Thread-Level Speculation (TLS) is a promising technique that allows the parallel execution of sequential code without relying on a prior, compile-time-dependence analysis. In this work, we introduce the technique, present a taxonomy of TLS...
A novel class of covert channel, out-of-band covert channels, is presented by extending Simmons’ prisoners’ problem. This new class of covert channel is established by surveying the existing covert channel, device-pairing, and...
The increasing demand for traveler clearance at international border crossing points (BCPs) has motivated research for finding more efficient solutions. Automated border control (ABC) is emerging as a solution to enhance the convenience of...
A Survey on Wireless Indoor Localization from the Device Perspective
Jiang Xiao, Zimu Zhou, Youwen Yi, Lionel M. Ni
Article No.: 25
With the marvelous development of wireless techniques and ubiquitous deployment of wireless systems indoors, myriad indoor location-based services (ILBSs) have permeated into numerous aspects of modern life. The most fundamental functionality is...
Survey: Live Migration and Disaster Recovery over Long-Distance Networks
Panagiotis Kokkinos, Dimitris Kalogeras, Anna Levin, Emmanouel Varvarigos
Article No.: 26
We study the virtual machine live migration (LM) and disaster recovery (DR) from a networking perspective, considering long-distance networks, for example, between data centers. These networks are usually constrained by limited available...
Confidentiality-Preserving Publish/Subscribe: A Survey
Emanuel Onica, Pascal Felber, Hugues Mercier, Etienne Rivière
Article No.: 27
Publish/subscribe (pub/sub) is an attractive communication paradigm for large-scale distributed applications running across multiple administrative domains. Pub/sub allows event-based information dissemination based on constraints on the nature of...
Like It or Not: A Survey of Twitter Sentiment Analysis Methods
Anastasia Giachanou, Fabio Crestani
Article No.: 28
Sentiment analysis in Twitter is a field that has recently attracted research interest. Twitter is one of the most popular microblog platforms on which users can publish their thoughts and opinions. Sentiment analysis in Twitter tackles the...
Heap data is potentially unbounded and seemingly arbitrary. Hence, unlike stack and static data, heap data cannot be abstracted in terms of a fixed set of program variables. This makes it an interesting topic of study and there is an abundance of...
Target-tracking algorithms typically organize the network into a logical structure (e.g., tree, cluster, or faces) to enable data fusion and reduce communication costs. These algorithms often predict the target’s future position. In addition...
A Survey of Predictive Modeling on Imbalanced Domains
Paula Branco, Luís Torgo, Rita P. Ribeiro
Article No.: 31
Many real-world data-mining applications involve obtaining predictive models using datasets with strongly imbalanced distributions of the target variable. Frequently, the least-common values of this target variable are associated with events that...
Performance and Security Improvements for Tor: A Survey
Mashael Alsabah, Ian Goldberg
Article No.: 32
Tor [Dingledine et al. 2004] is the most widely used anonymity network today, serving millions of users on a daily basis using a growing number of volunteer-run routers. Since its deployment in 2003, there have been more than three dozen...

Article No.: 33
With almost everything now online, organizations look at the Big Data collected to gain insights for improving their services. In the analytics process, derivation of such insights requires experimenting-with and integrating different analytics...
Knuckle Print Biometrics and Fusion Schemes -- Overview, Challenges, and Solutions
Gaurav Jaswal, Amit Kaul, Ravinder Nath
Article No.: 34
Numerous behavioral or physiological biometric traits, including iris, signature, hand geometry, speech, palm print, face, etc. have been used to discriminate individuals in a number of security applications over the last 30 years. Among these,...
A Survey of Recent Prefetching Techniques for Processor Caches
Article No.: 35
As the trends of process scaling make memory systems an even more crucial bottleneck, the importance of latency hiding techniques such as prefetching grows further. However, naively using prefetching can harm performance and energy efficiency and,...
