This Wireless networks are decentralized and the infrastructure less networks, where nodes at any given moment can join or leave the network. Because ad hoc networks are autonomous mobile nodes, they form a temporary network that does not have a fixed infrastructure. Each node in the network is autonomous; therefore, they act as hosts and as routers. Because of this nature of MANET, where any node can join or leave the network without authorization, security is the main challenge in these networks. One of the main security problems of MANET is the attack on the black hole. It happens when a malicious node called a black hole joins the network, during the path discovery process, this node acts as if it had the path to the destination and takes all the packets and does not forward to the desired destination. In this paper, a survey is presented on some of the techniques and methodologies for detecting and preventing black hole attacks in wireless networks and a table representing their advantages and disadvantages.
