Title: Collision Resolution Protocol for Delay and Energy Efficient LoRa Networks

Abstract:
Future 5G and Internet of Things (IoT) applications will heavily rely on long-range communication technologies such as low-power wide area networks. In particular, LoRa enables a communication range of 5-20 km with a bitrate of a few kilobits per second. In the event of collisions, the perceived rate is further reduced. In this talk, we present how the specific features of LoRa can be used to decode slightly-desynchronized superposed signals. Our results show that this technique can improve the throughput of LoRa, and thus increases the use cases for this technology.

Title: Localized Interactions for an Open Urban ITS Ecosystem

Abstract:
A revolution will come from the edge of the Internet, almost everything will be able to communicate and to interact with its environment to perform various tasks. From the pervasive computing envisioned just a few years ago, in which small computers are spread in the environment, the vision of the Internet of Things evolves towards a world where objects have very different characteristics. Applications and services have to take this into account to be able to meet requirements that could be strong when human life is in danger (vehicular communication, industrial IoT, eHealth). They also have to adapt their behavior to the context in which they operate.

Pervasive applications and services ready to be deployed and to operate in various environments should overcome the existing silos and allow significant cost reduction. The collection and construction of a reliable and relevant perception of the environment is necessary for many decision algorithms proposed in various domains. Adapting the behavior of the environment to the actual requirements of such decision making mechanisms is a challenge. In our vision, the lack of resources by which properties of the real environment are made available to application developers is a major concern. Exposition of raw sensor values to the decision-making process does not allow to build relevant perception that a pervasive application actually needs in order to shrewdly act/react to changes in the environment.

Bio:
After a PhD degree in computer science at the university of Strasbourg in 1998, I came to ENST Bretagne for a research position. I am currently professor (HDR) at IMT Atlantique and the leader of the Inria/EASE research team.

Since 2001, I have been mainly interested in the convergence between IP networks and mobile telephony networks, and therefore in heterogeneous handover management. More recently, I have been involved in projects dealing with the mobility of the networks and its application to ITS (Intelligent Transportation System). Currently, I am interested in how to provide pervasive applications with a good perception of their environment through localized interactions. More specifically I am interested in cooperative autonomous vehicles.

I am cofounder and scientific advisor of the YoGoKo startup which provides communication solutions for cooperative ITS (Intelligent Transport Systems) including autonomous vehicles.

I lead the program committee of the InOut event (inout.rennes.fr) since the first edition in 2018. The InOut initiative aim at thinking the future of the Mobility with users and stakeholders.

Title: Power Laplacian Graph-Semi Supervised Learning for Autonomous System Identification

Abstract:
Autonomous System (AS) identification is a crucial stake in Internet routing and monitoring. While TraceRoute measurements provide relevant information regarding internet graph topology and IP prefixes, BGP data remain prone to error in attributing nodes at the border between AS to the correct AS. Power Laplacian Graph-Semi Supervised Learning permits to combine graph topology and « expert information » for Autonomous System Identification. The present talk will review PageRank based graph semi-supervised leaning and its extension to power laplacians for classification. It will be shown that an optimal power can be estimated directly from available data. The potential of the Power Laplacian Graph-Semi Supervised Learning for Autonomous System Identification will be illustrated at work on a small but real Internet graph.

Abstract:
In addition to be connected, the vehicle of tomorrow will cooperate with the surrounding environment. In order to improve road safety, traffic efficiency and for numerous value added services, vehicles will exchange data with other vehicles and other road users, the roadside and the urban infrastructure, service providers and control centers. All these services have different communication requirements and constraints in terms of communication range, volume of data, delay, quality of service, security. No single access technology is able to fulfill all these requirements at once. In addition, regulation, density, regions and available radio spectrum lead to different deployment of access technologies and protocols. However, most vehicles move away from any designated geographic area and must be able to maintain connectivity and exchange data with their surrounding environment anywhere, anytime with anyone. This talk provides an insight into Cooperative ITS (C-ITS) standards developed by ISO (International Organization for Standardisation) within Technical Committee 204 dedicated to ITS. The development of a harmonized, open, functional, future-proof and silo-free architecture – known as the ITS station architecture – started in 2002. This architecture is designed to easily integrate existing technologies. As such the ITS station communication and data architecture combines multiple access technologies and protocols offering both localized communications (V2X, sensors networks, …) and networked communications (cellular, …). C-ITS standards developed around the ITS station architecture cover access technologies (ITS-G5, DSRC, cellular, infra-red, satellite, visible light, sensor networks, …), communication protocols (IPv6 and non-IP), common facilities services (V2X messaging, precise positioning, local dynamic map, data management, …), security and management services. While the most advanced of these standards are still under development, Cooperative ITS services compliant with the ITS station architecture are being deployed everywhere in Europe (SCOOP in France, Nordic Way in Scandinavia, C-Roads and InterCor elsewhere in Europe).

