Wireless network is the network of mobile computer nodes that are not physically wired. The main advantage of such network is communicating with rest of the world while being mobile. The risks to users of wireless technology have increased as the service has become more popular. Due to the dynamically changing topology, open environment and lack of centralized security infrastructure, a mobile ad hoc network (MANET) is vulnerable to the presence of malicious nodes and to ad hoc routing attacks. There are a wide variety of routing attacks that target the weakness of MANETs. In this paper, we proposed a novel approach for analysis of black-hole and Flooding attack and intended to find methodology. The proposed solution is based on PDR and generating fake request threshold computation by which we can conclude there is availability of malicious attacker. The implementation of the proposed Secure Routing Testing concept of finding malicious attacker is performed using NS 2 i.e. network simulator 2 and  for implementing the security protocol in existing routing the AODV routing protocol with modifications are performed. The experimental results shows the adoptable performance of the algorithm and improves the different performance parameters i.e. throughput, end to end delay, packet delivery ratio, and energy consumption.
