TY - JOUR ID - TI - Enhanced system for ns2 trace file analysis with network performance evaluation Enhanced system for ns2 trace file analysis with network performance evaluation AU - Jawad Alkenani Jawad Alkenani PY - 2022 VL - 1 IS - 2 SP - 119 EP - 130 JO - Iraqi Journal of Intelligent Computing and Informatics المجلة العراقية للحوسبة الذكية والمعلوماتية SN - 27912868 27912868 AB - One of the critical challenges facing operators around the world is how to ensure that everything is running smoothly as well as how to analyze the performance of the network. Nonetheless, the analytic system must be precise, user-friendly, and quick enough to depict network performance in real time. Network performance is essential for ensuring service quality. In this light, the Network Simulator NS-2 is generally employed for network research on the widely-used UNIX and Windows systems. Next, the network scenarios are generated using network simulation scripts, and upon completion of the simulation, trace files that record network events are generated. Information that might be utilized in a performance study could be recorded in trace files. This could include the total number of packets sent, their arrival times, any delays or losses, and so on. This trace file analysis problem arises mostly because NS-2 does not provide any visualization options for analyzing simulation results (trace files). A system is proposed to analyze the NS2 trace file and facilitate data extraction and evaluation. The main feature of this system is the Java language for network performance evaluation. And to prove the validity of the system, the system was compared with the Trace graph, where the speed of the new system was very high.

Network performance is one of the most important problems to resolve, thus the monitoring system must be accurate, user-friendly, and fast enough to disclose network performance in real time. Therefore, all systems, notably in businesses, use Network Simulator NS-2 for network exploration. Following the creation of scripts and scenarios for network simulation, this simulator creates trace files that detail occurrences in the simulated network. Information useful for performance analysis may be found in trace files, such as the total number of packets sent, their arrival times, and any delays or losses along the way. The primary issue is that NS-2 lacks visualization capabilities for analyzing simulation results (tracing files). A new analysis system for tracking files has been proposed, which has proven its worth compared to the Trace graph method. Thus, NS-2 trace analyzers are intended to retrieve performance data. This works with a high-quality Java service, to make it easy to get performance measurements of the output trace file from NS-2 and see network performance. A potential direction for future research in our system is discovered network monitoring is dependent on multi-criteria also known as (multi-objective). Such a notion could draw inspiration from other evolutionary algorithms in real applications, namely genetic algorithms, and genetic programming, which may enhance the performance of the proposed system.
