Time synchronization is a crucial component of wireless sensor networks, many applications require uniform clock information. In order to avoid network congestion and reduce the overhead of transmitting data packets , a spanning subtree based multi-channel time synchronization algorithm (SSMTS) is presented . The scheme is composed of two phases: spanning tree construction phase and time synchronization...
Wireless sensor networks (WSN) are characterized by stringent power constraints. Researchers focus on improving their power efficiency in order to allow building up networks that survive for long periods of time on limited battery resources without any human intervention. Improvements have been proposed for every hardware and software component, including every networking layer of the sensor nodes...
