"The text comprehensively discusses soft computing and decision-making techniques like the fuzzy analytic hierarchy process, fuzzy analytic network process, and fuzzy TOPSIS. It further covers a wide range of wireless communication with emerging computational intelligent trends. The text explores the role of wireless technologies in applications touching on various spheres of human life with the help of hesitant fuzzy sets-based computational modeling. This book: Discusses the Internet of Things and cloud computing technologies in promoting cyber security. Highlights the impact of the relationship between security and sustainability, usability, and dependability during securing cyber communication. Evaluating the importance of artificial intelligence and machine learning-based techniques, quantitatively and empirically. Discusses applications of adaptive and learning techniques for secure estimation. Showcases various risks and uses of a multi-criteria decision-making method to manage risks. The text is primarily written for senior undergraduate, graduate students, and academic researchers in the fields of electrical engineering, electronics and communication engineering, computer engineering, and information technology"--
