Efficient File Sharing in P2P Network with TTL Scoped Based Searching

This Book focuses on Peer-to-peer technology, that is used for the self-organizing network so that no central service provider is needed. Research challenges include efficiency and scalability aspects and the support for location based search. We study a model for peer-to-peer file sharing. The goal is to distribute a file from a peer to multiple peers. This report describes the implementation of a bandwidth-efficient and easy to deploy TTL Scoped based search algorithm for Peer-to-Peer networks with fast file downloading feature. To implement the file sharing system, a Sockets-based messaging framework was implemented in Java, using command line interfaces. The file system enables distributed peers to present a virtual single directory to users while sharing file load across different platforms. We assume the upload/download capacity of each peer is the only bottleneck. Min-max finish time and optimal average finish time of the model are studied. Extensive results show that TTL Scoped search algorithm achieves high success rates, increased number of discovered objects, very low bandwidth consumption and to changing topologies.
