Outline of Final Research Achievements |
We studied the mechanisms of frog choruses from the viewpoints of mathematical modeling and its application. Empirical studies demonstrate that Japanese tree frogs (Hyla japonica) show collective choruses while avoiding call overlaps with neighbors. We reproduce these phenomena by using a hybrid mathematical model in which separate dynamical models are switched depending on internal conditions of respective frogs and interactions with other frogs. Next, we proposed a novel method of the control of a wireless sensor network based of the model of frog choruses. Numerical simulation demonstrate that the proposed model can contribute to the reduction of power consumption as well as the reduction of packet collision in a wireless sensor network.
