- 2. Abstract • In mobile ad hoc networks (MANETs), a primary requirement for the establishment of communication among nodes is that nodes should cooperate with each other. In the presence of malevolent nodes, this requirement may lead to serious security concerns; for instance, such nodes may disrupt the routing process. • In this context, preventing or detecting malicious nodes launching grayhole or collaborative blackhole attacks is a challenge. • This project attempts to resolve this issue by designing a dynamic source routing (DSR)-based routing mechanism, which is referred to as the cooperative bait detection scheme (CBDS), that integrates the advantages of both proactive and reactive defense architectures. • Our CBDS method implements a reverse tracing technique to help in achieving the stated goal. Simulation results are provided, showing that in the presence of malicious-node attacks, the CBDS outperforms the DSR, 2ACK, and best-effort fault-tolerant routing (BFTR) protocols (chosen as benchmarks) in terms of packet delivery ratio and routing overhead (chosen as performance metrics). www.iistechnologies.in Ph: 9952077540
- 3. Existing System • The lack of any infrastructure added with the dynamic topology feature of MANETs make these networks highly vulnerable to routing attacks such as blackhole and grayhole (known as variants of blackhole attacks). • In blackhole attacks, a node transmits a malicious broadcast informing that it has the shortest path to the destination, with the goal of intercepting messages. • In this case, a malicious node (so-called blackhole node) can attract all packets by using forged Route Reply (RREP) packet to falsely claim that “fake” shortest route to the destination and then discard these packets without forwarding them to the destination. • In grayhole attacks, the malicious node is not initially recognized as such since it turns malicious only at a later time, preventing a trust-based security solution from detecting its presence in the network. • It then selectively discards/forwards the data packets when packets go through it. www.iistechnologies.in Ph: 9952077540
- 4. Disadvantages www.iistechnologies.in Ph: 9952077540 • Higher energy consumption • Routing overhead • Increase time delay
- 5. Proposed System www.iistechnologies.in Ph: 9952077540 • In this project, proposes a cooperative bait detection scheme (CBDS) is presented that effectively detects the malicious nodes that attempt to launch grayhole/collaborative blackhole attacks. • In our scheme, the address of an adjacent node is used as bait destination address to bait malicious nodes to send a reply RREP message, and malicious nodes are detected using a reverse tracing technique. • Any detected malicious node is kept in a blackhole list so that all other nodes that participate to the routing of the message are alerted to stop communicating with any node in that list. • Unlike previous works, the merit of CBDS lies in the fact that it integrates the proactive and reactive defense architectures to achieve the aforementioned goal.

- 8. Conclusion www.iistechnologies.in Ph: 9952077540 • In this project, we have proposed a new mechanism (called the CBDS) for detecting malicious nodes in MANET’s under gray/collaborative blackhole attacks. • Our simulation results revealed that the CBDS outperforms the DSR, 2ACK, and BFTR schemes, chosen as benchmark schemes, in terms of routing overhead and packet delivery ratio.
- 9. Future Work www.iistechnologies.in Ph: 9952077540 • Investigate the feasibility of adjusting our CBDS approach to address other types of collaborative attacks on MANETs. • Investigate the integration of the CBDS with other well-known message security schemes in order to construct a comprehensive secure routing framework to protect MANETs against miscreants.
