This paper presents an approach to prevent attacks in MANETs by deploying intrusion detection nodes. Some nodes performing Intrusion Detection Systems, IDS nodes for short, are used to mitigate attacks. Two kinds of attacks, wormhole attacks and black hole attacks are addressed in the paper. The modules used to mitigate wormhole and black hole attacks are called AntiWorm and AntiBlackhole, respectively, in this paper. The IDS nodes are set in sniffing mode in order to estimate the suspicious value of a node within the communication range, according to the routing messages transmitted by the node.
