1. Multi-Step-Ahead Spectrum Prediction for Cognitive Radio in Fading Scenarios
Abstract This paper analyzes multi-step-ahead spectrum prediction for Cognitive Radio (CR) systems using several future states. A slot-based scenario is used, and prediction is based on the Support Vector Machine (SVM) algorithm. The aim is to determine whether multi-step-ahead spectrum prediction has gains in terms of reduced channel-switching and increased

2. Accelerating the Internet in the presence of Big Data: Reducing user delays by leveraging historical user request patterns for web caching
ABSTRACT Approximately 4 billion people have access to the Internet, additionally 23 billion devices are connected as of 2018. This has allowed for a substantial growth in data collection which has allowed for Big Data to flourish. The continued increase in user, devices, and Big Data usage has created a significant intensification in Internet traffic. This

3. A compatibilidade da prática de zero-rating com a previsão de neutralidade de rede
Resumo Este artigo aborda a definição do conceito jurídico de neutralidade de rede conferida pela legislação brasileira, conforme interpretação dada ao art. 9º do Marco Civil da Internet, pela qual a neutralidade de rede refere-se ao tratamento isonômico dos pacotes de dados que transitam na rede, de modo a resguardar seu caráter aberto. A partir d

4. Accounting for greenhouse gas emissions from traffic rearrangement: a network vulnerability perspective
Abstract Paper aims This study aims to accounting for greenhouse gas emissions from traffic rearrangement, using a network vulnerability framework. Originality We present a new procedure to verify the effectiveness of accident risk as an attribute to find the most vulnerable links of a road network, estimating the amount emitted in the process.

5. Network Characteristics Analysis of Air Traffic Management Technical Support System Based on Multi-source Weighting
ABSTRACT In order to make reasonable suggestions for the expansion of the Air Traffic Management Technical Support System (ATMTSS), it is necessary to conduct a comprehensive analysis of the ATMTSS network. This paper constructs a multi-source weighted ATMTSS network which considers the working characteristics and geographical locations of the facilities. Th

6. A System to improve the management of 5G and IoT Networks by determining the Mobile Position
Abstract The interference in adjacent cells and the control of the boundaries have being vastly investigated since the conception of the first cell phone networks. A very large number of small cells are required for new 5G mobile networks, and therefore it is even more important to determine the correct mobile station positioning as well as the control bound

7. Keep calm e mude o código: um estudo de code switching no Facebook
RESUMO Este artigo tem como objetivo analisar a incidência do fenômeno code-switching na interação entre falantes bi/multilíngues, na rede social Facebook. Ao considerar o dinamismo e o caráter multimodal da comunicação, compreendemos que é fundamental que a formação de professores de línguas volte-se às discussões sobre os muitos cenários lin

8. COST-EFFECTIVE BANDWIDTH PROVISIONING IN MICROWAVE WIRELESS NETWORKS UNDER UNRELIABLE CHANNEL CONDITIONS
ABSTRACT Cost-effective planning and dimensioning of backhaul microwave networks under unreliable channel conditions remains a relatively underexplored area in the literature. In particular, bandwidth assignment requires special attention as the transport capacity of microwave links is prone to variations due to, e.g., weather conditions. In this paper, we f

9. COLUMN GENERATION BASED ALGORITHMS FOR THE CAPACITATED MULTI-LAYER NETWORK DESIGN WITH UNSPLITTABLE DEMANDS
ABSTRACT We investigate a variant of the Multi-Layer Network Design problem where minimum cost capacities have to be installed upon a virtual layer in such a way that (i) a set of traffic demands can be routed AND (ii) each capacity (subband) is assigned a route in the physical layer. The traffic demands cannot be splitted along several paths (nor even sever

10. Modeling an Optical Network Operating with Hybrid-Switching Paradigms
Abstract The continuous increasing of the Internet traffic has brought serious concerns about capacity exhaustion of the optical infrastructure in a medium term horizon. Taking into account the optical networks, comprising the Internet backbone, the strategies to avoid this catastrophic scenario point to the development of new technologies that enable the ca

11. Simulating a Multi-Vehicle Traffic Sensing System Based on Radio Tomographic Imaging
Abstract One of the most recently developed wireless technologies is Radio Tomographic Imaging (RTI). RTI employs a wireless sensor network that produces images of the change in the electromagnetic field of a monitored area using Received Signal Strength (RSS) measurements. This allows the tracking of device-free objects such as humans and cars. This paper i

12. A Performance Evaluation of WLAN-Femtocell-LTE beyond the Capacity Crunch. Does Femtocell have to overcome WLAN or can they coexist in HetNets?
Abstract This paper originates from a practical experiment based on Mesh Networks. The promising results obtained from this experiment prompted us to discuss in greater depth whether Wireless Local Area Networks (WLAN) are still useful for current communications. This means that on the one hand femtocells can be defined as small base stations that use the sa
