Measurement of Distance in Multiagent by Acoustic Waves at Different Frequencies

抄録

In multiagent systems, each agent as a learner must decide actions by itself. Distance information between agents is needed for selecting actions, for example, in order to make routing tables. Usually we get information of a wireless signal power from a wireless network card because there is a relationship between the wireless signal power and distance between agents. But some network cards do not provide us a wireless signal power or such information. In this paper, we provide a novel distance measurement method using acoustic wave. A composite wave which consists of a direct wave and reflected waves is not a monotone decreasing because it has `nodes' which amplitude are always almost zero per wavelength. So we can not get distance information from a wave signal power. In this paper, we propose the distance measurement method with the two ore more sine waves. And experiment shows its implementability.
