Evaluation of MANET Routing Protocols under Black Hole Attack Using AODV and OLSR in NS3

Abstract

Mobile ad hoc network (MANET) is a temporary network used in any application where the deployment of a wired network infrastructure is too restrictive. MANET is consists of wireless mobile nodes without any infrastructure and it has no centralized administration and no centralized equipment like access points. Each node in MANET need specifics routing protocols to adapt mobile environment that characterized by changing network topology dynamically and should be efficient in energy and bandwidth. These routing protocols are affected by the threat of malicious nodes attacks on MANET.In this paper, we analyzed two important routing protocols under Black Hole attack, On Demand Distance Vector (AODV) as a reactive protocol and optimized Link State Routing protocols (OLSR) as a proactive protocol. To evaluate the impact of the Black hole attack on routing protocol performance we used four metrics to compare, on the basis of Throughput, Packet Delivery Ratio (PDR), End-to-End Delay (EED) and Packet Lost to validate which protocol is more vulnerable to Black Hole attack all measurements were carried on Simulating in Network Simulation Tool (NS3).
