Peer-to-peer video delivery (P2PTV) is still one of popular applications to enjoy video streaming service. To grasp and understand P2PTV traffic characteristics, a two-stage unit traffic clustering method has been proposed. In this paper, we verify the efficiency and generality of the proposed method through classifying mixed traffic data sets gene...

In ad hoc networks, backoff-based opportunistic routing enables flexible forwarder selection based on a random backoff time. However, it assumes to require symmetry of each link due to the use of reverse path information. In this letter, we verify an asymmetric link problem based on their behavior and propose a solution to this problem. The propose...

We now use the Internet of things (IoT) in our everyday lives. The novel IoT devices collect cyber–physical data and provide information on the environment. Hence, IoT traffic will count for a major part of Internet traffic; however, its impact on the network is still widely unknown. IoT devices are prone to cyberattacks because of constrained reso...

Named Data Networking (NDN) has emerged as a future networking architecture having the potential to replace the Internet. In order to do so, NDN needs to cope with inherent problems of the Internet such as attacks that cause information leakage from an enterprise. Since NDN has not yet been deployed on a large scale, it is currently unknown how suc...

Internet usage has shifted from host-centric end-to-end communication to a content-centric approach mainly used for content delivery. Information Centric Networking (ICN) was proposed as a promising novel content delivery architecture. ICN includes in-network caching features at every node which has a major impact on content retrieval. For instance...

Named-Data Networking architecture relies on cache networks, where nodes store the data for further requests. However, the memory needed at each node called Content Store represents the most significant part of the entire cost of the infrastructure that has to be supported by network providers, making difficult the change from the current Internet...

Content delivery such as P2P or video streaming generates the main part of the Internet traffic and Content Centric Network (CCN) appears as an appropriate architecture to satisfy the user needs. However, the lack of scalable routing scheme is one of the main obstacles that slows down a large deployment of CCN at an Internet-scale. In this paper we...

Online Social Networking (OSN) has become one of the main applications on the Internet. Pinterest is an emerging social network that is gaining a lot of popularity and mostly focuses on images. In this work, we crawled during several months the Pinterest website and collected all the relevant information to characterize this social network (e.g., u...

The Online Social Networks (OSN) have become an important trend in current networks. Due to the susceptible nature of the private data available in OSN, the acquisition of data sets is not an easy task. In this paper and based on the state of the art of measurement studies, we present SONETOR, a synthetic social network traffic generator, character...

Content Centric Networking (CCN) emerged as a replacement architecture for the current Internet. CCN resorts to in-network caching to enhance end-user delivery performance. At the same time, Online Social Networks (OSN) have become the common paradigm to exchange information between users. OSNs carry extremely valuable information about their users...

Nowadays cities invest more in their public services, and particularly digital ones, to improve their resident's quality of life and attract more people. Thus, new crowdsourcing services appear and they are based on contributions made by mobile users equipped with smartphones. For example, the respect of the traffic code is essential to ensure citi...

Content Centric Networking is a promising architecture for the Future Internet to deliver content at large-scale. It relies on named data and caching features which consists of storing content across the delivery path to serve forthcoming requests. As some content is more likely to be requested than other, caching only popular content may help to m...

Content Centric Networking (CCN) has recently emerged as a promising architecture to deliver content at large-scale. It is based on named-data where a packet address names content and not its location. Then, the premise is to cache content on the network nodes along the delivery path. An important feature for CCN is therefore to manage the cache of...
