| Abstract | In this paper, we propose and evaluate a selforganizing communication mechanism for wireless sensor networks where a large number of sensor nodes are deployed. To accomplish application-oriented periodic communication without any centralized controls, we adopt traveling wave phenomena of a pulse-coupled oscillator model by regarding sensor nodes as oscillators and emission of radio signals as firing. We first investigate conditions of a phase-response curve to attain wave-formed firing patterns regardless of the initial phase of oscillators. We adopt the derived phase-response curve to accomplish the desired form of message propagation through local and mutual interactions among neighboring sensor nodes. Through simulation experiments, we confirm that our mechanism delivers sensor information to / from a designated node in a more energyefficient manner than other method, although it takes time to generate a traveling wave. |
