Abstract

In this paper, we propose self-organizing trans mission and sleep scheduling mechanisms for periodically gathering sensor data at a base station in wireless sensor networks. In our proposed mechanisms, we 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, we propose two mechanisms to avoid collisions among sensor nodes with the same hop count, a randomization-based mechanism and a desynchronizationbased mechanism based on anti-phase synchronization in the pulse-coupled oscillator model. Through simulation experiments, we show that our proposed mechanism significantly improves the data gathering ratio and energy-efficiency in comparison with the conventional mechanism.
