In a peer-to-peer network, nodes are typically required to route packets for each other. This

Free riding in peer-to-peer (P2P) networks poses a serious threat to their proper operation.
Here, the authors present a variety of approaches developed to overcome this problem …

Trust research has become a key issue in the last few years as a novel and valid solution to
