Abstract: Mobile ad hoc networks (MANET) are widely used in places where there is little or no infrastructure. A number of people with mobile devices may connect together to form a large group. Later on they may split into smaller groups. This dynamically changing network topology of MANETs makes it vulnerable for a wide range of attack. In this paper we propose a complete protocol for detection & removal of networking Black/Gray Holes by using OPNET network simulator 14.5; it is the latest version of simulation software. Basically, OPNET allows you to build a network with a range of simulated “reallife” equipment, so different configuration options can be tested. And considering two different networks with 15nodes and 35 nodes in network and evaluating a security attack against MANET as a network, different statistics or performance metrics Packet loss, Packet delivery ratio and Average end to end delay has been used.
