Special Issue Information

Dear Colleagues,

This Special Issue will include selected papers from the 10th IFIP Wireless and Mobile Networking Conference (WMNC 2017), to be held in Valencia, Spain, 25–27 September, 2017, and from XIII Jornadas de Ingeniería Telemática (JITEL 2017), to be held in Valencia, Spain, 27–29 September, 2017.

The scopes of the conferences include mobile and wireless networks, services, applications and mobile computing, Personal Wireless Communication, and any topic related to communication networks.

The authors of selected papers from WMNC 2017 and JITEL 2017 within the scope of this journal will be invited to submit extended and enhanced versions of their papers to this Special Issue. These extended papers must contain considerable amounts of new material, and will be subject to a new round of reviews before being published in the Special Issue.

The lack of privileged access to emergent and operational deployments is one of the key matters during validation and testing of novel telecommunication systems and technologies. This matter jeopardizes the repeatability of experiments, which results in burdens for innovation and research in these areas. In this light, we present a method and architecture to make the software-driven definition of virtual testbeds easier. As distinguishing features, our proposal can mimic operational deployments by using high-dimensional activity patterns. These activity patterns shape the effect of a control module that triggers agents for the generation of network traffic. This solution exploits the capabilities of network emulation and virtualization systems, which nowadays can be easily deployed in commodity servers. With this, we accomplish a reproducible definition of realistic experimental conditions and the introduction of real agent implementations in a cost-effective fashion. We evaluate our solution in a case study that is comprised of the validation of a network-monitoring tool for Voice over IP (VoIP) deployments. Our experimental results support the viability of the method and illustrate how this formulation can improve the experimentation in emergent technologies. Full article

Wireless access technologies are widespread in domestic scenarios, and end users extensively use mobile phones or tablets to browse the Web. Therefore, methods and platforms for the measurement of network key performance indicators must be adapted to the peculiarities of this environment. In this light, the experiments should capture the true conditions of such connections, particularly in terms of the hardware and multi-device interactions that are present in real networks. On the basis of this, this paper presents an evaluation of the capabilities of several affordable commercial off-the-shelf (COTS) devices as network measuring probes, for example, computers-on-module or domestic routers with software measurement tools. Our main goal is to detect the limits of such devices and define a guide of good practices to optimize them. Hence, our work paves the way for the development of fair measurement systems in domestic networks with low expenditures. The obtained experimental results show that these types of devices are suitable as network measuring probes, if they are adequately configured and minimal accuracy losses are assumable. Full article

The demand for video traffic is increasing over mobile networks that are taking another shape by its heterogeneity. However, the wireless link capacity cannot cope with the traffic demand. This is due to the interference problem that can be considered as the most important challenge in heterogeneous networks. Consequently, it will result in poor service for the quality of video streaming such as the bad quality delivery, service interruption, etc. In this paper, we propose a solution for interference mitigation in the context of heterogeneous networks through power control mechanism, while guaranteeing the Quality of Service of the video streaming. We derive a model for adapting the video bit rate to match the channel’s achievable bit rate. Our results demonstrate a high satisfaction for video streaming in terms of delay and throughput.

Web Content Management Systems (WCMS) play an increasingly important role in the Internet’s evolution. They are software platforms that facilitate the implementation of a web site or an e-commerce and are gaining popularity due to its flexibility and ease of use. In this work, we explain from a tutorial perspective how to manage WCMS and what can be achieved by using them. With this aim, we select the most popular open-source WCMS; namely, Joomla!, WordPress, and Drupal. Then, we implement three websites that are equal in terms of requirements, visual aspect, and functionality, one for each WCMS. Through a qualitative comparative analysis, we show the advantages and drawbacks of each solution, and the complexity associated. On the other hand, security concerns can arise if WCMS are not appropriately used. Due to the key position that they occupy in today’s Internet, we perform a basic security analysis of the three implement websites in the second part of this work. Specifically, we explain vulnerabilities, security enhancements, which errors should not be done, and which WCMS is initially safer. Full article
