Abstract :
In a structured peer-to-peer (P2P) overlay, nodes are typically required to route messages for each other. Most structured P2P overlays assume that all nodes in the overlay are altruists, which are voluntary to contribute their resources for the routing. However, as the overlays grow larger, they may include many self-interested nodes, which are unwilling to take part in the routing. As a result of the self-interested nodes, the quality of communication provided by the overlays may degrade seriously. In this paper, we propose a trust-based scheme, RouteGuard, to guard the routing in structured P2P overlays. The scheme is able to help nodes identify and avoid selfish-interested nodes in the process of routing. It also provides incentives for nodes to encourage the participation in routing. Experiment results demonstrate the effectiveness of our scheme in guarding peer-to-peer routing.
