Time Based Synchronization Using PCO-RBSYNC Algorithm in Wireless Sensor Networks

Abstract

since synchronization is required for several applications, time (or clock) synchronization is a vast and important area of study. Distributed databases, real-time communication, and distributed data gathering are a few examples of possible uses. Using the Pulse-Coupled Oscillator with Reference Broadcast Synchronization technique (PCO-RBSync), this research presents a new method for time-based synchronization in WSNs. Initializing the clocks, establishing a reference source, and establishing sensor nodes are all part of the first phase of network setup. The Pulse-Coupled Oscillator model enables gradual alignment of internal oscillations through pulse exchanges among neighboring nodes. Reference Broadcast Synchronization periodically broadcasts local timestamps from designated nodes to synchronize other nodes, which calculate time differences and adjust their clocks for synchronization. Continuous error monitoring, compensation techniques, and algorithm fine-tuning mitigate discrepancies, optimizing accuracy and stability. Thorough testing and evaluation validate the PCO-RBSync algorithm's effectiveness in achieving precise time synchronization in WSNs, offering a robust solution for applications such as environmental monitoring, industrial automation, and healthcare.
