Abstract: In any distributed system, time synchronization plays an important role. Distributed wireless sensor networks (WSN) often require accurate time synchronization for coordination and data reliability. But precision of time synchronization is limited to scope and criticality of the application. Energy, lifetime and time synchronization are important parameters of wireless sensor network. Recursive time synchronization protocol (RTSP) can achieve these parameters effectively and efficiently. RTSP elects a reference node for time synchronization in entire network. Reference time is adjusted at intermediate node to compensate for propagation and processing delay. In this paper, a prototype of RTSP is implemented to investigate its accuracy and efficiency in the real time environment. Arduino Uno is used as microcontroller for logical design development and Xbee for communication among nodes. Prototype implementation creates a relay network using mesh topology for testing and experimentation of RTSP. Prototype shows promising results for future RTSP implementation in a larger network.
