Design of a peer-to-peer system for optimized content replication

Abstract

This paper introduces a peer-to-peer (p2p) based system for content replication, enhanced with built-in optimization techniques. This turns out to be useful to enhance the overall system and to optimize the usage of resources. In addition, such techniques could be used to mitigate the leeching, which is the usage of resources from a remote user without contributing. Simulations are provided to compare the proposed optimized strategy to more conventional ones. © 2007 Elsevier B.V. All rights reserved.
