ABSTRACT
Nodes in a MANET can be vulnerable to different types of attacks. These attacks can occur at different layers and can be classified into several ways. Most of the existing works that propose new and secure protocols for MANET have discussed about the issue of classifying the attacks. However, these works have largely remained focused on routing attacks. In [2,3], the authors have discussed the issue of misbehavior of nodes at Medium Access Control (MAC) layer and have attempted the classification of attacks at that layer. Some work has also been done on the attacks on application layer [4,5], but the area of focus has largely remained on sensor networks. It is also important to note that many of the existing works have made some specific and/or implicit assumptions as per their requirements.
