Mobile Ad-Hoc Network (MANET) is set of nodes consists of wireless-transmitter and receiver that communicate with each other through two way wireless links .Security is an important issue for MANET due to its unique features such as limited power, open nature, lack of infrastructure so it is necessary to design intrusion detection technique for MANET. Intrusion is defined as kind of unwanted activity happened in network which is affecting the integrity and confidentiality of network. The existing intrusion detection technique like Enhanced Adaptive Acknowledgement Scheme (EAACK) is used to find malicious nodes and based on Digital Signature Algorithm (DSA) and Ron Rivest, Adi Shamir, Leonard Adleman (RSA) asymmetric key cryptography. But RSA takes much longer time for encrypting data and signature size of RSA is large which creates network overhead. In proposed methodology intrusion detection technique is implemented by using Advanced Encryption Standard (AES) and routing through Ad-Hoc On Demand Distance Vector (AODV) protocol. The proposed technique maintains security along with improvement in performance of MANET like PDR and end to end delay. The proposed technique requires less time for encrypt and decrypt the data so it overcomes the problem of EAACK.
