Time synchronization plays an important role in distributed systems. 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 any wireless sensor network. Flooding Time Synchronization Protocol (FTSP) and Recursive Time Synchronization Protocol (RTSP) are two state of the art protocols for time synchronization in WSNs. In this paper, a comparative analysis of both protocols under two different topologies i.e. bus and tree, using message count as performance parameter. Xbee Pro and Arduino Mega are used for communication and logical design implementation of both protocols, respectively.
