In this paper, the authors propose self-organizing transmission and sleep scheduling mechanisms for periodically gathering sensor data at a base station in wireless sensor networks. In their proposed mechanisms, they use a conventional self-organizing communication mechanism based on phase-locking in a pulse-coupled oscillator model to propagate sensor data from the edge of the network to the base station in order of hop counts from the base station. In addition, they propose two mechanisms to avoid collisions among sensor nodes with the same hop count, a randomization-based mechanism and a de-synchronization based mechanism based on anti-phase synchronization in the pulse-coupled oscillator model.
