In contrast with previous uncoordinated peer-to-peer schemes, users opt-in to dedicate part of the resources they own to help the content delivery, in exchange for receiving the same service at a reduced price.

However, they also increase a user’s expectation that she will receive a fair price for the resources she provides. Addressing this issue carefully is critical in ensuring that all interested parties—including the provider—are willing to participate in such a system, thereby guaranteeing its stability. In this paper, we take a cooperative game theory approach to identify the ideal incentive structure that follows the axioms formulated by Lloyd Shapley. This ensures that each player, be it the provider or a ...
