A Wireless network is a dynamic network with large no. of nodes. As the traffic increases over the network such type of network suffers from the problems like congestion and packet loss. But in case of Mobile network there is one more problem regarding the life of the network. A network can be affected from some Black hole attack over the network as a result some loss of information occur over the communication. The packet loss is acceptable up to some threshold value but as there is more packet loss the people need some solution for this. The same solution is presented in this paper. Here, the authors are presenting a fuzzy based decision to check a node is infected by Black hole attack or node.
