Comprehensive study on MANETs network layer attacks

A Mobile Ad hoc Network (MANET) is a collection of wireless mobile nodes that forms a temporary network in decentralized manner. Security has become a primary concern in order to provide protected communication between mobile nodes in a hostile environment of MANET which poses a number of nontrivial challenges to security design and these challenges clearly make a case of building multifence security solutions that achieve both broad protection and desirable network performance. This paper presents a review on the various network layer attacks, i.e. wormhole attack, blackhole attack and greyhole attack and existing ways to mitigate them.
