MANET (Mobile Ad-hoc Network) is simply a set of mobile hosts connected wirelessly without any centralized management, where each node acts as a packet sender, packet receiver, and a router at the same time. According to the nature of this network, the dynamic topology and the absence of a centralized management cause several security issues and attacks, such as the black hole attack, the wormhole attack, and the impersonation and repudiation attack. In this survey, we are going to introduce the Black Hole attack security issues and some of the detection techniques used to detect the black hole attack. In this kind of attack (black hole attack) the intruders manipulate the normal behavior of the network, by introducing themselves as the node with the shortest path to the destination. Intruders can do a malicious behavior over the network. The black hole problem is one of the security attacks that occur in mobile ad hoc networks (MANETs). We present two possible solutions. The first is to find more than one route to the destination. The second is to exploit the packet sequence number included in any packet header. Computer simulation shows that compared to the original ad hoc on-demand distance vector (AODV) routing scheme, the second solution can verify 75% to 98% of the route to the destination depending on the pause times at a minimum cost of the delay in the networks.
