A continuous infrastructure-less, self-configured collection of mobile devices connected as a network without wires is termed as mobile ad hoc network (MANET). Dynamic topology, shared physical medium, and distributed operations are some of the characteristics of MANETs due to which they are highly vulnerable to security threats. Black hole attack is a kind of attack that compromises security by redirecting the entire traffic to a node that is not actually present in the network. This paper aims to detect black hole using three detection schemes, i.e., Time-based threshold detection schemes, DRI table with cross checking scheme, and distributed cooperative mechanism. Comparative analyses on all three schemes are done to find out which one detects black hole more accurately. The measurements are taken on the light of packet delivery ratio, throughput, energy consumption and end-to-end delay. Simulation is performed using Network Simulator-2 (NS2). © Springer India 2016.
