A mobile ad hoc network is a dynamically self organizing network without any central administrator or infrastructure support. It is composed of mobile terminals that communicate one to the other through broadcast radio transmissions, i.e., transmissions that reach all the terminals within the transmission power range, if two nodes are not within the transmission range of each other, other nodes are needed to serve as intermediate routers for the communication between the two nodes. In ad hoc wireless networks, communicating data is vulnerable to lots of potential attacks due to their characteristics of having dynamic topology, limited bandwidth and energy constraints indeed, data security is an important issue in such environment. In general, the attacks are classified as passive and active.
