Joint route selection and split level management for 5G C-RAN
(2021-06-22)
Article
Open AccessThis work tackles the problem faced by network/ infrastructure providers of jointly selecting routing and functional split level to satisfy requests from virtual mobile network operators (vMNOs). We build a novel system ... -
A multi-stage graph based algorithm for survivable Service Function Chain orchestration with backup resource sharing
(Elsevier, 2021-06)
Article
Restricted access - publisher's policyNetwork softwarisation introduces flexibility in network management by enabling the deployment of network functions as software modules running on virtual machines. However, this creates new concerns for service availability ... -
A multi-domain VNE algorithm based on load balancing in the IoT networks
(Springer, 2021-02-06)
Article
Restricted access - publisher's policyThe coordinated development of big data, Internet of Things, cloud computing and other technologies has led to an exponential growth in Internet business. However, the traditional Internet architecture gradually shows a ... -
A deep reinforcement learning-based algorithm for reliability-aware multi-domain service deployment in smart ecosystems
(2020-10-05)
Article
Open AccessThe transition towards full network virtualization will see services for smart ecosystems including smart metering, healthcare and transportation among others, being deployed as Service Function Chains (SFCs) comprised of ... -
Slicing in WiFi networks through airtime-based resource allocation
(2018-11-23)
Article
Open AccessNetwork slicing is one of the key enabling technologies for 5G networks. It allows infrastructure owners to assign resources to service providers (tenants), which will afterwards use them to satisfy their end-user demands. ... -
Slicing with guaranteed quality of service in WiFi networks
(2020-06-30)
Article
Open AccessNetwork slicing has recently been proposed as one of the main enablers for 5G networks. The slicing concept consists of the partition of a physical network into several self-contained logical networks (slices) that can be ... -
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
Open AccessWe 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). ...
