Synchronization algorithm for hybrid control networks: CAN and wireless control networks

Abstract

This paper proposes a synchronization algorithm for hybrid control networks in industrial environments. The proposed algorithm minimizes synchronization error, which is caused from channel, propagation, and frequency delay. The modified RBS and the offset synchronization methods can be updated by adjustment parameters of proposed algorithm. For the performance analysis, throughput and data transmission time between CAN and wireless devices are investigated. The simula tion results show the performance in terms of the availability of the proposed algorithm.

A model for the classification and survey of clock synchronization protocols in WSNs

“…In order to reduce the energy consumption, and the number of packet transmissions for clock synchronization, Jain and Sharma have proposed the Optimal Performance Reference Broadcast Synchronization (OPRBS) [35] protocol which performs clock synchronization based on a broadcast reference rather than the timestamp exchange given in RBS. In the recent past, there have been many protocols [36,28,37,38] proposed using the basic idea of RBS and these protocols try to improve over the RBS by adding some new features.…”
