Black hole attack is one kind of routing disturbing attacks and can bring great damage to all clusters of a MANET. Security remains a major challenge for these networks due to their features of open medium, dynamically changing topologies, and infrastructure-less property. As a result, an efficient algorithm to detect black hole attack is important. This paper proposes and evaluates strategies to detecting black hole attacks and build reliable and secure inter cluster routing in wireless ad hoc networks. The authors choose AODV protocol to test their algorithm and ns-3 as their simulation tool.
