Every node in a wireless ad hoc network is both end host (it generates its own data and routing traffic) and infrastructure (it forwards traffic for others), but rational nodes have no incentive to cooperatively forward traffic for others, since this kind of forwarding is not costless. In this paper, we use game theory to analyze cooperative mechanisms, and derive optimal criteria in forwarding.
