Black hole attack evaluation for AODV and AOMDV routing protocols

Protecting a mobile ad hoc network (MANET) from malicious attacks is a challenging security issue, many of those attacks are reported on ad hoc on demand distance vector (AODV) and ad hoc on-demand multipath distance vector (AOMDV) routing protocols. Black hole attack (BHA) is a serious attack, in which wireless packets are redirected to a fake mobile node (MN), actually, a fake MN attacks other MNs as it presents itself in such a way that has the shortest path. This paper studies the impact of BHA on the performance of AODV and MAODV in terms of throughput, end-to-end delay and packet delivery ratio using network simulator version 2 (NS-2) and compares the resiliency of these routing protocols against BHAs. Simulation results revealed that AOMDV is more resilient against BHAs as it is able to easily find alternative routes to destination MNs. Copyright © 2018 Inderscience Enterprises Ltd. other. MANETs have no infrastructure and are applicable where wired or infrastructure wireless networks are hard to be accessed, especially in emergency and rescue missions. However, MANETs consume more power, have limited bandwidth routes and their MNs are also behaving as routers in order to establish reliable routes with other MNs.
