A Secure Cooperative Bait Detection Approach for Detecting and Preventing Black Hole Attacks In MANETS Using CBDS

In MANET, a major necessity to distribute the communication between nodes is that each node should work along with each other. This communication could face many obstacles created by adversary resulting in disconnection. To overcome this problem a new mechanism based on dynamic source routing (DSR) which could be mentioned as cooperative bait detection scheme (CBDS). It merges the favors of both proactive and reactive protection phenomena. This method performs a reverse tracing technique which aids in accomplishing the desire. As a result CBDS perform better than the existing method which includes the DSR and 2ACK protocols with regard to packet delivery ratio and routing overhead. As an extension work, we propose an authentication scheme based on elliptic curve cryptograph (ECC). With this it is possible to enable intermediate nodes authentication.
