摘要：MANET is self-configuring infrastructureless wireless network. It means that any node can enter in the network at any time and can left the network at any time. In MANET, for packet delivery, each node has to communicate with other node to establish a route and each node has to maintain a Routing table which provides a fresh route from source node to destination node. MANET faces a flooding attack whose purpose is to drain off scarce resources in other MANET node such as battery power and routing table by flooding a specific node with RREQ messages or false routing information. This prevents registration of any new route in t he routing table of victim node. To avoid this problem we need to focus on secure access of route request(RREQ) and route response(RRES) from node to node. In our approach, we are using node-to-node authentication using challenge-response protocol and hash function) framework in which one authenticated node can respond to route request from other authenticated node only. Also, we are using Malicious_Node_Table (MNT) which stores information about malicious nodes present in network. For packet forwarding from source node to destination node, AODV routing protocol will be used . The goal of this approach is to provide node availability and better security for packet delivery in MANET. This paper describes proposed work of our approach to prevent flooding att ack in MANET
