Executive Summary

In this paper a performance evaluation of network coding for cooperative wireless networks is carried out. Implementing network coding on commercially available mobile devices, the performance is presented in terms of throughput, delay and energy consumption. In contrast to purely cellular systems, where the mobile devices are only connected to the base station, in cooperative wireless networks, the mobile device, in addition to the cellular communication, establishes short range links to neighboring mobile devices within its proximity. In prior work it has been shown that the newly formed cooperative cluster, also referred as wireless grid, can offer each participating mobile device a better performance in terms of data rate, delay, robustness, security, and energy consumption in contrast to any stand alone device.
