ICT Seminar “Characterizing control loops over Ultra-Reliable and Low-Latency Wireless Communication”

Speaker: Amal Alrish (PhD student at DISIM)
When: Thursday July 19, 2018, 15:30-16:00
Where: room 2.5 (Coppito 1, 2nd floor)
Title: Characterizing control loops over Ultra-Reliable and Low-Latency Wireless Communication

Abstract: The established wireless networking standards for industrial automation, WirelessHART and ISA-100 have been used widely for control and monitoring applications adopted in the previous years. However, they both rely on centralized network configuration and resource management that comes with large overhead for collecting network health information and disseminating routing graphs and transmission schedules to nodes, and the times required for a node to join a WirelessHART network can be substantial. Moreover, D2D communication cannot be supported by them because all data must pass through the gateway. Consequently, WirelessHART and ISA-100 are not suitable for the use in automated fast industrial process and robotics, which similarly to emerging cyber-physical applications in transportation, health-care, augmented reality support for maintenance works, virtual reality, education and culture that set high demands on underlying wireless connectivity solution. These applications require much more stringent requirements, such as low latency, high reliability and security, which warrant a paradigm shift from reactive and centralized networks towards massive, low latency, ultra-reliable and proactive networks. With the emergence of the fifth generation (5G) wireless networks, not only is the increase in mobile broadband targeted, but also the support of various previous mentioned used cases with ensuring ultra-reliable and low-latency communication (URLLC). The seminar will be focused on exploring new models supporting network slicing since it could be one of the appropriate solutions to meet the above mentioned requirements through allowing operator to partition network in a structured, elastic, scalable and automated manner

The talk is part of a series of seminars given by PhD students and researchers of our Department within the ICT area.
The goal of the seminars is to provide an overview on ongoing research activities, highlight common interests and explore emerging possibilities for collaboration between different research areas.

ICT Seminar “Integrated Simulation Environments for Vehicular Communications in Cooperative Road Transportation Systems”

Speaker: Arianna Persia (PhD student at DISIM)
When: Thursday July 19, 2018, 15:00-15:30
Where: room 2.5 (Coppito 1, 2nd floor)
Title: Integrated Simulation Environments for Vehicular Communications in Cooperative Road Transportation Systems

Abstract: Pervasive digital technologies and wireless communications are the key enablers for the “smart” evolution of transportation systems, where the current development trend is oriented to increase the level of safety and comfort in driving and traveling, to reduce CO2 emissions and to finally support assisted and autonomous driving. With particular reference to vehicular traffic, the accurate localization, pervasive connectivity and cybersecurity are expected to play a key role for the development of cooperative and intelligent transportation systems (C-ITS). In this frame the seminar proposes an overview of on-going research activities at the University of L’Aquila: moving from specific investigations on radio channel congestion control and mobility management applications, we then focus on methodologies and facilities for validation and testing through the combined use of simulation tools, emulation setups and field trials. The research activity is fully connected to a large scale project that deals with city-wide deployment and experimentation of 5G technologies in the city of L’Aquila, wherein the connected car has been presented as a relevant use case.

The talk is part of a series of seminars given by PhD students and researchers of our Department within the ICT area.

Seminar “Telecommunications Services and Network Architecture Evolution”

Speaker: Gianfranco Ciccarella (consultant on Telecommunication Strategy, IP Services and IP Networks)
When: June 26, 2018 — 10:30 am
Where: Meeting room (Alan Turing building)
Title: Telecommunications Services and Network Architecture Evolution

Abstract: The Telecommunications Industry scenario to date, the main drivers for the transformation and the target architecture for application services (the  services “used” by End Users) and network services (the services that provide the connectivity, i.e. the transport of the IP packets) are presented.
The focus is on
• why a disruptive Telecommunications Industry transformation is needed
• the main Telecommunications Industry issues (Time to Market, Total Cost of Ownership, application services performance and Ultra Broad Band monetization)
• how to address the Telecommunications Industry issues
• the application and network services target architecture.
The target scenario is
• All IP: one single IP Telecommunications Network  able to provide the performance required by any application service
• Edge Cloud Computing based: application services, content delivery and network functions/services are executed in ‘Telco Data Centers’ distributed over different layers: core, regional and edge (i.e. central office or Cloud Radio Access Network).
Edge Cloud Computing, as reported in ETSI, GPP and GSMA documents, celebrates first successes and is able to provide
• quality improvements (i.e. technical KPIs improvement), that enable new revenues
• cost savings, in many cases, for services and network costs
due to the distribution ‘near’ the end users (i.e. as deep into the network as needed by services requirements and cost saving opportunities) of
• some of the IP Edge functionalities. The distribution of IP Edge functionalities enables the distribution of services, applications and content delivery platforms.
• services, applications, contents and content delivery platforms.
Distribution technologies (NFV and Cloud) are available, however many challenges have still to be addressed to solve the main issues related to the Telecommunication Industry vision on services and network.
Some comments on this points are presented.
Data on application performance improvement and network TCO saving provided by the the target architecture are also given.

