Lokare Sinhgad Institute of T e c hnology , Lonavala, Pune A.M Kanthe Faculty of Electrical Engineering and Computing, University of Zagreb, Croatia Dina Simunic Faculty of Electrical Engineering and Computing, University of Zagreb, Croatia ABSTRACT A MANET (Mobile Ad - hoc Network) is a network of mobile devices in a self - configuring and infrastructure less environment. The devices in MANET are linked by wireless medium. There are big chances of attacks in MANET due to its natural features including dynamically changing network topology, open medium, no centralized monitoring and management point. There is no assurance of attack free communication. The malicious n ode(s) causes dropping and forwarding only selective packets are called as gray hole. So, the security solution must be developed to address the protection of data and route. In this paper we attempted to mitigate the gray hole attack and proposes a credit based approach based on Ad - hoc On Demand Distance Vector (AODV) routing protocol. In the proposed and implemented method, we used credit value measurement for the detection of cooperative gray hole attack. This paper shows the technique which is capable o f finding chains of cooperating gray hole nodes which drop a major part of communication. The paper shows the result based on varying density, pause time and mobility
