Cooperation in Ad Hoc Network Security Services: Classification and Survey
Since ad hoc networks are infrastructureless and self-organized, their nodes have to cooperate in order to provide a particular service such as privacy or node incentives. In this paper, the authors elaborate on the cooperation role and management within the cooperation-based security services available in the literature. Furthermore, they present a comprehensive classification of such services and discuss what type of cooperation is realized inside of them. Due to the dynamic nature of ad hoc networks, relying on a fixed infrastructure (i.e., servers, routers, public key infrastructure, etc.) turns out impractical; hence, node cooperation becomes necessary.
