Abstract: Mobile Ad hoc Networks also called infrastructure less networks are complex distributed systems consist of wireless links between the nodes and each node also works as a router to forwards the data on behalf of other nodes, MANETs have been widely used for various important applications such as military crisis operations and emergency preparedness and response operations. The dynamic topology feature of MANETs makes these networks highly vulnerable to various attacks. We propose a detection scheme called the cooperative bait detection scheme, which aims at detect and prevent malicious nodes launching black and gray hole attacks in MANETs. By using CBDS its only prevent the black-hole attack, There is no possibilities to detect and prevent the gray-hole attack. So, The Packet Estimation Algorithm to Calculate packet delivery rate per hop count determine trustworthiness, To prevent both the attacks in the wireless communication. Main Advantages are preventing (or) avoiding an attack in its initial stage, Hidden attack is not possible and Qos is maintained.
Keywords: CBDS, Packet estimation, RREQ, RREP.
