This paper presents an adaptation of peer-to-peer diffusion strategies of video over mobile links based on the use of multiple description coding. The system architecture, including the used overlay algorithm (the unstructured GIA algorithm) and video coding with multiple description coding (MDC), are presented as well as their interest in this context. Simulation results illustrate the approach, showing the interest of using MDC vs. a single description coding solution. The proposed simulation framework involves an H.264/AVC video codec with two descriptions and a simple adaptation of the overlay algorithm.
