PictureViewer - A mobile application using network coding

This paper looks into the implementation details of network coding for a mobile application running on commercial mobile phones. The mobile application coined PictureViewer can convey pictures from one source device to many neighboring devices using WiFi. The advantage of network coding in this context is that the source devices only needs a minimal amount of knowledge about the targets received packets and therefore only a minimal amount of feedback is needed to ensure reliable data delivery. The implemented network coding algorithms are tailored to be fast and energy efficient on commercial mobile phones. The goal of the paper is therefore to investigate those algorithms and to demonstrate that network coding can be deployed on state of the art mobile phones.
