A Review on Black Hole Attack in Mobile Adhoc Network

Mobile ad hoc network is selfconfiguring and infrastructure less network. Due to its dynamic nature, it is more susceptible to severe type of attacks. An assortment of attacks is there to mischief the dexterous working of MANET. One of these attacks is the Black Hole attack which leads to dropping of messages. Attacking node leading agrees to forward packets and then not succeeded to do so. Black Hole attack may take place due to a malicious node which is consciously misbehaving as well as a smashed node interface. In any case, nodes in the network will continuously trying to find a route for the destination, which makes the node consume its battery in addition to losing packets. In this paper we present the literature study of various approaches of Black hole attack propose by researchers in their research. The merits and demerits of the different approaches are also presented.
