IEEE 1588 is a recently developed protocol for clock synchronization in a wired network with micro-second precision. Clock synchronization is usually a challenge in industrial real time applications such as robotics, industrial controls, smart power grids and Telecommunications. In this paper, we have implemented the IEEE 1588 Precision Time Protocol on a compact Raspberry Pi based Embedded System. We have analyzed the performance of the Precision Time Protocol over both wireless local area network and wired networks under real time conditions. Also, we have made a comparison of the synchronization performance over two communication media, guided and unguided with variable path losses. Through this study, we can evaluate the performance of Precision Time Protocol for different applications and determine the best possible operating parameters for different deployment scenario.
