ABSTRACT: Mobile Ad hoc Network (MANET) is a collection of mobile hosts with wireless interfaces that form a temporary network without the aid of any fixed infrastructure or centralized administration. A MANET is a type of ad hoc network that can change locations and configure itself on the fly. The dynamic and cooperative behaviour of ad hoc networking without any centralized or unified controlling authority for authentication and monitoring is sensitive to attacks that damage or exploit the cooperative behaviour of ad hoc routing. Routing attacks lead to the most disastrous damage in MANET. The main objective of this paper is to enhance the security against routing attacks in MANETs. Intrusion detection based on DAHT (Dual Authentication Hash Technique) entirely depends on the end to end communication between the source and destination is employed here. The proposed technique identifies the misbehaving nature of current node and the previous node where it receives the information. DAHT is simulated with various parameters in NS2. The results obtained are compared with existing mechanism. The results show that malicious detection, overhead reduction and delay are better when compared to the existing system that is employed in protecting the routing information.
