Opportunistic mobile social network is a type of delayed tolerant network, where nodes with mobility contacts each other through short range wireless communications. Recently, many related applications are emerging, such as Firechat. However, message dissemination in opportunistic mobile social network is a challenging task. We propose collaborative network coding that enables users to take part in improving the performance of using network coding for message dissemination. The proposed method is evaluated by trace data conducted by participants who may not know each other in advance for a more realistic simulation of real world opportunistic mobile social network. Simulation result shows that our proposed method out performs flooding based message dissemination.
