Abstract
With the rapid expansion of wireless networks and mobile computing applications, the quality of service (QoS) of mobile ad hoc networks (MANETs) has garnered growing attention. Ensuring QoS in a MANET system requires careful consideration of security issues. Attacks on a QoS distortion system without the protection of a security mechanism might result in subpar QoS performance, interference with resource use, or even failure of QoS provisioning. Traditional security measures cannot be applied because to the characteristics of MANET, which include limited processing and communication power and diversity of static topology. As a result, new security technologies are unavoidable. Nevertheless, not much research has been done on this subject. QoS and MANET system security are covered in this article. Consequently, the goal of this research is to create techniques for routinely evaluating security design reviews in order to make sure that all vulnerabilities, including security vulnerabilities, have been found, fixed, and their cause explained. Determine the system's fundamental security and protection needs by analyzing and determining its requirements. We create a network model using GloMoSim, specify node locations, communication features, and technology, and see if there are any vulnerabilities that could pose a security risk.
