This paper describes and validates an extension to the widely used Flooding Time Synchronization Protocol (FTSP) namely Dynamic Flooding Time Synchronization Protocol for Wireless Sensor Networks. The extension enhances FTSP by dynamically optimizing communication exchange with the dual aim of conserving energy whilst improving accuracy. This optimization is realized by altering the transmission rate of motes based on real-time monitoring and the WSN application accuracy requirements. The proposed mechanism, thus, eliminates the need with FTSP to determine and pre-configure a suitable transmission interval for a particular environment.
