摘要：The mean field game theory provides a powerful mathematical tool for problems with a large number ofplayers. In the existing system, a novel game theoretic approach with multiple players for security is used in MANETs.The existing scheme can enable an individual node in MANETs to make strategic security defense decisions withoutcentralized administration. In addition, since security defense mechanisms consume precious system resources (e.g.,energy), the existing scheme considers not only the security requirement of MANETs but also the system resources.Moreover, each node in the existing scheme only needs to know its own state information and the aggregate effect ofthe other nodes in the MANET. This paper utilizes game theory to propose a series of optimal puzzle-based defensemechanism for security enhancement in MANETs. In doing so, the solution concept of Nash equilibrium is used in aprescriptive way, where the defender takes his part in the solution as an optimum defense against rational attackers.Proposed scheme is based on the Sequential Probability Ratio Test which is a statistical decision process for tacklingthe mobile replica detection problem. This study culminates in a strategy for handling distributed attacks from anunknown number of sources.
