We present Ringo, a system for analysis of large graphs. Graphs provide a way to represent and analyze systems of interacting objects (people, proteins, webpages) with edges between the objects denoting interactions (friendships, physical interactions, links). Mining graphs provides valuable insights about individual objects as well as the relationships… (More)
The popularity of smartphones and smartphone applications means that data is the dominant traffic type in current mobile networks. In this paper we present our work on a systematic investigation into facets of the LTE/EPC architecture that impact the performance of TCP as the predominant transport layer protocol used by applications on mobile networks. We… (More)
The PhantomNet facility allows experimenters to combine mobile networking, cloud computing and software-defined networking in a single environment. It is an <i>end-to-end testbed</i>, meaning that it supports experiments not just with mobile end-user devices but also with a cellular core network that can be configured and extended with new technologies.… (More)
In addition to growth of data traffic, mobile networks are bracing for a significant rise in the control-plane signaling. While a complete re-design of the network to overcome inefficiencies may help alleviate the effects of signaling, our goal is to improve the design of the current platform to better manage the signaling. To meet our goal, we combine two… (More)
We present MobiScud, an evolutionary mobile network architecture that integrates cloud and SDN technologies into a standard mobile network in backwards compatible fashion. MobiScud enables personalized virtual machines to seamlessly "follow" mobile network users as they move around.
Modern motor protection relays are capable of long-term failure monitoring and diagnostics based on information collected by a powerful data acquisition system. This includes predicting lifetime of motors. This paper presents an advanced algorithm capable of performing such tasks. It is applicable to different types of rotating electric machines depending… (More)
Engineered protein pores have several potential applications in biotechnology: as sensor elements in stochastic detection and ultrarapid DNA sequencing, as nanoreactors to observe single-molecule chemistry, and in the construction of nano- and micro-devices. One important class of pores contains molecular adapters, which provide internal binding sites for… (More)
We present our work on MOCA, a lightweight Mobile Cloud Offloading Architecture, which uses an in-network cloud platform to provide offloading resources. MOCA integrates with existing mobile network architectures without requiring significant changes, and utilizes software defined networking techniques in the data plane to redirect appropriate traffic to… (More)
We present our Software-defined network Mobile Offloading aRchitecturE (SMORE). SMORE realizes traffic offloading in mobile networks without requiring any changes to the functionality of existing mobile network nodes. At the same time, it is fully aware of mobile network functionality, including mobility.
We investigate the ability of an attacker to passively use an otherwise secure wireless network to detect moving people through walls. We call this attack on privacy of people a "monitoring radio windows" (MRW) attack. We design and implement the MRW attack methodology to reliably detect when a person crosses the link lines between the legitimate… (More)
