Wireless Network Sensor Synchronization Based IEEE1588

摘要：

Wireless Sensor Network (WSN) applications, similarly to other distributed systems, often require a scalable time synchronization service enabling data consistency and coordination. As the need of synchronization becomes more and more precise, existing synchronization methods doesnt satisfy the accuracy. Precise Time Protocol (PTP, IEEE1588) bases on multicast and meet the accuracy, but the protocol doesnt discipline the clock in sync interval, a simple and reliable frequency compensated algorithm is introduced to resolve this question. It is verified to meet accuracy need by wireless sensor network in industrial sound and vibration measurement field.
