Abstract—Mobile Ad hoc Network (MANET) is a collection of wireless mobile nodes that dynamically create a network without a fixed infrastructure. All the characters of MANET make the security problem more serious. The Flooding attacks in the MANET prevents the discovery route process, reduces network througth and increases routing load. In this article, we describe a solution to build Security Mobile Agent (SMA), and integrating SMA into the discovery route process of AODV protocol, improved protocol is called SMA2AODV. Using NS2, we compare the performance of both protocols in the random waypoint and grid network topology under Flooding attacks. Simulation results show that the detection ratio Flooding attacks successfully over 98%, and improved protocol has very reduced the harm of Flooding attacks based on the packet delivery ratio, network throughput and routing load metrics.
