I present a time synchronization algorithm for wireless sensor networks that aims to
conserve sensor battery power. The proposed method creates a hierarchical tree by flooding the
sensor network from a designated source point. It then uses a hybrid algorithm derived from the
timing-sync protocol for sensor networks (TSPN) and the reference broadcast synchronization
method (RBS) to periodically synchronize sensor clocks by minimizing energy consumption.
In multi-hop ad-hoc networks, a depleted sensor will drop information from all other
sensors that route data through it, decreasing the physical area being monitored by the network.
The proposed method uses several techniques and thresholds to maintain network connectivity.
A new root sensor is chosen when the current one's battery power decreases to a designated
I implement this new synchronization technique using Matlab and show that it can
provide significant power savings over both TPSN and RBS.
Here’s what’s next.
