Ad hoc networks are characterized by open medium, dynamic topology, distributed cooperation and constrained capability with more challenges for security. Routing security is the most important factor in the security of the entire network. However, few of current routing protocols have the consideration about the security problems. This paper emphasizes on the black hole attack in the AODV protocol. To provide security in AODV protocol, firstly we have to trace malicious behavior of node. Specially, we analyzed the black hole node behavior and proposed a security system to detect such black hole node in the network and made the secured system that optimizes the loss of packets from such type of attack.
