This paper investigates the problem of efficient data dissemination in Mobile Ad hoc NETworks (MANETs) with high mobility. A testbed is presented; which provides a high degree of mobility in experiments. The testbed consists of 10 autonomous robots with mobile phones mounted on them. The mobile phones form an IEEE 802.11g ad hoc network to communicate with each other. A dynamic network topology is assumed, where the mobile devices form a cooperative cluster in order to exchange data packets among each other. In the authors' multimedia exchange scenario, the initial state is that one device carries all information, and the goal is to convey that information to all devices.
