Mobile ad hoc networks are wireless, infrastructure less, networks. Due to mobility and limited radio range, every node has to perform the dual responsibility of host of different services as well as routers for forwarding information. Different routing algorithms are used for transmitting the information such as DSDV, DSR, and AODV. These algorithms are designed earlier without taking care of security aspect, so transmitted information and network are vulnerable to different types of attacks. Most popular attack in MANET is black hole attack, which has the severe impact on network.
