| Research Abstract |
We proposed self-organizing transmission scheduling mechanisms for periodically gathering sensor data at a base station in wireless sensor networks. In the proposed mechanisms, sensor nodes self-organize message transmissionand sleep timings. To achieve self-organizing control of sensor networks, we apply phase-locking and anti-phase synchronization in a pulse-coupled oscillator model. Simulation experiments confirm that our mechanism significantly improves the data gathering ratio and energy-efficiency in comparison with the conventional mechanism.
