This paper looks into the implementation details of random linear network coding on the Apple iPhone and iPod Touch mobile platforms for multimedia distribution. Previous implementations of network coding on this platform failed to achieve a throughput which is sufficient to saturate the WLAN interface. In addition to previous works we compare new implementations based on two different Galois fields: GF(28 ) and GF(2). Using the binary Galois field allows us to ensure high throughput and low computational requirements on mobile devices with limited resources. We have implemented this approach and achieved synthetic encoding/decoding throughput of up to 36/29 MB/s on a third generation iPod Touch 32GB which exceeds the results of other researchers by two orders of magnitude.
