In a multi-path wireless network like ad hoc network, co-operation is considered as a significant entity for reliable data dissemination. Since, MANET is highly vulnerable to attack than its wired counterparts. Further, attacks with malicious intent greatly intensify and exploits the vulnerabilities of the network which in turn cripples the performance of MANET. The techniques used possess a low capability of classifying attacks based on the degree of impacts produced by them towards the resilience of the network. For this reason, a need for innovating a set of comprehensive mechanism to prevent the possible attacks of MANET in a flexible way as analogous to the "Detect and response" scheme likes intrusion detection.
