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.
