Traditionally, DNS traces from several local DNS servers are used passively to measure the DNS query behavior. However, since botnets are a wide-scale threat and usually reside in geographically dispersed networks, the vantage point of several local DNS servers is sometimes too small to help us understand the DNS query behavior (e.g., whether queried or not, average query rate) of botnets. In this paper, we actively measure the DNS query behavior of botnets in geographically dispersed networks via the DNS cache probing technique. We first analytically characterize how multiple domain names are queried by botnets in different networks under certain circumstances. Then, we actively measure real botnet samples in the wild to gain insight into how multiple domain names are queried by botnets in 480 geographically dispersed networks globally, and show that our analytical characterization well describes the DNS query behavior of the botnet samples. The active measurement technique can help to acquire extensive DNS query information in different networks and thus potentially facilitate various DNS-related research and applications.","PeriodicalId":72021,"journal":{"name":"...

This paper investigates the problem of the relay selection and resource allocation in a downlink OFDMA cognitive relay network. The objective of this optimization problem is to maximize both system throughput and system fairness, which is achieved through our proposed non-transferable utility coalition graph game algorithm (NTU-CGGA). In this algorithm, the SUs with more available channels can help SUs with less available channels to improve their utility in terms of the throughput and fairness by forming a directed tree graph. The coalition graph is formatted according to spectrum availability and traffic demands of SUs by using merge-split rule. So it can effectively exploit both space and frequency diversity of the system. Simulation results show that, NTU-CGGA significantly improves system throughput while not reducing the fairness level, which has a better performance comparing with other existing algorithms.","PeriodicalId":72021,"journal":{"name":"...
