This paper addresses the synchronization rate of weakly connected Pulse-Coupled Oscillators (PCOs). The authors prove that besides coupling strength, the phase response function is also a determinant of synchronization rate. Inspired by the result, they propose to increase the synchronization rate of PCOs by designing the phase response function. This has important significance in PCO-based clock synchronization of wireless networks. By designing the phase response function, synchronization rate is increased even under a fixed transmission power. Given that energy consumption in synchronization is determined by the product of synchronization time and transformation power, the new strategy reduces energy consumption in clock synchronization. QualNet experiments confirm the theoretical results.
