Impact of black-hole and jellyfish attacks in MANET using HTTP traffic

Abstract

Mobile ad-hoc network (MANET) is an infrastructure less network. This network is a collection of randomly moving mobile nodes. As MANET doesn’t have any centralized management, this network can form anywhere with the participation of randomly moving nodes. Because of such vulnerable behavior of MANET, this network has to face a lot of security problems. There are so many security threats of MANET which doesn’t have any solution. Even detection of those problems is not easy. Some of the security threats are very severe. Those threats can even destroy the whole network. Researchers are working to find out the solution of those threats. Among those threats we have worked with two security threats which are Black-hole attack and Jellyfish attack. Here, we have found out the threats using HTTP traffic. We use OPNET modeler 14.5 as simulator AODV routing protocol. The aim of this thesis is to find out the impact of security threats on MANET using HTTP traffic. We decide the impact using number of events and average number of events utilizing throughput of the OPNET modeler.
