Host mobility has been a long standing challenge in the current Internet architecture. Huge proportions of traffic are now attributed to mobile devices [1]; however, despite this prominence, mobility often remains a badly handled concept. Some have recently argued that the main reason for this lies in its choice of what to name [2]. The Internet Protocol(More)
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)
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)
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)
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)
In this paper we propose a new protocol for unstructured 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)
Content distribution services are booming and they will be responsible for the majority of future Internet traffic. In parallel, Online Social Networks (OSNs) have become today’s most popular Internet applications. The widespread adoption of OSNs has drastically changed the way content is consumed in the Internet, as the popularity of a given content is(More)

On-line Social Networks (OSNs) are being used intensively by countless professional players (e.g., large companies, politicians, athletes, celebrities, etc.) as a means of interacting with a huge amount of regular OSN users. This has led to an increasing research interest that aims at understanding what are the strategies of professional users in OSNs. In(More)
