When telecommunication infrastructure is damaged by natural disasters, creating a network that can handle voice channels can be vital for search and rescue missions. Unmanned Aerial Vehicles (UAV) equipped with WiFi access points could be rapidly deployed to provide wireless coverage to ground users. This WiFi access network can in turn be used...

We propose a novel cross-layer scheme to reduce energy consumption in wireless sensor networks composed of IEEE 802.15.4 IoT devices with adjustable transmit power. Our approach is based on the IETF's Routing Protocol for Low power and lossy networks (RPL). Nodes discover neighbors and keep fresh link statistics for each available transmit...

This paper formulates a new problem for the optimal placement of Unmanned Aerial Vehicles (UAVs) geared towards wireless coverage provision for Voice over WiFi (VoWiFi) service to a set of ground users confined in an open area. Our objective function is constrained by coverage and by VoIP speech quality and minimizes the ratio between the...

Most anomaly-based intrusion detectors rely on models that learn from a training dataset whose quality is crucial in their performance. Albeit the properties of suitable datasets have been formulated, the influence of the dataset size on the performance of the anomaly-based detector has received scarce attention so far. In this work, we...

The unavailability of information and communication services due to network-related incidents may have a significant impact on large organizations. Network incidents can hence be viewed as a risk for organizations whose consequences are not accounted for by traditional network design problems. In this work, we address the problem of designing a...

Unmanned Aerial Vehicle (UAV) networks have emerged as a promising means to provide wireless coverage in open geographical areas. Nevertheless, in wireless networks such as WiFi, signal coverage alone is insufficient to guarantee that network performance meets the quality of service (QoS) requirements of real-time communication services, as it...

This work shows a testing tool used in Fundamentals of Programming II laboratory in Telecommunication Technologies Engineering Degree at University of Sevilla to check the student project. This tool allows students to test the proper operation of their project in autonomous way. This is a flexible and useful tool for testing the project because...

The dataset is organized in a tree structure (subdirectories) each containing different types of files or sets. As provided, 5 sets of files and two partitioning schemes are considered. The partition files are not directly provided but can be generated from the files using the provided script. The following sets of files (subdirs) are...

Signature-based Intrusion Detection Systems (SIDS) play a crucial role within the arsenal of security components of most organizations. They can find traces of known attacks in the network traffic or host events for which patterns or signatures have been pre-established. SIDS include standard packages of detection rulesets, but only those rules...

La mayor parte de los sistemas de detección de intrusiones (IDS) operativos se basan en el uso de firmas que permiten identificar ataques conocidos. La dependencia de estos IDS con la actualización de las bases de datos de firmas constituye una de sus mayores limitaciones, siendo de interés el desarrollo de sistemas que posibiliten la...

Continuity of care requires the exchange of health information among organizations and care teams. The EU General Data Protection Regulation (GDPR) establishes that subject of care should give explicit consent to the treatment of her personal data, and organizations must obey the individual's will. Nevertheless, few solutions focus on...
