Mobile Ad-hoc Networks (MANETs) allow mobile hosts to initiate communications with each other over a network without an established infrastructure or a central network authority. Because of this, MANETs have dynamic topologies because nodes can easily join or leave the network at any time. From a security design perspective, MANETs are vulnerable to various types of malicious attacks. As are result, Ad-hoc On-demand Distance Vector (AODV), which is one of the standard MANET protocols, can be attacked by malicious nodes. A black hole attack is one type of malicious attack that can be easily employed against data routing in MANETs. A black hole node replies to route requests rapidly with the shortest path and the highest destination sequence number. The black hole node does not have an active route to a specified destination associated with it and it drops all of the data packets that it receives. In this paper we have discussed some basic MANET routing protocols like Ad-hoc On Demand distance Vector (AODV), Dynamic Source routing (DSR), Optimized Link state Routing (OLSR). Main objective of this paper is to address some basic security concerns in MANET, operations of malicious node and its effect on these routing protocols.