Gianfranco Ciccarella is a former Associate Professor at University of L’Aquila and a brillian consultant on Telecommunication Strategy, IP Services and IP Networks. This will be a great chance to gain a new perspective on Telecommunication Network Architectures, especially considering the ongoing activities that involve our university such as the Italian 5G trial and the INCIPICT and EMERGE research projects.

 

ICT Seminar “Modeling and performance analysis of advanced detection architectures for ADS-B signals in high interference environments”

Speaker: Sandro Chiocchio (PhD student at DISIM)
When: Thursday July 5, 2018, 15:00-15:30
Where: room 2.5 (Coppito 1, 2nd floor)
Title: Modeling and performance analysis of advanced detection architectures for ADS-B signals in high interference environments

Abstract: The RTCA (Radio Technical Commission for Aeronautics) DO-260B document has stimulated in latest years the adoption of novel algorithms to improve the ability of receivers to detect and decode ADS-B signals, with particular emphasis on preamble detection, declaration of bit state and confidence level, detection and correction of errors. This work reports on performance analysis of a set of enhanced techniques that we have developed for detection and decoding of ADS-B signals transmitted on 1090 MHz carrier frequency in high interference conditions.  An extensive set of results has been derived through a specifically developed simulation environment, able to closely model a wide range of operational scenarios by generating ADS-B frames and Mode A/C interfering signals. The simulation environment also includes a detailed implementation of the features of both linear and logarithmic amplifier stages in the RF receiver architecture. The investigations are mainly focused on evaluating the impact of the interference generated by Mode A/C replies on preamble detection and data decoding for ADS-B signals. In this regard, the ability of enhanced reception techniques to improve detection performance is assessed. Numerical results obtained from extensive simulation runs are reported and commented. They actually demonstrate that enhanced techniques are essential to guarantee adequate detection performance in the harsh environments envisaged by increased intensity of air traffic and extensive use of ADS-B for traffic control.

ICT Seminar “Performance Evaluation of Cooperative Communications over Fading Channels in Vehicular Networks”

Speaker: Caslav Stefanovic (visiting postdoc)
When: Thursday June 21, 2018, 15:00-15:30
Where: room 2.5 (Coppito 1, 2nd floor)
Title: Performance Evaluation of Cooperative Communications over Fading Channels in Vehicular Networks

Abstract: This seminar provides channel modeling and performance evaluation study of vehicle-to-vehicle (V2V) and  vehicle-to-infrastructure (V2I) cooperative communications in urban non-line-of-sight (NLOS) multipath fading environments.
The proposed model investigates three different scenarios: i) V2V communications enabled by parallel cooperative dual-hop amplify-and-forward (AaF) vehicle-relaying, ii) V2V communications enabled by dual-hop AaF road-side-unit (RSU) relaying on one link and direct V2V communications on another link, iii) V2I communications enabled by dual-hop AaF vehicle-relaying on one link and direct V2I communications on another link. We derive relevant statistics  for the output signal envelope and related system performance, e.g. the level crossing rate and average fade duration for  varying outage threshold. Numerical results are presented for different sets of channel parameters.

ICT Seminar “Analysis and Experimental Characterization of Channel Congestion Control in Vehicular Networks”

Speaker: Elena Cinque (postdoc research fellow at DISIM)
When: Thursday June 14, 2018, 15:00-15:30
Where: room 2.5 (Coppito 1, 2nd floor)
Title: Analysis and Experimental Characterization of Channel Congestion Control in Vehicular Networks

Abstract: Vehicular communication technologies are the enabling factor for development of smart mobility applications. Current solutions proposed by standard organizations support short and medium range communications, based on IEEE 802.11p for delay-sensitive applications and on cellular networking for integrated data management over large areas. This distinction could be overcome by the unifying paradigm of 5G. Mobility services require a continuous exchange of awareness messages among vehicles and road infrastructure elements, mainly for safety applications.
Whatever communication technology is used, a basic requirement for the effectiveness and reliability of safety applications is the radio channel availability for dissemination of information among network elements.
In this seminar we describe our ongoing activities of study, analysis, and experimentation about channel congestion evaluation and control strategies, relying both on real devices and simulation environments. The proposed framework of tools and current activities can provide a good base for modeling complex urban scenarios in a perfect context for testing, like the city of L’Aquila, that aims at being reconceived as a modern smart city, and has been selected for 5G experimentation.
