Gradient Descent Algorithm Inspired Adaptive Time Synchronization in Wireless Sensor Networks.

This paper proposes another direction to implement a lightweight synchronization service for wireless sensor nodes. To this end, we present gradient descent synchronization (GraDeS), a novel multi-hop time synchronization protocol based upon gradient descent algorithm. We give details about our implementation of GraDeS and present its experimental evaluation in our testbed of MICAz sensor nodes. O...
