Mobile ad hoc networks (MANETs) are infrastructure less networks which consist of dynamic collection of nodes with rapidly changing topologies of wireless links. MANETS are mobile and therefore, they use wireless connections to connect to various networks. Devices in range can communicate in a point-to-point fashion. MANETs are liable to different types of DoS attacks in which packets are dropped. Black hole attack is an event that degrades the performance of the network. This paper discusses the effects of the malicious attacks and the comparison of AODV Routing Protocol with the Revised AODV Routing Protocol in the presence of the Black hole attack based on performance metrics.
