Although Fog computing specifies a scalable architecture for computation, communication and storage, there is still a demand for better Quality of Service (QoS), especially for agile mobile services. Both industry and academia have been working on novel and efficient mechanisms for QoS provisioning in Fog computing. This paper presents a classification of services according to their QoS requirements as well as Class of Service for fog applications. This will facilitate the decision-making process for fog scheduler, and specifically to identify the timescale and location of resources, helping to make scalable the deployment of new applications. Moreover, this paper introduces a mapping between the proposed classes of service and the processing layers of the Fog computing reference architecture. The paper also discusses use cases in which the proposed classification of services would be helpful.

In digital communication systems the use of filters that fulfill the first Nyquist criterion (Nyquist-I), guarantees that a sequence of pulses will not be affected by inter-symbol interference (ISI) if the receiver samples signals at optimum and uniformly spaced instants. In this manuscript the Nyquist-I pulse, called exponential linear pulse (ELP), is evaluated in the time and frequency domain using different evaluation tools and compared with other existing pulses. The eye diagram is simulated in presence of time sampling errors and the approximated average bit error rate (BER) is computed considering the ideal and truncated version of the pulses. Finally, the spectral energy distribution and spectral regrowth of the pulses are presented for comparison purposes. Numerical results show that the ELP outperforms other existing pulses in terms of the eye diagram opening and BER, evaluated for various symbol timing errors and roll-off factors. However, the good performance of the ELP in the time domain is at the expenses of introduction of out-of band radiation compared to the traditional Raised Cosine pulse; therefore, a trade-off between BER and out-of-band radiation exists.

Asynchronous and cyclostationary impulsive noise can severely impact the bit-error-rate (BER) of OFDM-based powerline communication systems. In this paper, we analyze an adaptive nonlinear analog front end filter that mitigates various types of impulsive noise without detrimental effects such as self-interference and out-of-band power leakage caused by other nonlinear approaches like clipping and blanking. Our proposed Adaptive Nonlinear Differential Limiter (ANDL) is constructed from a linear analog filter by applying a feedback-based nonlinearity, controlled by a single resolution parameter. We present a simple practical method to find the value of this resolution parameter that ensures the mitigation of impulsive without impacting the desired OFDM signal. Unlike many prior approaches for impulsive noise mitigation that assume a statistical noise model, ANDL is blind to the exact nature of the noise distribution, and is designed to be fully compatible with existing linear front end filters. We demonstrate the potency of ANDL by simulating the OFDM-based narrowband PLC compliant with the IEEE standards. We show that the proposed ANDL outperforms other approaches in reducing the BER in impulsive noise environments.

Software defined Networks (SDN) is a paradigm that promises to facilitate the management of all types of networks, including the Wireless Mesh Networks (WMN). This integration enables an environment with enough resources and coverage to meet the demands of users, and thanks to a centralized network, resources can be managed in a better way. There are multiple simulators/emulators available, integrating SDN and WMN, but most of them do not have IEEE802.11s support. This paper proposes a framework that integrates NS-3, Open Vswitch, and Linux network namespaces, to create an environment that allows emulating IEEE802.11s SDN-WMN scenarios. The framework is used to evaluate the throughput and delay of a real-time streaming video application.

In this paper, we address the problem of estimating channel impulse response (CIR) and carrier frequency offset (CFO) in OFDM systems utilizing the method of maximum likelihood. When the CFO is small, Moose's technique for CFO estimation is accurate and numerically efficient. However, if the CFO is high, there are no straightforward solutions for its estimation. We show that the log-likelihood function of the CIR and the CFO can be concentrated in one variable (the CFO), and that its estimation can be accurately carried out by first performing a coarse line search and then applying Newton's method at a low computational cost. We illustrate the benefits of our proposal via numerical simulations.

