The Mobile ad-hoc network (MANET) is a self-design infra-structure less networks of mobile nodes. Each node in a network acts as a router and can travel on any route in a network. And it also have constantly changing topology. There are various types of attack in Manet which reduce the performance of network. One of them is flooding attack which occurs when a network is heavily loaded with traffic which includes the route request packet for connection. Flooding is the reason for traffic and congestion in the network and also the incompleteness of legal connection. In this paper the detection of flooding attack is done by analyzing the behavior of nodes so that the legal connection can be established. By these analyses the efficiency of the system increases and resource utilization is done properly.
