A Performance Analysis of AODV Routing Protocol under Combined Byzantine Attacks in MANETs

Abstract

The concept of byzantine attack comes from Byzantine Generals Problem. In this abstract concept, the loyal byzantine army general are suppose to coordinate in a battlefield to conclude a common plan in the presence of traitor generals which can disrupt such coordination. This Generals Problem resembles the attacks initiated by authenticated nodes/devices in Ad Hoc Network to disrupt the network. Although these attacks can be initiated individually but are more devastating if initiate in a combined way. This paper discusses and highlights the performance degradation of AODV routing protocol, mainly when the byzantine attack are initiated in a combination

A survey of black-hole attack mitigation techniques in MANET: merits, drawbacks, and suitability

“…When there are two or more than two legitimate nodes which collaborate with each other in order to disrupt the communication, they are called as cooperative black-hole attack. The attacks which are launched by the authorized nodes are known as byzantine attacks [7]. In normal AODV routing protocol, whenever the source node wants to communicate with the destination node, it broadcasts route request packet if it does not have a path towards the destination.…”
