In this paper we present a novel prospective of virtual private networks built upon the fourth generation smallcell technology. The proposed solution promotes the enterprise manageability on its private connections, users' mobility, and QoS provisioning,...

Cognitive Networks have been proposed to opportunistically discover and exploit licensed spectrum bands, in which the secondary users' (SU) activity is subordinated to primary users (PU). Depending on the nature of interaction between the SU and PU, ...

This work explores and advocates the use of automatic generation of local schedulers, with an application to the design of Wireless Sensors Networks (WSN). The contribution presented is a design method relying on formal tools, as well as a solution to ...

One of the applications as a source of big data, there is a sensor network for--the environmental monitoring that is designed to detect the deterioration of the infrastructure, erosion control and so on. The specific targets are bridges, buildings, ...

In this study we present an approach to tackle publish-subscribe communication patterns in large scale networks without the use of broker nodes. To that end publisher/ subscriber information disseminates through paths constructed using a path-building ...

Routing in Delay Tolerant Networks (DTN) requires nodes to work in a cooperative way. Due to the selfishness nature, the nodes are not willing to use their energy to help others. But two nodes with some relations (friends) are more willing to help each ...

High throughput wireless access networks based on IEEE 802.11ac support a number of protocol enhancements at the physical and medium access control sublayer for supporting data rates in the order of Gigabits per second. These include multiple antenna ...

In traditional sensor networks, data processing is mostly simple and even negligible in terms of energy consumption. On the opposite, in Wireless Multimedia Sensor Networks (WMSNs) the captured data is usually voluminous and requires local processing. ...

With increasing mobile usage and more demands for higher-speed data, shortage of spectrum is seen as becoming in a limiting factor in growth of new services and traffic volume. Regulators, such as the FCC and Ofcom, have been considering how to improve ...

A wireless sensor network (WSN) consists of a group of energy-constrained sensor nodes with the ability of both sensing and communication, which can be deployed in a field of interesting (FoI) for detecting or monitoring some special events and then ...

In the context of aging populations, maintaining persons at home represents one of the solutions seriously considered. In France, one person among three will be over 60 years in 2050, against one among five in 2005. Many works have investigated the ...

In the last decade, the world has witnessed the popularization of wireless local area networks (WLANs) through the use of the WiFi (Wireless Fidelity) technology, with an estimated 6.5 million public hotspots available in 2013 and the number expected to ...

Nowadays, the Wi-Fi Direct technology is supported by most of smartphones on the market, and provides a viable solution to guarantee opportunistic communication among group of devices in a 1-hop range. However, the current specifications of the standard ...

The fourth generation of mobile networks, known as Long Term Evolution (LTE), is the first 3GPP cellular fully-IP standard. Quality of Service (QoS) policies are based on bearers and QoS Class Identifier (QCI). Here we focus on Quality of Experience (...

We propose a system, Wideband-Fi, that is motivated by the information theoretic optimality of impulsive frequency shift keying (I-FSK) in wideband systems, and by the availability of orthogonal frequencies in current Wi-Fi systems. Using orthogonal ...

Technology coined as the vehicular ad hoc network (VANET) is harmonizing with Intelligent Transportation System (ITS) and Intelligent Traffic System (ITF). An application scenario of VANET is the military communication where vehicles move as a convoy on ...

Vehicular networks are networks comprised of vehicles traveling cities and highways. During their trajectories, these vehicles interact with other vehicles and roadside units, to make safer and enjoyable traffic. Several factors may influence these ...

Vehicle Internet access benefits from using heterogeneous multi-provider networks. However, such access suffers significantly from insufficient handover processes. Due to high vehicle speeds, handover happens frequently and is substantially impaired by ...

In this paper, we study the sensor localization problem using a drone. Our goal is to localize each sensor in the deployment area ensuring a predefined localization precision, i.e., a bound on the position error, whatever is the drone's altitude. We ...

This work extends the state of the art in the modeling of the lifetime of a sensor network. This is performed concentrating on the peculiarities exhibited by a specific, but realistic scenario, surveillance sensor networks, sensor networks in charge of ...

In this paper, we propose a statistical framework to systematically evaluate the fairness offered by different LTE (Long Term Evaluation) technologies when they coexist with Wi-Fi in unlicensed band. In particular, we study the coexistence performance ...

Multicast/Broadcast Multicast Service over Single Frequency Network (MBSFN) technology has introduced advanced broadcast capabilities to cellular systems. In Long Term Evolution Advanced (LTE-A) systems, MBSFN transmission accommodates multicast groups ...

With the myriad of information resources available on the Web, personalization has become important to facilitate information retrieval and recommender systems that provide information and services adapted to the user's needs. A crucial component in any ...
