Wireless ad-hoc sensor network are becoming popular to collect data from the area of interest. But for data collection purpose nodes in the network must be synchronized with each other or with the global clock. Synchronization is needed for Media Access Control (MAC) protocol such as TDMA. Wireless sensor networks have limited battery energy, because they are small in size. All these requirements of wireless sensor networks demand an accurate and energy efficient synchronization protocol. The RTSP algorithm is designed to achieve network wide clock synchronization with good accuracy and to save battery energy.
