Mobile Ad hoc NETworks (MANETs) are self-configuring, decentralized networks in which the nodes communicate without the need of infrastructure. The nodes work in an environment in which mutual trust between the nodes form an important part of the communication. This property of the network is exploited to launch a blackhole attack. Blackhole attack is a network layer denial of service attack in which an adversary node attracts the data traffic towards itself by advertising a short route to the destination and instead of forwarding, it simply drops the packets.
