Synchronization method in heterogeneous communication networks with high density of devices with limited computing resources

Abstract

A methodological solution for improving the time synchronization technology in heterogeneous communication networks with an increased density of devices with limited computing resources is presented. The relevance of this study is due to the fact that modern communication networks are becoming increasingly heterogeneous and can contain a large number of devices with limited computing resources, which also require synchronization, like classical communication networks. Not all devices with limited computing resources can contain Ethernet ports for receiving time stamps via PTP, so it is necessary to consider new possibilities for distributing a single accurate time. Future heterogeneous communication networks with a high density of devices with limited computing resources require solutions that can ensure synchronous and consistent operation with minimal computational costs, which is especially important for improving the efficiency of future communication networks under conditions of limited computing resources. The authors propose a method for distributing information about a single accurate time in heterogeneous communication networks with an increased density of devices using the CAN interface. Main positive effects: 1) Development of a new solution for synchronization in heterogeneous communication networks with an increased density of devices with limited computing resources; 2) Reducing the cost of implementing synchronization functionality in such networks by eliminating equipment that can unnecessarily complicate the end device; 3) Improving the quality of operation of heterogeneous communication networks with a high density of devices with limited computing resources in real time.
