The operation of MANETs does not depend on preexisting infrastructure or base stations. Network nodes in MANETs are free to move randomly. Therefore, the network topology of a MANET may change rapidly and unpredictably. This paper presents the existing methods to detect misbehavior in MANETs. Routing protocols used in such type of networks generally based on the assumption that, all participating nodes will be fully cooperative. But, due to the open structure node misbehavior may exist and packet loss occurs. Among them one type of misbehavior is that some nodes will take part in routing establishment processes but they do not respond to forward data packets and simply dismiss the packets. The goal of this work is to simulate the 2ACK scheme in ad hoc network. To reduce extra routing overhead, and packet loss, only a few of the received data packets are acknowledged in the 2ACK scheme. It reduces the routing overhead. It has been observed that by using the 2ACK scheme the packet delivery ratio is increased. The results of the 2ACK‐OLSR indicates that it reduces the packet loss and increase the routing overhead.
