[IEEE CSS Video Clip Contest 2014 Submission] 

In this video, we present a new control theoretic distributed time synchronization algorithm, named PISync, in order to synchronize sensor nodes in Wireless Sensor Networks(WSNs). PISync algorithm is based on a Proportional-Integral (PI) controller. It applies a proportional feedback (P) and an integral feedback (I) on the local measured synchronization errors to compensate the differences between the clock offsets and clock speeds. PISync has several advantages over existing protocols in the WSN literature, namely no need for memory allocation, minimal CPU overhead and code size independent of network size and topology, and graceful performance degradation in terms of network size.
