Analysis of Network Performance Under Attacks Based on Routing Information in MANET

In this paper, an overview of the major attacks against routing information and the defense approaches is given firstly, and all attacks based on routing information is classified into two types: active attacks and selfish attacks. According to the two types of attacks, simulation environment is established in which realize the two attack models based on DSR routing protocol. Then we analyze the effect of network performance under the two attack models. Simulation results show that if there is no misbehavior node in the network, the network performance is improving with the increasing of network stability. If there is misbehavior node, the packet delivery ratio and throughput of network descend apparently. When the percentage of misbehavior nodes becomes 10%, packet delivery ratio and throughput descend sharply. It can degrade by 50% in severe situation.
