Tor is a popular low-latency anonymous communication system. It is, however, currently abused in various ways. Tor exit routers are frequently troubled by administrative and legal complaints. To gain an insight into such abuse, we designed and implemented a novel system, TorWard, for the discovery and the systematic study of malicious traffic over Tor. The system can avoid legal and administrative...

Placement of mesh nodes is an important and challenging issue in the research of wireless mesh networks (WMNs). It is important that the placement occurs after careful network planning, in order to minimize deployment cost while satisfying the requirements of network performance. In this paper, we study the problem of cost-effective node placement (CeNP) in WMNs. First of all, we define the objective...
Wireless mesh networks (WMNs), as a promising technology to provide broadband Internet access, is attracting more and more attention from research community. In the research on WMN design, gateway placement is one of the most important and challenging aspects, that is, finding the optimal number and locations of gateways. Although several gateway placement approaches have been proposed, few of them...
Wireless mesh networks (WMNs) have recently evoked much research attention as a novel technology for last-mile broadband Internet access. When designing a WMN, gateway placement is significant for it determines the total network throughput. To address this problem, a novel gateway placement approach is proposed in this paper, in which three objectives are optimized, i.e. the number of gateways, the...
