road safety monitoring and traffic surveillance in mountainous urban environments. It also seeks to provide technical insights that may assist local authorities in developing reliable monitoring infrastructures and improving traffic management. The evaluation focuses on key Quality of Service (QoS) metrics, including throughput, delay, jitter, and packet loss. The results show that higher-capacity links maintain stable throughput and low delay under increased traffic load, while longer-distance links begin to experience congestion as the offered traffic approaches their capacity limits. These findings highlight the importance of link capacity in network performance and confirm that a properly designed star-based wireless infrastructure can effectively support traffic surveillance systems in geographically challenging environments.
