Clock Synchronization Protocols and Models for Wireless Sensor Networks

Clock synchronization is a critical aspect in the operation of Wireless Sensor Networks (WSNs), ensuring that sensor nodes maintain accurate time for coordinated communication and data processing. Various clock synchronization algorithms have been developed to address the synchronization challenges in WSNs, aiming to align the clocks of distributed nodes efficiently. These algorithms play a crucial role in achieving synchronization by compensating for clock drift, which can significantly impact the accuracy of timekeeping among sensor nodes. Timing constraints are fundamental in WSNs, as they influence network performance and data transmission reliability. Addressing timing constraints is essential for optimizing network operations and ensuring timely data delivery. In this paper we analysed various synchronization protocols, Algorithm and techniques. Finally, we compared features of TPSN and RBS protocols, based on accuracy, robustness TPSN is best one.
