Abstract: The numerical simulation of the distribution of the period before the first break down in the wireless D2D communication is analyzed while the transmitters and receivers are moving in stochastic manner. The random trajectories are generating with the use of non-stationary Fokker-Planck equation for coordinates difference on the finite plane. The effect of cashing on the duration of continuous connection is investigated. The generation method for non-stationary stochastic process trajectories enables to solve several problems in the area of stochastic control, connecting with self-organization effects, and for analysis of steady connection between transmitter and receiver devices in wireless network. © 2019, Pleiades Publishing, Ltd.
