In this study, the network was simulated in NS-3 simulator in a normal mode, black-hole mode and prevention mode. All packets were dropped in black-hole mode and last nodes were removed from the network. The effects were recorded pertaining packets transmitting successfully with some added delay and slightly more energy consumption than in the normal mode. A concept for detection and prevention of black-hole attack is presented with the help of transmitting fake RREQ packet that has non-existing destination which cheats black-hole node to response while normal nodes just bypass by broadcasting to neighbor nodes. The effect of multiple black-hole nodes in the network showed detection time increasing with the increased number of black-hole nodes which depend on the position of the black-hole node substrate.
