A Mobile Ad hoc NETwork (MANET) is a group of self-organized wireless mobile nodes (MNs) able to communicate with each other without the need of any fixed network infrastructure nor centralized administrative support. Furthermore, the transmission range in such mobile devices is limited; thus, a packet is forwarded in a multihop path relying on the nodes in the routing path. Due to that, MANETs need the cooperation of every node in the path to achieve a successful packet delivery. However, depending on the MANET application, nodes are willing to cooperate with each other (e.g., rescuing services) since they are controlled by an authority, or might be reluctant to cooperate (e.g., data sharing [ 1 ], traffic monitoring [ 2 ], emergency assistance services [ 3 , 4 ], and multimedia data transmission [ 5 ]) trying to save their own resources. Since MANET nodes usually have limited power (i.e., battery) and scarce computational resources (CPUs), nodes might refuse to cooperate in order to save their limited resources. This misbehavior of nodes would drastically affect the routing protocol operation.
