Fronthaul is a network segment between Remote Radio Head (RRH) situated on the antenna site, and the Base Band Unit (BBU) localized in the Central Office. It uses the Common Public Radio Interface protocol (CPRI). A point to point physical topology can be used, but the deployment of this configuration uses a lot of optical resources. Coarse Wavelength Division Multiplexing (CWDM) dual fiber and single fiber links can be used to reduce the number of optical fibers. This paper focuses on the single fiber links because in addition to others advantages of this system, it uses less fiber than the CWDM dual fiber system. The difficulty to build a complete fronthaul single fiber solution is to provide a monitoring system in addition to CPRI data transport. We propose to characterize, in terms of Bit Error Rate (BER) CPRI requirements, a fronthaul CWDM single fiber link up to 4.9 Gbits/s. Furthermore, an innovative single fiber monitoring scheme, based on the reduction of Rayleigh Backscattering light in the fiber is illustrated. This reduction is carried out due to the combination of a Polarization Beam Combiner and a Faraday Rotator Mirror. This reduction allows improving the capacity of failure detection of the fiber in the CWDM single fiber technology.
前传是位于天线站点的远程无线电头(RRH)和位于中央局的基带单元(BBU)之间的一个网段。它使用CPRI (Common Public Radio Interface protocol)协议。可以使用点到点的物理拓扑，但这种配置的部署需要使用大量的光资源。可以使用粗波分复用(CWDM)双光纤和单光纤链路来减少光纤的数量。本文将重点放在单光纤链路上，因为除了该系统具有其他优点外，它比CWDM双光纤系统使用更少的光纤。构建完整的前传单光纤解决方案的难点在于除了CPRI数据传输之外还要提供一个监控系统。根据误码率(BER) CPRI要求，我们建议描述高达4.9 Gbits/s的前传CWDM单光纤链路。此外，本文还提出了一种基于减少光纤中瑞利背散射光的单光纤监测方案。这种减少是由于偏振光束组合器和法拉第旋转镜的组合而进行的。这种减少可以提高CWDM单光纤技术中光纤故障检测的能力。

This paper proposes a new model for the management of virtual radio resources with traffic offloading support. The model has two key components: the estimation of network capacity and the data rate allocation. In the first one, the probability description of Signal-to-Interference-plus-Noise Ratio is used to obtain cumulative and density functions for the total network throughput. The primary objective in the second one is to achieve the maximum weighted throughput, subject to global network constraints. By using weights in an objective function, a prioritisation among services is achieved. The total network capacity, the SLAs (Service Level Agreements) of Virtual Network Operators, and fairness, are the constraints in this optimisation problem. The novelty of this paper is the addition of support for traffic offloading by considering the collision rates in Wi-Fi. The aim is to prioritise services with higher data rate per session in the offloading procedure, since it leads to a lower collision rate and a higher network throughput. A practical heterogeneous network is considered as a case study, in order to evaluate the model performance. Results show an increase of 2.5 times in network capacity, by implementing an access point at the centre of each cell. The good performance of the model and the VNOs' SLAs effect is demonstrated through numeric results.

Future Internet may be comprised of interconnected multiple software-defined networks (SDN), where each domain is administered by a different controller or control plane. Provisioning of an end-to-end flow-path across such a network with specific service levels requires collaboration between domain controllers across control planes. A service-enabled flow-path shall be quality of service (QoS) enabled, reliable and/or secure, which requires a transport path with certain quantitative service level requirements such as high throughput, low packet loss, or high availability. Each SDN controller can autonomously determine such end-to-end flow-paths when all other SDN controllers periodically advertise to other controllers its available service-enabled paths. Doing so, each SDN controller is presented with several service-enabled path alternatives, crossing other domains, to choose from. We propose a multi-domain SDN controller design, wherein each SDN controller shares its network's “summarized” topology of service-enabled paths with other SDN controllers, such that all domains (controllers) have real-time autonomous decision making capability for end-to-end flow-path selection. We also describe how an SDN controller can reserve and release a flow traversing other SDN domains.

