provide a mechanism for synchronizing the local clocks of the nodes in a sensor network
used by many applications of sensor networks, such as tracking and localization.
Attacks on time-synchronization protocols:
have one main goal, to somehow convince some nodes that their neighbors’ clocks are at a different time than they actually are.Time Synchronization Protocols
