Fog computing is an emerging architecture for processing, storing, and controlling the data at the edge of the networks, which is becoming a popular technology for Internet of Things (IoT). As a next-generation networking architecture, Information-Centric Network (ICN) has been introduced into networked fogs to establish efficient data exchange based on name, caching, content features, etc., which gives the IoT an opportunity to store the huge geo-distributed data at the edge of the networks and be less dependent on the Cloud, thus fulfilling the delay-sensitive needs of the end-users. Nevertheless, efficient distributed storage is a must for information-centric fog networks, because of the huge content exchange and geo-distributed data. To address this, this paper proposes an efficient storage scheme by integrating Binary Reed-Solomon erasure code with ICN mechanism in fog networks. Specifically, the data are encoded into named data blocks and are distributed as well as stored into distributed fog nodes. The fog network performs information-centered with horizontal fog-to-fog communications to retrieve the data blocks efficiently. Moreover, the data is then recovered even with some of the data blocks missing, thus ensuring the reliability of storage at distributed fogs. Simulation results show the efficiency and advantages of the proposed distributed storage scheme.

The rise of adblockers is creating lots of concerns to the online content publishing industry, as it severely affects the possibility to offer free-content to end-users by subsidizing the fruition costs with advertisements.While many detection techniques have been proposed as a countermeasure to the diffusion of adblocks, they either rely on the injection of code in the served web pages, or require to perform passive measurements for a long time, thus leading to high costs and delays before collecting the desired information. Motivated by these reasons, in this paper we propose a novel technique to conduct in-network adblock usage measurements, inspecting only few minutes of network traffic. Our approach relies on network traffic inspection, and classification with machine learning techniques to detect whether the user is blocking, or not, the advertisements.Key findings obtained show that by inspecting only few minutes of network traffic, we can reliably perform the detection with an accuracy up to 99%, with a negligible computational overhead.

This paper presents an overview of the interoperability concepts along with the challenges for the IoT domain and the upcoming Web 3.0. We identify four levels of interoperability and the relevant solutions for accomplishing vertical and horizontal compatibility between the various layers of a modern IoT ecosystem, referred to as: technological, syntactic, semantic, and organizational interoperability. The goal is to achieve cross-domain interaction and facilitate the proper usage and management of the provided IoT services and applications. An interoperability framework is also proposed where the involved system components can cooperate and offer the seamless operation from the device to the backend framework. This by-design end-to-end interoperation enables the interplay of several complex service composition settings and the management of the system via patterns. The overall proposal is adopted by the EU funded project SEMIoTICS as an enabler towards the IoT and Web 3.0, even when products from different vendors are utilized.

The next wave of innovation will certainly generate numerous new opportunities for emerging technology solutions based on networking services and applications with stringent key performance indicators (KPIs) such as ultra-low 1 ms latency, a 1000 fold bandwidth increase, 99.99 % reliability and availability, which are immensely above those supported by current mobile networks. A new architecture of mobile networking called cloud radio access network (C-RAN) has been introduced over the last few years not only to supporting these indicators, but also to increasing scalability, manageability, and flexibility of mobile systems. In this context, this paper addresses the principal technology enablers and their features for C-RAN fronthaul architectures of the $5^{th}$ generation (5G) mobile networks, namely space-division multiplexing (SDM), massive multiple-input multiple-output (MIMO) signaling, analog radio-over-fiver (A-RoF), and millimeter wave (mmWave) frequency technology. These technologies pave the way towards a truly viable and efficient fronthaul infrastructure for 5G mobile communications with connectivity for thousands of users and strict latency control. In this fashion, we perceive a networkinfrastructure scenario with seamless starting and ending interfaces by exploiting space diversity in both radio frequency and optical domains with efficient integrated photonics technology-all combined with adaptive softwaredefined network programming, so as to satisfy the 5G KPIs. Furthermore, we address the most relevant features of these technologies as a potential guideline for potential fronthaul infrastructure deployment of next generation mobile networks.

A Chatbot is an application that is designed to provide automated contextual communication. Today most chatbots are implemented on top of or as a gateway to popular messaging services, such as Facebook Messenger, Skype and Viber. Chatbots can be classified into many categories regarding their usage, such as conversational commerce, customer support, education, marketing and others. Due to their agile deployment ability on top of virtualized and serverless environments,chatbots are expected to play a pivotal role in the forthcoming 5G networks, which support virtualization capabilities at the edge of the network, making feasible the provision of diversified chatbot services customized to each user needs and requests. However, chatbot QoS might be affected under congested network conditions or in areas with poor signal reception quality. Currently, the performance of the chatbot has not been researched, while the users are experiencing only the results of the potential QoS degradation, such as loss or re-ordering of messages. This paper provides an experimental study of the chatbot apps performance/QoS under different network and reception conditions. The experiment was conducted using the 5G mobile network emulation testbed created and provided by the EU-funded TRIANGLE project.

In this paper, we address the application of topological interference management (TIM) on a clustered network of Device-to-Device (D2D) devices which are not aware of the surrounding channel state information (CSI), but only of the connectivity pattern. Our main objective is to develop a proper clustering algorithm that leads to increasing the total system degrees-of-freedom (DoF). For this, we model the interference network as a connected graph, transforming the clustering problem into a graph partitioning problem. To solve it, we base our method on the semidefinite problem (SDP) relaxation of the maximum-k-cut algorithm, while accounting for the maximum number of devices allowed inside the multiple-input multiple-output (MIMO) cluster environment. Simulation results show that proper clustering combined with TIM design renders TIM more scalable, and able to increase the system DoF.

The fifth generation of mobile networks is rapidly evolving and novel architectures and communication paradigms are constantly proposed. Heterogeneous wireless networks and particularly dense small cells are a key enabler for increased throughput and high-quality communications, although such densely distributed access networks suffer the effect of inter-cell interference. The coordinated multi-point operation is already considered as a promising technique for mitigating this problem by allowing the coordination of multiple transmission points that serve the user. In this study, the coordinated multi-point is applied in a simulated wireless network in order to measure its performance under varying conditions, including a varying number of static or roaming users, variable required SINR levels and transmission power required to satisfy the requirements. The simulation results indicate that the scheme can achieve significantly low transmission power levels, while serving wireless users at the edge of the cells with SINR of $20dB$, suggesting this technique for future network implementations.

Virtual, augmented and mixed reality are expected to grow rapidly in popularity as the technology gets more mature over the coming years. For mobile networks these applications can put quite challenging requirements. In particular when the user devices shall have low weight and low energy consumption it may be necessary to offload some of the processing to edge cloud servers. This implies strict requirements on latency and high data rate between the edge server and the user device. In this paper we discuss the requirements for different quality levels of virtual reality and the feasibility of providing these in 4G and 5G cellular networks. In particular, we show how reduced latency can reduce the bit rate requirements and enable photo realistic XR over mobile networks.
