Abstract EN
This paper presents a solution for reducing the ill effects of free-riders in decentralised unstructured P2P networks.
An autonomous replication scheme is proposed to improve the availability and enhance system performance.
Q-learning is widely employed in different situations to improve the accuracy in decision making by each peer.
Based on the performance of neighbours of a peer, every neighbour is awarded different levels of ranks.
At the same time a low-performing node is allowed to improve its rank in different ways.
Simulation results show that Q-learning-based free riding control mechanism effectively limits the services received by free-riders and also encourages the low-performing neighbours to improve their position.
The popular files are autonomously replicated to nodes possessing required parameters.
Due to this improvement of quantity of popular files, free riders are given opportunity to lift their position for active participation in the network for sharing files.
Q-feed effectively manages queries from free riders and reduces network traffic significantly.