In the context of the fast development of millimeter-wave (mmW) technologies for future 5G cellular networks and concerns related to their possible impact on the human health, this paper introduces a first analysis on the mmWs interaction with the human body. Firstly, the main regulations on the exposure limits at mmWs are reviewed. Secondly, an investigation on the skin modeling in terms of homogeneous vs. multilayer model is performed. In particular, power reflection coefficients and power density distributions are compared for different models. Our results provide an insight on the choice of an appropriate human body model for dosimetric analysis in the 60 GHz band.

Anomaly detection of Internet traffic is a network service of primary importance, given the constant threats that impinge on Internet security. From a statistical perspective, traffic anomalies can be considered outliers, and must be handled through effective outlier detection methods, for which feature selection is an important pre-processing step. Feature selection removes the redundant and irrelevant features from the detection process, increasing its performance. In this work, we consider outlier detection based on principal component analysis, and feature selection based on mutual information. Moreover, we address the use of kernel density estimation (KDE) to estimate themutual information, which is designed for continuous features, and avoids the discretization step of histograms. Our results, obtained using a high-quality ground-truth, clearly show the usefulness of feature selection and the superiority of KDE to estimate the mutual information, in the context of Internet traffic anomaly detection.

Nowadays, users are demanding access to video content anytime and anywhere. LTE broadcast services and video streaming services can reduce the resources used by telecommunication companies to give access to video content and open up new business opportunities. In this context, testbeds and simulation tools can help in the analysis of the different parameters that need to be considered in the deployment of video services based on LTE. In this paper, we describe the design and implementation of an open-source virtualized platform that supports both LTE broadcast services and video streaming services. The testbed is being used both over real LTE networks and LTE network emulations to analyze the performance of video streaming services and to validate new proposals.

The paper addresses the performance evaluation via the Cramer-Rao Lower Bound (CRLB) of power-based localization of a source in spatially-correlated log-normal propagation. The novel element is the inclusion and assessment of the impact of conditioning measurements on such performance. The proposed model parameterizes performance by both the sensor topology (density, positioning) producing the current measurements as well as by conditioning measurements (essentially, prior or training data) which reduce the statistical uncertainty in the model. Experimental results for indoor and outdoor environments are presented which quantify the expected localization accuracy, as well as identify practical issues to be further addressed. One main concern is the quantification of scaling on required sensor-network size for achieving a pre-specified localization accuracy.

In this paper the Wireless Resource Sharing Method (WRSM) for wireless sensor and actuator networks is introduced. The proposed method aims to enable distributed and dynamic discovery, negotiation and sharing of tasks and resources (e.g., hardware accelerators, communication interfaces or memory) between the neighboring nodes in heterogeneous and multi-tasked IoT-like network environment. The paper introduces the WRSM, discusses challenges faced and technical solutions developed for implementing it in practice, and reports results of the first hardware tests. The presented results confirm feasibility of the proposed method, highlight some limitations of the current solution and point out directions of further work.

Parallel TCP connections are used for large scientific dataset transfers to increase throughput. Therefore, to accurately characterize big-data movement, it is important to reconstruct parallel flowsets from traffic measurements. In this work, we start with NetFlow records collected in an operational research-and-education network across which large scientific datasets are moved routinely, reconstruct individual elephant flows from the NetFlow records, and assemble parallel flowsets from elephant flows. Our findings are as follows. The top 1% of flowset sizes were in the hundreds of GBs to low TBs range, 95% of flowsets had rates less than 2.5 Gbps, and 99% of flowsets had durations shorter than 4 hours. Median flowset rate increases and rate variance decreases with increasing number of per-flowset component flows. Such findings are useful for network planning, traffic engineering, and for improving user performance, since large dataset transfers are among the most demanding of network applications.

In this paper we present the results of spectrum occupancy measurements conducted in different urban environments, in greater Melbourne area, Australia. We capture the dynamic nature of spectrum occupancy seen from a spatial perspective, by conducting spectrum monitoring measurements on board a mobile vehicle. With a wide spectrum window selected from 400 to 6000 MHz we aim to shed some light on the feasibility of utilizing smart spectrum access techniques facilitated by cognitive radios.
