- 초록
- Time synchronization is essential in sensor network applications such as object tracking, consistent state updates, duplicate detection and temporal order delivery. In addition, reliability issues and fault tolerance in sophisticated sensor networks have become a critical area of research today. This paper proposes a Lightweight Fault Tolerant Time Synchronization (LFTTS), an extension of Fault Tolerant Time Synchronization (FTTS), for wireless sensor networks which takes their energy limitations and faults into consideration. Simulation results show that LFTTS has improved performance in the number of messages when faults occur.
