Black Hole Attack Detection using Fuzzy Logic

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 we are providing the solution against black hole attack which is based on fuzzy rule. fuzzy rule based solution identify the infected node as well as provide the solution to reduce data loss over network.
