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 ...
Introducing mobile edge computing capabilities through distributed 5G Cloud Enabled Small Cells
(2016)
Current trends in broadband mobile networks are addressed towards the placement of different capabilities at the edge of the mobile network in a centralised way. On one hand, the split of the eNB between baseband processing ...
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 ...
Eurobalise-Train communication modelling to assess interferences in railway control signalling systems
(Macrothink Institute, 2016-05-10)
The evolution of the railway sector depends, to a great extent, on the deployment of advanced railway signalling systems. These signalling systems are based on communication architectures that must cope with complex ...
Characterisation of Exposure to Non-Ionising Electromagnetic Fields in the Spanish INMA Birth Cohort: Study Protocol
(Biomed Central, 2016-02-18)
Background: Analysis of the association between exposure to electromagnetic fields of non-ionising radiation (EMF-NIR) and health in children and adolescents is hindered by the limited availability of data, mainly due to ...
