Mobile Ad-hoc NETworks (MANETs) technology has gain popularity in recent years by researchers on account of its flexibility, low cost and ease of development. Hence ad hoc networks needs very specialized security methods. But there is no single approach fitting all the networks, as the nodes can be any devices. MANETs are much more vulnerable to attack than the wired network. The black hole attack is a type of denial-of-service attack which passed out disrupts the service of network layer. A Fuzzy Inference System (FIS) is implemented to be Matlab 7.0 and the model is found to be satisfactory with the fuzzy input metrics and de-fuzzified output metrics.
