| dc.description.abstract | Ad hoc networks are showing wider acceptance in the future trend of wireless system. It became clear that group-oriented communication is one of the key application classes in Mobile Ad Hoc Network environments, where several multi cast routing protocols are proposed. These routing protocols assume non adversarial environment and do not take security issues into account in their design The demand put on the wireless system is challenging the current design of secured system. Mobile ad hoc networks are prone to security attack than other networks due to its unique characteristics. Research works are going on which help protect ad hoc networks from malicious node behaviors, the demand put on security mechanisms is a challenge due its bandwidth and energy requirements. This study considered to model attack in the simulator for varied properties of multicast communication and performed analysis We arranged simulation set up to show increase in group communication size by increasing number of receiver nodes decreases the impact of attacker nodes. The effect of attacker node position being near sender and near receive is also analyzed where being near sender more serious than near receiver In this thesis we thoroughly analyzed the performance of multi cast routing protocol under security attack. We incorporated black hole and jelly fish attacks in Protocol for Unified Multicasting through Announcements by modifying its source code. The design is tested on Network Simulator NS-2. Simulation results show that the presence of attacker node has serious effect on the performance protocol, where analysis showed the packet delivery fraction, good put and end to end delay were affected, the more the number of attacker nodes , the more impact of attack Keywords Mobile Ad Hoc Network, Security Attack, Multicast Routing | en_US |
