Magnetic resonance wireless power transfer (WPT) in the marine environment can be employed in the charging system for underwater vehicles. Seawater submersion of a WPT system results in additional energy loss through eddy current generation. In this paper, by equating the input power to the summation of power delivered to the load, consumed by transmitter and receiver coil resistances, and consumed...
Many IP Geolocation services and applications assume that all IP addresses within the same /24 IPv4 prefix (a /24 block) reside in close physical proximity. For blocks that contain addresses in very different locations (such as blocks identifying network backbones), this assumption can result in a large geolocation error. In this paper we evaluate the co-location assumption. We first develop and validate...
Bot detection methods that rely on deep packet inspection (DPI) can be foiled by encryption. Encryption, however, increases entropy. This paper investigates whether adding high-entropy detectors to an existing bot detection tool that uses DPI can restore some of the bot visibility. We present two high-entropy classifiers, and use one of them to enhance BotHunter. Our results show that while BotHunter...
This paper proposes an IP trace analysis system based on code moving (IP_TASCM) for sharing Internet measurement, tools and dataset. However, two characteristics differentiate it from other prior similar systems. One of them is that besides the common catalog service, IP_TASCM also stores tools, datasets and measurement results together for researchespsila download and analysis. The other one is that...
Aggregate flow is the base methodology of network measurement and the orientation of next generation network management. For the same data, different flow specifications lead to different results, and the costs also vary significantly. To analyze the correlations among specifications, we select seven wide used specifications and calculate their single disparity degree and comprehensive similarity...
