NS-3 based IEEE 1588 synchronization simulator for multi-hop network

Network time synchronization using IEEE 1588 has tended to be applied to a wide network(i.e. a multi-hop network) with the aid of IEEE 1588 version 2 enhancement. However, designing a system to fulfill the desired synchronization accuracy is difficult because there are many factors that have an impact on multi-hop networks. Therefore, we developed a time synchronization simulator based on the network simulator 3 (NS-3) by developing a clock conversion model, IEEE 1588 simulation model, and application model with activation coordinated with synchronized time.
