      Time synchronization is essential in wireless sensor networks as it is
      needed by many applications for basic communication. The inherent
      characteristics of sensor networks do not permit simply applying
      traditional time synchronization algorithms. Therefore, many new time
      synchronization algorithms have been proposed, and a few of them provide
      security measures against various degrees of attacks. In this article we
      review the most commonly used time synchronization algorithms and evaluate
      these algorithms based on factors such as their countermeasures against
      various attacks and the types of techniques used.
