Title: "Impact of transmission cost on Age of Information at Nash
equilibrium in random-based medium access
"

Talk. C3-005, Campus Nord (UPC). 

Also online:https://meet.google.com/tvx-wahz-hte

Abstract: Random-based medium access protocols are often considered inefficient and unstable from a game theoretic perspective, because the players (i.e., the transmitters) want to maximize their individual utility and so they tend to be very aggressive, which causes collisions. Generally, this is limited by introducing a cost for the transmission. However, if each player's objective is high throughput, the aggressiveness is only partially limited as the resulting equilibrium is inefficient. We show that, if the objective shifts to age-of-information, the resulting equilibrium can become more efficient. Interesting, this has some simple analytical formulation in basic protocols like slotted ALOHA, but becomes still valid in more advanced techniques where irregular-repetition or capture-effect are inserted.

"Talk on 5G: technology and security"

Speaker: Dr Jordi Mongay Batalla (Univ. Warsaw, Poland)

C3-005, Campus Nord (UPC). 

Also online:  https://meet.google.com/fgb-usnn-bxz

Abstract:  In the next years, 5G will introduce hundreds of new services and applications, which will benefit from the advanced features of the 5G network. The new scenarios foreseen in 5G are: (1) Ultra Reliable Low Latency Communications (URLLC) including applications with strict requirements on latency and reliability for mission-critical communications, such as remote surgery, autonomous vehicles or the tactile Internet; (2) Enhanced Mobile Broadband (eMBB) which includes data-driven use cases requiring high data rates across a wide coverage area; and (3) Massive Machine Type Communications (mMTC) which support a very large number of devices in a small area that may only send data sporadically, such as Internet of Things (IoT) use cases.

5G is a new network that is currently being developed and implemented. This offers the possibility of approaching security not only as a response to threats, but also from the moment of designing the network and starting the development of the elements of the network. However, before approaching security in the 5G, we should recognise that a completely secure network will never be possible…Bio: JordiMongay Batalla (MSc by Polytechnic of Valencia, Spain; PhD and DSc by Warsaw University of Technology, Poland. ORCID: 0000-0002-1489-5138) was born in Barcelona (Spain). He obtained M.Sc. degree from Universitat Politècnica de Valencia in 2000 and Ph.D. and habilitation degrees from Warsaw University of Technology in 2009 and 2017, respectively. In past, he worked in Centro Nazionale di Astrofisica in Bologna (Bolonia, Italy), where he conducted research on Diffserv networks, in Telcordia Poland, an Ericsson R&D Co. (Poznań, Poland), where he provided research on Vulnerabilities Management of IPv6 and Risk Assessment for IPv6 Ready; as well as in Seidor S.A. (Barcelona, Spain), in charge of European R&D projects in the field of cybersecurity enforcement. He is now with National Institute of Telecommunications, one of the largest scientific research institutions in Poland, where from 2018 he is the Deputy Director of Research. He is also with Warsaw University of Technology, where he is an Associate Professor in the Department of Computer Network and Services.

Currently Prof. Mongay Batalla is an adviser in different international and national technical groups. He is a technical adviser of the Polish Government for 5G cybersecurity law, a technical adviser of Polish Ministry of Infrastructure for autonomous automotive and others. Jordi Mongay is a Non-CEI expert of the European Union Agency for Cybersecurity (ENISA) for 5G cybersecurity. He is also a technical member of the European Blockchain Services Infrastructure (European Commission) and is a member of Hyperledger platform (a TheLinuxFoundation project). He is Member of the Polish Normalization Committee and collaborates actively with ITU-T Standardisation Groups (SG-12). He is an IEEE and ACM Member since 2010.

His research interest focuses mainly on Cybersecurity (Risk Assessment, Security Enforcement, Vulnerabilities Management), IP Technologies (radio: 5G and 6G, core: Network services chain, SDN, AI) and Applications (DLT and blockchain, Internet of Things, Smart Cities, multimedia) for the Future Internet.

Jordi Mongay Batalla took part (coordination and/or participation) in more than 30 national and international ICT research projects (including EU ICT Programs). He is editor of four books and author of more than 150 papers published in books, international journals (IEEE ComMag, IEEE WCM, IEEE JSAC, ACM CSUR, etc.) and conference proceedings and two patents (Polish and European Patent Offices). He is/ has been guest editor and member of Editorial Board in more than 10 international journals. He is also interested in human sciences, especially psychology and social sciences, where he finished two postgraduate courses.

Talk: "An NFV system to support service provisioning on UAV networks”

- Speaker: Borja Nogales, from UC3M.

Where: Classroom C4-021B and meet.google.com/nvc-qepq-axz

 

_________________________________________________________________

Abstract: We will describe the design an implementation of an NFV system capable of deploying moderately complex network services over a wireless ad-hoc network of resource-constrained compute nodes. The system design targets aerial networks built by Unmanned Aerial Vehicles (UAVs), and it relies on container virtualization to support the execution of network functions within constrained environments, as well as on mobile ad-hoc networking to support the underlying end-to-end network communications. The presentation will also cover the implementation experience from developing this NFV system, which is based on relevant and widely-adopted open-source technologies in the NFV arena such as ETSI Open-Source MANO (OSM) and OpenStack. In addition, we will present the integration of this system into a distributed NFV testbed spanning three different remote sites in Spain, i.e., Universidad Carlos III de Madrid (UC3M), Universitat Politècnica de Catalunya (UPC), and Universidad del País Vasco (UPV-EHU). The goal of this testbed is to explore synergies among NFV, UAVs, and 5G vertical services, following a practical approach primarily governed by experimentation.

Title: "Multi-agent navigation of autonomous vehicles and parking problems"

Talk. C3-005, Campus Nord (UPC).  Also online: https://meet.google.com/fgb-usnn-bxz

PDF of the talk:  https://drive.google.com/file/d/1Kd6mEsZWooscvEarqofRP4aZuIOpADzK/view?usp=sharing

_________________________________________________________________
Abstract:  Intelligent autonomous vehicles navigating in a smart city environment need to find a parking spot, but the task of efficiently using parking resources is at odds with the selfish nature of competing agents. If we model the problem through game theory, we can evaluate the efficiency of a distributed decision mechanism. At the same time, we also gain insight on the complexity of identifying efficient solutions and hint that the overall problem is difficult to solve without compromising the inherent selfish objective of each individual vehicle.

Title: "A Game of One/Two Strategic Friendly Jammers Versus a Malicious Strategic Node"

Abstract: This talk presents some research applications in the context of friendly jamming, where jamming is performed by the legitimate network to defeat a malicious transmitter. We will see how game theory is able to find interesting and sometimes counterintuitive behaviors when analyzing this jamming problem in the presence of one or multiple jammers.
