Simulation and analysis of distributed low-rate denial-of-service attacks

Low-rate denial-of-service attack is a novel category of DDoS attacks. The paper defines defense performance as metric to analyze whether the degree of distribution of attack sources impacts the LDoS attack greatly. From the result of simulation on NS2, the deeper degree of distributed, the better defense performance of Droptail (passive queue management), and the worse defense performance of RED (active queue management). And we also analyze the factors which may have impacts on the attack.
