MANET stands for Mobile Ad-hoc NETwork. The ad hoc network that is used for mobile communication is called MANET. The MANETS are used when the user is moving. Because MANET does not depends on fixed infrastructure. Wireless networks are used to connect with different networks in MANETs. Security is more critical in wireless communication when compared to the wired communication. So the security of the MANET must be optimized to secure information while transferring. The proposed system introduces a new intrusion-detection system named Competent Enhanced Adaptive ACKnowledgment (CEAACK) for finding malicious nodes using RSA digital signature and EAACK specially designed for MANETs.
