Exposure and Avoidance Mechanism of Black Hole and Jamming Attack in Mobile Ad hoc Network

Mobile ad hoc network (MANETs) is an infrastructureless/self-configurable system in which every node carries on as host or router and every node can participate in the transmission of packets. Because of its dynamic behaviour such system is more susceptible against various sorts of security threats, for example, Black hole, Wormhole , Jamming , Sybil, Byzantine attack and so on which may block the transmission of the system. Black hole attack and Jamming attack is one of them which promote itself has shortest or new fresh route to the destination while jamming attack which make activity over the system. This paper introduces the thorough literature study for the Black hole attack and jamming attack of both the attack by various writers.
