BitTorrent is one of the most efficient peer-to-peer content sharing protocols. The authors took part in implementing SymTorrent: a full featured BitTorrent client application for high-end mobile phones based on Symbian OS. Recently, they have also brought the BitTorrent technology to low-end mobile by creating a prototype application, called MobTorrent. Currently MobTorrent supports only content downloading (implementation of upload functionality is ongoing). The target platform of MobTorrent is the S40 platform, which is based on the Java Micro Edition technology. This paper contains a brief overview of the BitTorrent protocol, introduces the applications and outlines the demonstration.
