In this chapter, we review time synchronization attacks in wireless sensor networks. We will first consider three of the main time synchronization protocols in sensor network in sections. In section we discuss applications of time synchronization in sensor networks. In section we analyze possible security attacks on the existing time synchronization protocols. In section we examine how different sensor network applications are affected by time synchronization attacks. Finally in section we propose possible countermeasures to secure the time synchronization protocols.
