تحليل الأداء الزمني لخطوط الاتصال اللاسلكي تحت تأثير التشويش باستخدام نظرية الشبكات العشوائية

Abstract

Electronic jamming is one of the most significant challenges facing the effectiveness and reliability of wireless communication links, particularly in critical environments such as maritime communications. This study aims to analyze the temporal performance and efficiency of these links under variable electromagnetic conditions with intentional jamming. A methodology based on Stochastic Network Theory was employed to model the transmission process as a stochastic process, taking into account different operational scenarios (normal mode, jamming mode, and transition to protection system). Mathematical models were derived for the distribution functions of the mean time of successful transmission and stability indicators under these conditions. The results of computer simulations using MATHCAD demonstrated that jamming detection time and switching to the protection system is the most critical criterion for overall efficiency. The research also proposed an automated algorithm for rapid jamming detection based on flow analysis and message serial numbers, which significantly reduces detection time and increases link stability to values exceeding 0.99. This study provides a theoretical and practical framework for enhancing the design of communication systems to make them more resilient and reliable against intentional jamming.
