Peer to Peer File Sharing on Android

Abstract

Android provides us various functionality to perform various operations, Wifi-Direct is the part of the enhancement made in android 4.0 version. With this we can have peer to peer file sharing. In this Application named "Torrent" we used this and made an Application through which you can transfer different kind of files between two devices. Firstly the application was built and tested only for one to one communication after getting success in that we extended the application for multi-hop communication. As we worked on opportunistic network where we need to transfer the packet as soon as we get the opportunity in such an environment the application works very well. As we are using Wifi-Direct instead of Bluetooth the range and transfer rate has been an advantage. Overall this application is an effort to provide a simple multihop peer to peer file sharing application which provides the user a simple interface to work with easily workable and approachable to all kind of audiences which can perform file sharing with-out the need of any central server and internet.