Telecommunications authorities are interested in knowing the real spectrum occupancy with the aid of several participants in the field of telecommunications. Therefore, several spectrum measurement campaigns have been made around the world. The results show a low spectrum occupancy leading to an inefficient use of the spectrum. This suggests the use of technologies like cognitive radio as a solution to improve the issue of spectrum inefficiency. Besides, the regulatory authorities are considering to cease some obsolete services so as to improve the use of the spectrum. For example, analog TV broadcasting is being replaced with digital TV, which is a process called Analog Switch-Off (ASO). In a previous work, before ASO we conducted spectrum measurements in the City of San Luis Potosi, Mexico, for the frequency range between 30 MHz and 910 MHz. In this paper, we perform a new measurements campaign with the same methodology. The aim of this new study is to analyze how the spectrum occupancy has evolved after the Mexican government and telecommunications companies implemented ASO. Thus, we present the results of spectrum occupancy after ASO with an average duty cycle of 15% for the frequency range just mentioned.

In this paper, self-interference (SI) cancellation algorithm based on Space Projection Algorithm (SPA) is proposed for Full-Duplex (FD) Multiple-Input Multiple-Output (MIMO) relays in an indoor wireless communication system. The simultaneous transmission and reception of the same radio signal imply a SI around the relay transceiver. The principal challenge of implementing the FD-MIMO relay is to this interference and increase the relaying capacity. To reach this aims, an efficient algorithm using SPA filters is designed and validated by simulation. The results of proposed method outperform the exiting works in term of BER for the QPSK modulation.

For complex large scale networks, like social networks, it is typically impossible to observe complete information about their topology structure or link weight directly. A recent proposal, the network resonance method, can estimate the eigenvalues and eigenvectors of the Laplacian matrix for representing network structure, by using the resonance phenomena of oscillation dynamics on networks. However, it is generally not possible to observe all the eigenvalues and eigenvectors. In practice, the observed values must be assumed to include some non-negligible errors. This paper uses compressed sensing to create a new method of reconstructing the original Laplacian matrix from some of its eigenvalues and eigenvectors. Since almost all node pairs in social networks have no link, we can expect that compressed sensing will be effective. The estimated Laplacian matrix of a social network enables to us to know its structure and link weights.

Large Forest Fires are one of the most destructive and recurring natural disaster types around the world, and year after year they leave environmental, material and human irreparable losses in the social nuclei in which they occur. To face them, it is essential to have a Situation Awareness that allows decisions making according to reality, promoting the collaboration between the all involved and execution of effective actions to manage the fire. This paper describes the architecture for the implementation of a Command and Control Information System, which makes it possible to get and share with all stakeholders, the required information to confirm an accurate and timely Situation Awareness of disaster scene. It is based on the establishment of a flexible, resilient and scalable Wireless Mesh Network, which supporting communications both inside and outside the area affected by the fire, and allows the surveillance of environment state and the response units deployed within the same.

Location-aware devices will create new services and applications in emerging fields such as autonomous driving, smart cities, and the Internet of Things. Many existing localization systems rely on anchors such as satellites at known positions which broadcast radio signals. However, such signals may be blocked by obstacles, corrupted by multipath propagation, or provide insufficient localization accuracy. Therefore, ubiquitous localization remains an extremely challenging problem. This paper introduces Peregrine, a 3-D cooperative network localization and navigation (NLN) system. Peregrine nodes are low-cost business-card-sized devices, consisting of a microprocessor, a commercially available ultra-wideband (UWB) radio module, and a small battery. Recently developed distributed algorithms are used in Peregrine to solve the highly interrelated problems of node inference and node activation in real-time, enabling resource efficiency, scalability, and accuracy for NLN. Node inference-based on the recently introduced sigma point belief propagation (SPBP) algorithm-enables spatiotemporal cooperation in realtime and estimates the nodes' positions accurately from UWB distance measurements. A distributed node activation algorithm controls channel access to improve the efficiency and reduce the localization error of the network. Contributions of each algorithmic component to overall system performance are validated through indoor localization experiments. Our results show that Peregrine achieves decimeter-level 3-D position accuracy in a challenging propagation environment.
