A comprehensive review on wormhole attacks in MANET

As MANETs use wireless medium for communication, these are vulnerable to many security attacks. In this paper a comprehensive review is done on the very recent state of the art research results on wormhole attacks and relevant mitigation measures. 100% of the works reviewed here are published in last five years, out of which 80% are published in last three years. The simulation results in NS2 helps to quantify the comparative performances of the different solutions proposed.
