The paper is a survey of defence mechanisms for data security and fraud detection in wireless networks. It covers various techniques used to protect wireless networks from security threats and to detect fraudulent activities. The paper also examines various fraud detection techniques that can be used to detect fraudulent activities in wireless networks. The survey includes a comparison of different defence mechanisms in terms of their effectiveness, efficiency, and applicability. The paper also identifies the limitations of the existing defence mechanisms and suggests future research directions for improving the security of wireless networks. Overall, the paper provides a comprehensive overview of defence mechanisms for data security and fraud detection in wireless networks, which can be useful for researchers, practitioners, and policymakers in the field of wireless network security.
