This paper presents a detail description of novel approach for collaborative attacks in Mobile Ad hoc Networks(MANETs). Providing secure communication is one of important aspects In Mobile Ad hoc Networks (MANETs). Routingprotocols helps to transfer the packets from source to destination. Routing Protocols are vulnerable to collaborative blackhole attacks. When malicious nodes work together to drop the packets called collaborative attacks, i.e. Blackhole attackscompletely drops the packets in MANETs. We propose a Cooperative Bait detection (CBDS) mechanism for preventcollaborative black hole attacks in MANETs. In this scheme integrates features of Dynamic Source Routing (DSR) and 2ACKprotocols. CBDS scheme merges the advantage of both proactive and reactive defense architecture and provide secure datatransmission using key distribution center (KDC). In the initial stage it uses Bait id concept to detect malicious node in thenetwork using proactive architecture, and it switches to reactive defense strategy. The scheme involves three steps, the baitstep, suspected path detection and the Confirmation Request. The bait step attracts the malicious node and next step detectsuspected path. The last step involves the confirmation of the given path is secure for the destination request from itsneighbor. To secure data transmission we use RSA decryption and encryption algorithm scheme. The CBDS outperforms theDSR, 2ACK, and best-effort fault-tolerant routing (BFTR) protocols chosen as benchmarks in terms of packet delivery ratioand routing overhead chosen as performance metrics.
