The Asynchronous Pulse Code Multiple Access scheme (APCMA) encodes information as intervals of a few pulses and can accommodate a large number of wireless devices. However, the high pulse density leads to message misdetection at a receiver. Therefore, it is necessary to smooth out the pulse density by distributing the timing of message transmission for reliable communication. In this paper, we propose a noise-induced scheduling mechanism that uses spatially correlated environmental noise to achieve synchronization and then accomplish controlled desynchronization for distribution of the timing of message transmission among receiver-less nodes. Simulation results show that our proposal can accomplish uniform message transmission by using temperature with the high thermal diffusivity as the noise signal.
