Communication timing control is based on the mutual synchronization of coupled phase oscillatory dynamics with a stochastic adaptation according to the history of collision frequency in communication nodes. Through local and fully distributed interactions in the communication network the coupled phase dynamics self-organizes collision-free communication. In wireless communication the influence of the interference wave causes unexpected collisions. Therefore we propose a more effective timing control by selecting the interaction nodes according to the received signal strength. Copyright 2007 Y. Kubo and K. Sekiyama.
