Abstract

Peer-To-Peer networks work by relying on involvement of peers on tasks like resource sharing, routing, and querying of resources. Power of peer-to-peer systems come from resource sharing. If some peers do not contribute to the system, efficiency and effectiveness of the system is degrades. This situation is expressed as free-riding problem. To cope with free-riding and encourage all peers to contribute, incentive models are developed. Incentive models basically aim to encourage all peers to contribute. Main purpose of incentive models is to prevent peers which do not contribute to system and only allow peers which contribute to system for getting services.Within the context of this thesis, a trust based incentive model is developed. The proposed model has shown that trust models can be used to provide incentives. The model trained for different situations and attack types are tested in various configurations and successful results are obtained.
