Abstract

Peer-to-Peer systems are designed to share resources of each computer for the common good of everyone in the system. As more and more p2p applications have been deployed, an important problem occurs that is the absence of incentive mechanism which encourages participants to contribute their resources to the system. To solve this problem, we present a novel mechanism of fair sharing, which intends to ensure that the resources amount consumed by one node is in proportion to that it contributes to the system. Moreover, this mechanism is able to defend itself against malicious attacks to some extent. Simulation results show that the commutation overhead of this mechanism is small in a very large scale.
