Peer-To-Peer File Sharing in Android Devices

Abstract

Peer-to-peer file sharing is very popular on the Internet. But, to use it, one has to be connected to the Internet and it incurs significant data cost. We are developing an android application for peer-to-peer file sharing named Mobile Torrent using which files can be shared between smartphones within a campus without using the Internet. Each application user can share files and can register a request to download a file shared by any other application user even if the source is not directly connected. Initially, we have implemented the same for single hop; i.e. when two smartphones come in the Wi-Fi communication range of each other, they auto-discover each other using Wi-Fi Direct and automatically exchange required files.
