Gray hole attacks are regarded as a kind of black hole attacks which are produced by malicious nodes in ad hoc networks. These attacks are produced as a result of extensive advertisements in response to path requests made on the part of the source node in a network. Indeed, malicious nodes deceive normal nodes of the network and announce that they possess the shortest path for reaching the destination. Hence, normal nodes register the malicious nodes as new members in the transmission and reception process; however, malicious nodes suddenly show negative behaviors and they remove a significant amount of the reached packets. Many research studies have been done to preventthis type of attacks in ad hoc networks and some findings have beenobtained in this regard. The purpose of the present study was to propose a method so as to optimize and maintain protocols which transmit and receive data in wireless networks. In this study, through the collaboration of legal nodes, a method was proposed which was intended to detect and isolate gray hole attacks in the network. NS2 simulator was used to simulate and check the validity of the proposed method.
