MANET is a dynamic network with large number of mobile nodes. As the traffic increases over the MANET it will leads to number of problems i.e. congestion and packet loss. This congestion and packet loss problems occurs due to the attack in MANET. One of attack is black hole attack. As a result some packet loss over the network and slows the communication process. In this paper, the authors are providing the solution against black hole attack which is based on fuzzy rule.
