  2. 16. Performance evaluation of safety critical ITS-G5 V2V communications for cooperative driving applications

    Author : Nikita Lyamin; Alexey Vinel; Magnus Jonsson; Boris Bellalta; Geert Heijenk; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; C-ITS; VANET; ITS-G5; IEEE 802.11p; ETSI; platooning; C-ACC; jamming Denial-of-Service attack; congestion control; cooperative awareness; security in C-ITS;

    Abstract : Intelligent Transport Systems (ITS) are aiming to provide innovative services related to different modes of transport and traffic management, and enable various users to be better informed and make safer, more coordinated and smarter use of transport networks. Cooperative-ITS (C-ITS) support connectivity between vehicles, vehicles and roadside infrastructure, traffic signals as well as with other road users. READ MORE

  4. 17. On design of dependable communication protocols for wireless sensor networks

    Author : Laurynas Riliskis; Marko Hännikäinen; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dependable Communication and Computation Systems; Kommunikations- och beräkningssystem;

    Abstract : This thesis considers a problem of a design of dependable communication protocols for wireless sensor networks. In life critical applications of sensor networks, for example, connected to protection of critical infrastructures or intelligent transportation system dependability (i.e. READ MORE

  5. 18. Enhancing the Maintainability of Safety Cases Using Safety Contracts

    Author : Omar Jaradat; Sasikumar Punnekkat; Iain Bate; Alexander Romanovsky; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

    Abstract : Safety critical systems are those systems whose failure could result in loss of life, significant property damage, or damage to the environment. These systems require high quality and dependability levels in them, where system safety is a major property that should be adequately assured to avoid any severe outcomes. READ MORE

  6. 19. Availability Analysis of Frequency Converters in Electrified Railway Systems

    Author : Yasser Ahmed Mahmood; Hoang Pham; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance Engineering;

    Abstract : The increased interest in electrified railways can be explained by their huge capacity, high efficiency, and low pollution. Today’s electrified railway is expecting higher demands for electric power for increased speeds, increased traffic volume capacity, and heavier freight loads. READ MORE

  7. 20. On the Design and Validation of Fault Containment Regions in Distributed Communication Systems

    Author : Håkan Sivencrona; RISE; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fault handling and membership agreement; Byzantine faults; asymmetric faults; fault injection; time-triggered protocol; fault containment regions; slightly-out-of-specification faults; validation;

    Abstract : This thesis has a two fold focus where the first is an evaluation of a time-triggered communication protocol implementation, TTP-C1, which was stressed by use of heavy-ion fault injection. The gathered result showed a novel type of failures, earlier known only from theory, so-called slightly-out-of-specification faults, that manifested as Byzantine failures with resulting system inconsistence.
