A novel dynamic programming inspired algorithm for embedding of virtual networks in future networks
(2020-06-06)
Article
Restricted access - publisher's policyNetwork virtualization is envisioned to support flexible, cost effective and on-demand deployment of multiple Virtual Networks (VNs) on a shared underlying infrastructure. A key challenge under the virtualization paradigm ... -
Extent prediction of the information and influence propagation in online social networks
(2020-03-27)
Article
Restricted access - publisher's policyWe present a new mathematical model that predicts the number of users informed and influenced by messages that are propagated in an online social network. Our model is based on a new way of quantifying the tie-strength, ... -
An alternative procedure to obtain the mortality rate with non-linear functions: Application to the case of the Spanish population
(Public Library of Science (PLOS), 2019-10-15)
Article
Open AccessThis paper presents an alternative calculation procedure to calculate the mortality rate, exploiting the data available in the Eurostat demography database for Spain. This methodology has been devised based on two of the ... -

Feasibility study to evaluate the potential entry of a new F-MVNO into the Spanish mobile market
(Sciencedomain International, 2017)
Article
Open AccessThe mobile market until a decade ago had been composed mainly of Mobile Network Operators (MNOs). To promote greater competition in this market the European Commission (EC) has promoted various actions in the regulatory ... -
Self-adaptive online virtual network migration in network virtualization environments
(Wiley-Blackwell, 2019-01-01)
Article
Open AccessIn Network Virtualization Environments, the capability of operators to allocate resources in the Substrate Network (SN) to support Virtual Networks (VNs) in an optimal manner is known as Virtual Network Embedding (VNE). ... -
Fast and efficient energy-oriented cell assignment in heterogeneous networks
(Springer, 2019-06-10)
Article
Open AccessThe cell assignment problem is combinatorial, with increased complexity when it is tackled considering resource allocation. This paper models joint cell assignment and resource allocation for cellular heterogeneous networks, ... -
Management and orchestration challenges in network functions virtualization
(2016-01)
Article
Open AccessNFV continues to draw immense attention from researchers in both industry and academia. By decoupling NFs from the physical equipment on which they run, NFV promises to reduce CAPEX and OPEX, make networks more scalable ... -
Updated taxonomy for the network and service management research field
(2018-07-01)
Article
Open AccessNetwork and service management is an established research field within the general area of computer networks. A few years ago, an initial taxonomy, organizing a comprehensive list of terms and topics, was established through ... -
Generating demand functions for data plans from mobile network operators based on users’ profiles
(2018-01-22)
Article
Open AccessThe evaluation of pricing approaches for mobile data services proposed in the literature can rarely be done in practice. Evaluation by simulation is the most common practice. In these proposals demand and utility functions ... -
A social model based on customers’ profiles for analyzing the churning process in the mobile market of data plans
(2018-01-09)
Article
Open AccessMobile Network Operators (MNOs) present wireless services of the same kind in identical zones, clients select the service taking into account any element they consider relevant. Churning hits on the design of the network ... -
Semantically enhanced mapping algorithm for affinity-constrained service function chain requests
(2017-06-01)
Article
Open AccessNetwork function virtualization (NFV) and software defined networking (SDN) have been proposed to increase the cost-efficiency, flexibility, and innovation in network service provisioning. This is achieved by leveraging ...
