Wireless Ad hoc NETworks (WANETs) are self-arranged networks whose nodes are free to shift randomly while being intelligent to converse with each other not including the help of an existing network infrastructure. Due to its dynamic behavior, one of the main safety problems in ad hoc networks called the black hole attack. It takes place when a fake node referred as black hole connects the network. The black hole node conducts its fake behavior during the process of route discovery. At present, several efficient routing protocols have been proposed for WANET.
