Abstract : MANET networks are defined as the wireless self configuring networks that are capable of operating without the support of any fixed infrastructure and a central coordinator which makes the routing a complicated task. One of the main challenges in MANET is to design the robust security solution that can protect MANET from various routing attacks. MANET is vulnerable to different types of attacks such as blackhole, sybill attack, wormhole attack, grayhole attack and so on. Among them black hole is one the major attack which effects the entire network performance based on routing, packet delivery ratio, throughput and end to end delay of packets. The communication takes place between two nodes by sharing their information like from node to nexthop nodes information. In this paper an Adaptive method algorithm for detection and prevention of blackhole attack in a MANETs is proposed based on Data Access Table (DAT) which is an array [ ] [ ] maintains from node to nexthops node information. We choose AODV as routing protocol and NS2 as simulation tool. The results are compared with threshold based algorithm for detection and prevention of cooperative blackhole attack in a MANET. The results show that Adaptive method gives better performance than compared to threshold based algorithm, in terms of throughput, packet delivery ratio.
