A wireless ad hoc network (MANET) is a collection of autonomous nodes or terminals that communicate with each other by forming a multihop radio network and maintaining connectivity in a decentralized manner. MANET is characterized by a rapidly changed topology. As a result packets select different multi-hops paths to reach their destinations. Even though packets are somehow independent from each other, there are still some hidden relations (patterns) among them. These relations may be utilized to give useful information to different MANET protocols. In this work, association rules technique is applied in time domain to obtain these hidden relations.
