Phase diffusion time division method for wireless communication network

This paper proposes a novel communication timing control for a wireless sensor network, named phase diffusion time division method. This is based on the mutual synchronization of coupled phase oscillatory dynamics with a stochastic adaptation, according to the history of collision frequency in the communication node. Through local and fully distributed interactions in the communication network, the dynamics self-organizes an efficient communication pattern, such that the network reduces the collision frequency by diffusion of the phase pattern, but also it sustains the sufficient throughput of communications by the stochastic adaptation. This method is designed for applications in a regular grid model of the wireless network, but it is also extended to the irregular grid model as simulation results exemplify the efficiency.
