Game theoretic analysis of cooperation enforcement in mobile ad hoc networks
Pietro Michiardi · 2003
This paper focuses on the formal assessment of the properties of cooperation enforcement mechanisms used to detect and prevent selfish behavior of nodes forming a mobile ad hoc network. Taking as a reference the CORE mechanism introduced in [9], we present two alternative approaches based on game theory that provide a powerful analytical method to study cooperation between self-interested players. We demonstrate that the formation of large coalitions of cooperating nodes is possible only when a mechanism like CORE is implemented in each node. Game theory also provides further insight to features of CORE such as the convergence speed to a cooperative behavior.
