A Comparative Study of Time Synchronization Protocols in Wireless Sensor Network

Wireless sensors network is a type of the ad-hoc network. It is comprised of many sensors which are interlinked with each other for performing the same function collectively such as monitoring the weather conditions, temperature, different kind of vibrations and sound etc. Any distributed system requires time synchronization. In particular, time Synchronization is extremely important for Wireless sensor network applications e.g. for data fusion, TDMA schedules, synchronizes sleep periods, etc. In this paper, the authors explain a different time synchronization protocols available for sensor networks, like Reference Broadcast Synchronization (RBS), Flooding Time Synchronization Protocol (FTSP) and Time Synchronization Protocol for Sensor networks (TPSN).
