In essence, an information-centric network (ICN) is one which supports a content request/reply model. One proposed benefit of this is improved mobility. This can refer to provider, consumer or content <i>mobility</i>. Despite this, little specific research has looked into the effectiveness of ICN in this regard. This paper presents a survey of some of the(More)
—BitTorrent is the most successful peer-to-peer application. In the last years the research community has studied the BitTorrent ecosystem by collecting data from real BitTorrent swarms using different measurement techniques. In this paper we present the first survey of these techniques that constitutes a first step in the design of future measurement(More)
In this paper, we conduct a detailed measurement study to characterize and compare the " group-level " behavior of users in Facebook, Twitter and Google+. We focus on Popular, Cross (with account in three OSNs) and Random group of users in each OSN since they offer complementary views. We capture user behavior with the following metrics: user connectivity,(More)
The ICT (Information and Communication Technology) sector has recently been identified as a growing contributor to worldwide greenhouse gases emissions and power consumption. This has triggered interest for more energy efficient ways to design and operate telecommunication networks. We present an overview of the solutions proposed within the European(More)
Peer-to-peer systems have recently emerged as an attractive alternative to client/server approaches, especially in the area of content distribution. By efficiently leveraging the available upload bandwidth of the end users, BitTorrent becomes a de facto standard for scalable content distribution. Inspired by its success, many companies try to shift the(More)
We present OnMove, a protocol for content distribution in wireless delay tolerant networks for use by handheld devices. To improve content distribution, OnMove exploits social characteristics (social similarities and physical encounters) between individuals. We motivate the problem and describe a content sharing protocol based on a ranking algorithm that(More)
—In this paper, we examine the effect of overlay structure in live peer-to-peer (P2P) streaming applications, on the inter-AS traffic. We identify a collection of edge ASes whose clients are likely to participate in P2P streaming applications. We derive the AS-level path between all pairs of selected edge ASes by simulating BGP routing over a snapshot of(More)
— In this paper we propose a new protocol for uns-tructured and semantic-searching based p2p networks: Bittella. It forms a three level overlay network: the lowest level is the unstructured p2p network (e.g. Gnutella). The medium level is formed by clusters per content, we call the resulting structure Small World per Content structure. This level allows the(More)
This paper characterizes the propagation of the information in one of the major OSNs, Google+ (G+). It extends previous works, which study information dissemination in other OSNs, based on two main contributions: (i) it is the first work that takes into account all publicly available information in a major OSN to perform such characterization rather than(More)