He then worked at Keio University in Japan (2002-2006) where he performed research activities on Internet technologies related to Intelligent Transport Systems (ITS) under the direction of Prof. Jun Murai. Following his advices, he set up and led the Nautilus working group within the WIDE organization. In the meantime, he also launched and led the NEMO and the MonAmi6 working groups at the IETF (Internet Engineering Task Force). Back to France, he started to work in research labs specialized in autonomous driving (Inria 2006-2010 and Mines ParisTech 2010-2015) where he was appointed to develop a communication architecture for connected, cooperative and autonomous vehicles. As such, he coordinated research and participated in several ITS-related European Projects and coordinated two of them (GeoNet, ITSSv6). He first got involved in ITS-related standardization activities in 2002 and actively contributed to the development of several standards for Cooperative ITS technologies and services in the ISO (TC 204), CEN (TC 278) and ETSI (TC ITS) standards organizations. His coordination of R&D projects and his participation to standards organizations were an important step towards the setup of the YoGoKo company and its success in developing advanced technology solutions for the connected autonomous vehicle.

Title: Modular Active Environment for Mobile Robots and Tamper-resistant Communication

Abstract:
Resilient and secure distributed agreement is the cornerstone of distributed systems and, although it takes many forms, this is also true with IoT (Internet of Things) and CPS (Cyber-Physical Systems). In this talk, we will focus on one application context of cyber-physical systems, namely the problem of pickup and delivery by multiple robots in a shared environment. We will briefly discuss priority-based heuristics for multi-agent path-finding, and then present our prototype of a modular active environment for robot navigation and raise some of the needs for resilience and security that it entails.

Title: Energy-Efficiency Optimization in Fog Radio Access Networks

Abstract:
In order to satisfy the stringent latency requirements envisioned for 5G and beyond applications, the concept of Fog Radio Access Networks (FRAN) has recently emerged for providing cloud computing at the edge of the network. Although FRAN may alleviate the latency and user Channel State Information (CSI) quality issues of Cloud Radio Access Networks (CRAN), its distributed nature degrades network interference mitigation and global system performance. Therefore, we investigate the design of tailored user scheduling and beamforming for FRANs. In particular, we investigate the issue of global energy efficiency optimization, under the local user clustering constraint specific to FRANs. We first propose an optimized algorithm that requires high computational complexity. Next, we propose a low-complexity heuristic algorithm taking advantage of the FRAN architecture. Computer simulation results that our proposed algorithm outperforms the baseline algorithm even under imperfect CSIs, while achieving a good performance compared to the optimized solution.

Title: Roadside cooperative perceptionfor autonomous vehicles

Abstract:
Cooperative Intelligent Transportation Systems (ITS) are systems where the vehicles, the roadside infrastructure, central control centres and other elements exchange information to achieve better road safety, traffic efficiency and comfort of the road users. These cooperative elements share the information by organising Vehicular Ad-hoc Network (VANET) or using the mobile network (e.g. 3G and LTE) and realises various cooperative ITS services. To promote wider deployment of such services, many stakeholders made consensus that the communication platform must be based on a common architecture and drive rapid international standardisation (e.g. ISO, ETSI, IEEE). In the near future, autonomous vehicles also benefit from such communication platforms by enforcing the perception, planing, and decision-making. However the most basic Vehicle-to-Vehicle (V2V) messages standardized in Europe, US and Japan suffer from same issues such as 1) unable to receive messages from the object without V2V transmitter, 2) message loss because of obstacle and wireless range, 3) vulnerable for malfunctioning and malicious node. For the solution, we propose an infrastructure-assisted V2V messaging system to support cooperative autonomous driving. We design the system based on the ITS Station architecture standardized in ISO/ETSI, working with any vehicle sensing technology. Moreover, we implement the prototype roadside system with a stereo vision for the vehicle sensing. The prototype system is evaluated in a field test in the campus of the University of Tokyo. The results show that the proposed system significantly improves the coverage of V2V messaging while the system overhead is limited. The proposal is being integrated to our personal mobility autonomous vehicle system based on an open source software. We are also planning the contribution to the international standardization of the technique.

Title: AS Hegemony: Measuring AS inter-dependency

Abstract:
Autonomous Systems (ASes) connected to the Internet are inherently relying on other ASes to transmit data. Identifying these AS inter-dependencies assists network operators and researchers in understanding the current state of the Internet, monitoring changes, and improving connectivity. In this presentation we introduce, the basics of AS Hegemony, a graph centrality metric estimating the AS inter-dependencies from BGP data. Then we will present numerous applications, such as, quantifying Internet flattening, assessing the impact of new deployments, detecting routing anomalies, and topological changes due to geopolitical events.

