NB-IoT latency evaluation with real measurements
(2022-07)In the 3GPP LTE Release 13, NB-IoT was standardized to provide wide-area connectivity for IoT. To optimize network signaling and power consumption, control plane (CP) optimization was introduced. In Release 15, to support ... -
Network Anomaly Classification by Support Vector Classifiers Ensemble and Non-linear Projection Techniques
(Springer, 2013-09)Network anomaly detection is currently a challenge due to the number of different attacks and the number of potential attackers. Intrusion detection systems aim to detect misuses or network anomalies in order to block ports ... -
New open access software designed for the recognition of daily microstructures used in ageing fish
(2014-10-28)Ageing methods for most of the exploited fish species are not validated, and consequently age data series often have important gaps and uncertainty manifesting its consequences on age-based fisheries assessment. In ... -
Next-Generation Self-Organizing Networks through a Machine Learning Approach
(UMA Editorial, 2018-12-17)Para reducir los costes de gestión de las redes celulares, que, con el tiempo, aumentaban en complejidad, surgió el concepto de las redes autoorganizadas, o self-organizing networks (SON). Es decir, la automatización de ... -
