Comparative Reliability Study of Wi-Fi Communication System with Bridge Network utilizing UGFT and MBPTA

Wi-Fi communication systems have become integral part of modern network infrastructure, offering flexibility and cost-effective solutions for extending network connectivity over long distances. A Wi-Fi system, also known as a wireless mesh network, is a technology that is used to create a wireless local area network (LAN) within a home, office, or other spaces to provide internet connectivity and network access to multiple devices. Unlike traditional single-router setups, a Wi-Fi system typically consists of multiple interconnected access points (nodes) distributed throughout the area to create a seamless and robust Wi-Fi network. This research paper presents a thorough examination of the reliability of Wi-Fi communication systems, using bridge networking setup focusing on their performance, robustness, and fault tolerance. The two techniques namely, universal generating function technique (UGFT) and Matrix Based Path Tracing approach (MBPTA) are employed to evaluate the reliability function of the proposed system with five different elements that are connected in bridge structure. Firstly, a wireless communication system is modeled to estimate the reliability function of the system via both techniques. Secondly, in order to quantify the probability of the failure of the component, we assess the tail signature, which will allow the signature reliability evaluation of the system. Thirdly, the minimal signature, predicted lifespan and actual cost rate are derived for the proposed system. The purpose of this work is to evaluate all these outcomes and then compare their performance on the basis of their results, which are yielded by both applied approaches i.e. UGFT and MBPTA.
