System architecture and deployment scenarios for SESAME: Small cEllS coordinAtion for Multi-tenancy and Edge services
(2016-05-17)
The surge of the Internet traffic with exabytes of data flowing over operators mobile networks has created the need to rethink the paradigms behind the design of the mobile network architecture. The inadequacy of the 4G ...
A Survey on the Contributions of Software-Defined Networking to Traffic Engineering
(IEEE, 2017-05-31)
Since the appearance of OpenFlow back in 2008, software-defined networking (SDN) has gained momentum. Although there are some discrepancies between the standards developing organizations working with SDN about what SDN is ...
A Robust Optimization Based Energy-Aware Virtual Network Function Placement Proposal for Small Cell 5G Networks with Mobile Edge Computing Capabilities
(Hindawi, 2017)
In the context of cloud-enabled 5G radio access networks with network function virtualization capabilities, we focus on the virtual network function placement problem for a multitenant cluster of small cells that provide ...
QoE-Oriented Mobile Edge Service Management Leveraging SDN and NFV
(Hindawi, 2017)
5G envisages a "hyperconnected society" where trillions of diverse entities could communicate with each other anywhere and at any time, some of which will demand extremely challenging performance requirements such as ...
A Novel Scheduling Index Rule Proposal for QoE Maximization in Wireless Networks
(Hindawi Publishing, 2014)
This paper deals with the resource allocation problem aimed at maximizing users' perception of quality in wireless channels with time-varying capacity. First of all, we model the subjective quality-aware scheduling problem ...
Improving Content Delivery Efficiency through Multi-Layer Mobile Edge Adaptation
(IEEE, 2015-11)
This paper presents a novel architecture for optimizing the HTTP-based multimedia delivery in multi-user mobile networks. This proposal combines the usual client-driven dynamic adaptation scheme DASH-3GPP with network-assisted ...
Dealing with Energy-QoE Trade-Offs in Mobile Video
(Hindawi Publishing Corporation, 2013)
Scalable video coding allows an efficient provision of video services at different quality levels with different energy demands. According to the specific type of service and network scenario, end users and/or operators ...
Polymer-Optical-Fiber Lasers and Amplifiers Doped with Organic Dyes
(MDPI, 2011-09)
Polymer optical fibers (POFs) doped with organic dyes can be used to make efficient lasers and amplifiers due to the high gains achievable in short distances. This paper analyzes the peculiarities of light amplification ...
Flicker of Modern Lighting Technologies Due to Rapid Voltage Changes
(MDPI, 2019-03-01)
The purpose of the present paper is to evaluate the sensitivity of modern lighting technologies to different types of RVCs. In order to do that, 27 modern lampsmainly LEDhave been subjected to real RVCs and their response ...
LSTM based voice conversion for laryngectomees
(International Speech Communication Association, 2018-11-23)
This paper describes a voice conversion system designed withthe aim of improving the intelligibility and pleasantness of oe-sophageal voices. Two different systems have been built, oneto transform the spectral magnitude ...
