Hubs play important roles in scale-free networks. Existing hub search algorithms mostly assume the availability of the global network structure and use a variety of centrality metrics to search the hubs in the network. However, when it is very difficult to obtain the network topology in large-scale networks, how we can search the hubs? In this paper, a hub search method based on sampling with biased...
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...
