The proliferation of smartphones has changed our style of handling personal information and documents. They used to be stored in personal computers, but now they are becoming to be managed in the smartphone. Since this trend accelerates sharing information among many people using smartphones, efficient file transfer among smartphones is important. When a file is transferred from a smartphone to multiple other smartphones using Wi-Fi Direct, making a copy from the source to the rest of all smartphones does not necessarily provide the shortest transfer time because some link may suffer from weak wireless connection. Based on the background, we design FTroid, a system to provide a near-optimal file transfer among multiple smartphones. In this paper we describe how routers are determined in FTroid and its preliminary evaluation.