Title: Outing IXPs networks from the complexity spiral

Abstract:
IXPs are central elements of the Internet ecosystem. IXPs carry substantial traffic volumes and interconnect a multitude of diverse networks. Like many others, IXP networks fall into the “complexity/robustness spiral.” (i.e., robust design → complexity → new fragility → make new design more robust → …) that—without faith in a reliable and ideal architecture—can easily and quickly get out of control. Moving the complexity in the upper management layers has been recognized as the best solution to reduce cost and risk without mitigating scalability.

Taking into account the specific IXP networks context, We propose to change drastically the way IXP operators will design and manage their networks. Diagraming is commonly the last step of any networking project. We have identified diagraming as the central task for IXPs network change.

Our design proposal applies existing best practice provisioning, followed by a Zero-Touch “Drag and Drop” network planning and design. For this, we decided to enhance IXP-Manager with the Umbrella OpenFlow architecture supported by the FAUCET controller.

IXP Manager is a complete Open Source management system for IXPs, which includes an administration and customer portal; provides end to end provisioning; and both teaches and implements best practice.
Umbrella is OpenFlow switching fabric architecture explicitly developed for IXPs. Umbrella has been deployed in 2015 and operating since then at Toulouse IXP and in recently at Osaka NSP-IXP3.

Title: Transmission of knowledge and influence in complex networks

Abstract:
In information network (a graph with nodes that generate and transmit a flow of information), knowledge is transmitted differently than classical flow. The complexity of computation comes from arbitrary properties such as equity, moral, the value of knowledge, temporal component. However, at the opposite of classical flow models, its structure allows for efficient to “decycle” the network and obtain accurate linear time computation.
We introduce the fundamental concepts of this work with classical graphs, but it can be easily extended to most of the more complex networks such as multiplex networks or temporal networks. We also address the fairness issue coming from versioning. That is how to evaluate the amount of information brought by each new version.

Title: The Quantum Internet

Abstract:The Quantum Internet will transform how we communicate, compute and measure our universe. Using long-distance entanglement, we can execute cryptographic functions that strengthen the security of classical communications, measure physical phenomena more precisely than purely classical systems, and ultimately couple quantum computers together to extend the size of problems they can solve. But how can we build such a network? Experimental progress toward quantum repeaters — the quantum equivalent of the Internet’s switches and routers — is moving at a dizzying rate, and theorists have proposed half a dozen approaches to managing errors to create high-fidelity entanglement along a chain of repeaters. The next frontier is extending from one-dimensional chains to complex topologies, and on to a network of networks — a true Quantum Internet. In this talk, I will bridge the physics and the engineering to give a picture of the current status and open research problems.

Title: A Strategy of the telecom network convergence using SRv6

Abstract: The telecom carrier network architecture has gradually changed from circuit-oriented to packet-oriented to be scale-free and its abstraction. PTN(Packet Transport Network) such as MPLS-TP has converged existing specific network media, SDH, ATM, Frame Relay and so on. At the same time, the mobile network specification such as 3GPP has also made concessions to packet-oriented network. 3G allowed to use IP network for data communication instead of ATM, 4G allowed VoLTE which is a voice service over IP network. However, some encapsulation technologies that establish the virtual circuit over the unified IP network are remaining. For example, GTP-U is a circuit emulation technology to deliver the mobile user plane traffic between the mobile anchor and base stations. Those kinds of technology are not only unconforming to the routing policy, but also unsuitable for upcoming MEC(Multi-access Edge Computing) and/or WWC(Wireless and Wireline Convergence) era. This presentation shares the current issues of the telecom carrier network architecture toward MEC and WWC, and proposes a strategy of how we can converge all network resources using SRv6.

Title: Causal Analysis of Network Log Events

Abstract:
To detect root causes of failures in large-scale networks, we need to extract contextual information from operational data automatically. Correlation-based methods are widely used for this purpose, but they have a problem of spurious correlation, which buries truly important information. We present a method for extracting contextual information from network logs by a graph-based causal inference algorithm. Through the causal analysis results and case studies in the network logs collected from SINET, we demonstrate the effectiveness of the proposed method for practical network operation.

Title: An Experiment of SRv6 Service Chaining at Interop Tokyo 2019 ShowNet

Abstract:
ShowNet is one of the largest event networks that demonstrates the latest network technologies while providing network connectivity to the exhibitors and visitors in Interop Tokyo. Interop Tokyo is also one of the largest network technology exhibitions held in Japan.
In ShowNet 2019, we designed and deployed a Segment Routing IPv6 (SRv6)-based service chaining network as a critical network infrastructure of the ShowNet backbone. SRv6 is still a state-of-the-art routing protocol; therefore, we faced some issues to practically design and operate such an SRv6-based network. In this session, we describe the design of SRv6-based service chaining and practical knowledge learned from its operation in ShowNet 2019.
