  1. 21. Automotive Communication Security Methods and Recommendations for Securing In-vehicle and V2X Communications

    Författare :Nasser Nowdehi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; V2X; security; automotive; vehicular communication; in-vehicle network;

    Sammanfattning : Today’s vehicles contain approximately more than 100 interconnected computers (ECUs), several of which will be connected to the Internet or external devices and networks around the vehicle. In the near future vehicles will extensively communicate with their environment via Vehicle to Vehicle (V2V) and Vehicle to Infrastructure (V2I), together called V2X communications. LÄS MER

  3. 22. Communication and Networking Techniques for Traffic Safety Systems

    Författare :Ioan Chisalita; Nahid Shahmehri; Shie-Yuan Wang; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicular communication; networkking; safety-data; Telecommunication; Telekommunikation;

    Sammanfattning : Accident statistics indicate that every year a significant number of casualties and extensive property losses occur due to traffic accidents. Consequently, efforts are directed towards developing passive and active safety systems that help reduce the severity of crashes, or prevent vehicles from colliding with one another. LÄS MER

  4. 23. A Structured Approach to Securing the Connected Car

    Författare :Pierre Kleberger; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; vehicular services; connected car; remote diagnostics.; security mechanisms;

    Sammanfattning : Vehicles of today have become increasingly dependent on software to handle their functionalities. Updating and maintaining the software in vehicles has therefore become a costly process for the automotive industry. LÄS MER

  5. 24. Communications-Oriented Modeling and Development of Vehicular Distributed Embedded Systems

    Författare :Saad Mubeen; Mikael Sjödin; Jukka Mäki-Turja; Petru Eles; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Embedded systems; real-time systems; distributed embedded systems; component-based development; End-to-end timing analysis; response-time analysis; Controller Area Network; component model; timing model; Computer Science; datavetenskap;

    Sammanfattning : The model- and component-based development approach has emerged as an attractive option for the development of vehicular distributed real-time embedded systems. Within this context we target challenges related to modeling of legacy network communication, extraction of end-to-end timing models and support for end-to-end timing analysis. LÄS MER

  7. 25. Bit-Wise Decoders for Coded Modulation and Broadcast Coded Slotted ALOHA

    Författare :Mikhail Ivanov; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mutual information; vehicular communications; bit-interleaved coded modulation; error floor; slotted ALOHA; medium access control; All-to-all broadcast;

    Sammanfattning : This thesis deals with two aspects of wireless communications. The first aspect is about efficient point-to-point data transmission. To achieve high spectral efficiency, coded modulation, which is a concatenation of higher order modulation with error correction coding, is used. LÄS MER
