Increase the performance and enhancing Secure Authenticated Multipath Encrypted Protocol in MANET

Multipath routing in adhoc networks increases the resiliency against security attacks of collaborating malicious nodes, by maximizing the number of nodes that an adversary must compromise in order to take control of the communication. The multipath routing along with SDMP and WEP to allow the receiver to reconstitute the original message in the correct order. So fault tolerance problem can also use diversity coding technique which is based on information redundancy. Even if an attacker succeeds to obtain one part or more of the transmitted message. The probability of reconstructing the message is high. We propose a new protocol called SAMEP (Secure Authenticated Multipath Encrypted Protocol) is used to transmit the authenticated and encrypted messages, which provides highly secure multipath routing mechanism in adhoc network. The results are analyzed and depicted graphically.
