We consider a scenario where an Internet Service Provider (ISP) serves users that choose digital content among M Content Providers (CP). In the status quo, [...]

Bootstrap percolation is a well-known activation process in a graph,in which a node becomes active when it has at least $r$ active neighbors.Such process, originally [...]

Abstract: The Web is the largest public big data repository that humankind hascreated. In this overwhelming data ocean, we need to be aware of thequality [...]

Network Function Virtualization (NFV) is an emerging approach that has received attention from both academia and industry as a way to improve flexibility, efficiency, and [...]

In-network caching is an appealing solution to cope with the increasing bandwidth demand of video, audio and data transfer over the Internet. Nonetheless, an increasing [...]

The future of social networking is in the mobile world. Future network services are expected to center around human activity and behavior. Wireless networks (including [...]

In this talk we will deal with problems arising in device-to-device (D2D) wireless networks, where user devices also have the ability to cache content. In [...]

Ubiquitous smart technologies gradually transform modern homes into Intranet of Things, where a multitude of connected devices allow for novel home automation services (e.g., energy [...]

We consider the problem of accurately estimating the reliability of workers based on noisy labels they provide, which is a fundamental question in crowdsourcing. We [...]

Abstract: Many of the most costly security compromises that enterprises suffer manifest as tiny trickles of behavior hidden within an ocean of other site activity. [...]

We consider a network of multi-server queues wherein each job can be processed in parallel by any subset of servers within a pre-defined set that [...]

Use of anycast IP addresses has increased in the last few years: once relegated to DNS root and top-level domain servers, anycast is now commonly [...]

Abstract: In the “big data” era, data is often dirty in nature because of several reasons, such as typos, missing values, and duplicates. The intrinsic [...]

I present our ACM UIST'15 Best Paper Award-winning research on Webstrates: Shareable Dynamic Media. In this work, we revisit Alan Kay's early vision of dynamic [...]

Resources such as Web pages or videos that are published in the Internet are referred to by their Uniform Resource Locator (URL). If a user [...]

Abstract: Cloud-Radio Access Network (C-RAN) is a new emerging technology that holds alluring promises for Mobile network operators regarding capital and operation cost savings. However, [...]
