GAUChO - A Green Adaptive Fog Computing and Networking Architecture

PRIN: PROGETTI DI RICERCA DI RILEVANTE INTERESSE NAZIONALE Bando 2015

Fog Computing (FC) is an emerging paradigm that extends Cloud Computing towards the edge of the network. In particular, FC refers to a distributed computing infrastructure confined on a limited geographical area in which some applications/services run directly at the network edge in smart end-devices. The goal of FC is to improve efficiency and reduce the amount of data that needs to be transported to the Cloud for massive data processing, analysis and storage. However, in latency-sensitive and energy-efficient (i.e., green) applications, the FC paradigm per se might not be appropriate and (at least) part of the computation has to be transferred to the sensor/actuator end-devices level. Here, decisions must be usually taken in a very short time and energy and power constraints constitute a limiting factor. Furthermore, the design of efficient solutions within FC also requires investigate a novel communication/networking paradigm, called Fog Networking (FN), in order to meet specific configurability, adaptability, flexibility and energy/spectrum-efficiency constraints. Being currently FC and FN features designed, optimized and implemented independently each other, the GAUChO project aspires at designing a novel distributed and heterogeneous architecture able to functionally integrate and jointly optimize FC and FN capabilities in the same platform. The joint FC+FN architecture, representing the overall outcome of the project, aims at supporting low-latency and energy-efficiency as well as security, self-adaptation, and spectrum efficiency by means of a strict collaboration among end-devices and FC+FN units in a same integrated platform. In addition, the development of suitable analytic methods and definition of appropriate techniques will enable extra relevant characteristics of the FC+FN platform including ubiquity, decentralized management, cooperation, proximity to end users, dense geographical distribution, efficient support for mobility and real-time applications. To achieve this goal, the GAUChO project foresees to address several relevant and challenging research topics that require skills and knowledge in different scientific fields. The scientific contributions that the project aims at achieving, are: i) efficient schemes for the coordinated management of resources and interference in heterogeneous wireless communication systems; ii) joint optimization of communication and computing capabilities to support energy-efficient management and self-reconfigurations; iii) a learning modality permitting software agents to detect variations within the integrated FC+FN platform; iv) model-free fault diagnosis systems and comprehensive methodology integrating intelligence-based mechanisms for optimally managing energy consumption, detecting changes in environment/system under inspection, and evaluating and mitigating the possible occurrence of faults affecting the end-devices computing units. The GAUChO project is expected to have a significant technological impact on many up-to-date and relevant families of technologies, such as Smart Wireless Sensor Networks (SWSNs), Smart Objects of Internet-of-Things and Intelligent Embedded Systems. All in all, the project will allow the FC+FN paradigm to enter into a new phase where real-world problems emerging from complex applications are addressed and effectively solved. It is expected that project outcomes will move from basic research to mass production in years 2018-25 providing significant economic benefits to masses of potential end users, together with the added value of the offered application services, limited cost of the communication and processing infrastructure.

Radio Access for the Internet of Things Traffic in Fifth-Generation Cellular Networks

Marco Centenaro

Abstract: In this talk, we deal with the fifth-generation (5G) cellular network as a fundamental enabling technology for massive machine-type communications (mMTC). 5G systems operate on licensed frequency bands, and exploit long-range wireless links and a star topology. Two contention-based radio access protocols designed in collaboration with Nokia Bell Labs Stuttgart are proposed, mathematically characterized, and compared against the current cellular standard (4G). The performance evaluation results show that the proposed protocols provide lower latency, higher throughput, and reduced downlink feedback thanks to their connectionless approach.

Bio: Marco Centenaro received the BSc degree in Information Engineering in 2012 and the MSc in Telecommunication Engineering in 2014, both from the University of Padova, Italy. From November 2014 until October 2017, he was a PhD student at the Department of Information Engineering of the University of Padova: during the doctoral course he carried out research on the support of massive Machine-to-Machine (M2M) traffic in heterogeneous networks and fifth-generation (5G) cellular systems. From September 2016 to December 2016 he was an intern at Nokia Bell Labs, Stuttgart, Germany; from January 2017 to July 2017 he was a visiting researcher at the Yokohama National University (YNU), Yokohama, Japan. Since November 2017, he is a postdoctoral research fellow at the Department of Information Engineering of the University of Padova, doing research on channel-state information signaling reduction in cellular networks based on frequency-division duplex (FDD).

 

 

Statistical Models for the Characterization, Identification, and Mitigation of Distributed Attacks in Data Networks

Mario Di Mauro

Abstract: The thesis focuses on statistical approaches to model, mitigate, and prevent distributed cyber-attacks. Three fundamental issues emerge distinctly. The first issue concerns the threat propagation across the network, which entails an "avalanche" effect, with the number of infected nodes increasing exponentially as time elapses. The second issue regards the design of proper mitigation strategies (e.g., threat detection, attacker's identification) aimed at containing the propagation phenomenon. Finally, in order to guarantee protection even when the attacker cannot be defeated, it is desirable to act on the system infrastructure to grant a conservative design through a controlled degree of redundancy. The presentation will focus on the first two aspects: i) with regard to the first issue, I will introduce Kendall's birth-and-death process as a powerful analytical model to deal with the cyber-threat propagation phenomenon; and ii) with regard to the second issue, I will present a rigorous statistical characterization for a novel kind of randomized Distributed Denial of Service (DDoS) attack, along with the analysis of a designedfrom-the-scratch algorithm for botnet identification.

 

 

Detection and motion parameters estimation techniques in Forward Scatter Radar

Nertjana Ustalli

Abstract: Forward Scatter Radar (FSR) systems exploit the extreme bistatic geometry, reached when thebistatic angle approaches 180°. FSR systems are receiving a renewed interest in the last years dueto their potentialities for the detection of low-observable targets (i.e. small targets or stealthtargets). This thesis reports on research into this field of radar systems with additionalcontributions to two broad areas: target detection and motion parameters estimation. The mainobjectives of this work were (i) the development of innovative techniques for target detectionjointly with the analytical characterization of the performance in terms of probability of false alarmand probability of detection, and (ii) the derivation of kinematic parameters estimation techniquesjointly with an accuracy analysis of the estimated parameters. During this talk, the main resultsreached with respect to these objectives will be discussed.
