Abstract
In Peer-to-Peer (P2P) content sharing, users can share their contents by contributing their own resources to one another. However, since there is no incentive for contributing resources to others, users may attempt to obtain contents without any contribution. To motivate users to contribute their resources to the service, incentive rewarding mechanisms have been proposed. On the other hand, emerging wireless technologies, such as beyond third generation cellular and Mobile WiMAX, provide high-speed Internet access for wireless users. Using these high-speed wireless access, wireless users can use P2P services and share their contents with other wireless users and with fixed users. However, this diversification of access networks makes it difficult to appropriately assign rewards to each user according to their contributions. This is because the cost necessary for contribution is different in different access networks. In this paper, we explain in detail an incentive mechanism called EMOTIVER, which improves the service quality by appropriately assigning rewards to each user even if users have various cost functions, and discuss its extensibility.
