   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CSMA; self-organizing TDMA; STDMA; medium access control; MAC; vehicular ad hoc networks; VANET; vehicle-to-vehicle communications; V2V; V2X; IEEE 802.11p; WAVE; DSRC; ETSI ITS-G5; ISO CALM M5; real-time communications; scalability; traffic safety; cooperative system; Datatransmission; Datatransmission;

   Sammanfattning : This licentiate thesis work investigates two medium access control (MAC) methods, when used in traffic safety applications over vehicular ad hoc networks (VANETs). The MAC methods are carrier sense multiple access (CSMA), as specified by the leading standard for VANETs IEEE 802. LÄS MER

3. 12. Enhancing Localization, Selection, and Processing of Data in Vehicular Cyber-Physical Systems

   Författare :Bastian Havers; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicular Cyber-Physical Systems; Stream Processing; Edge-to-Cloud Continuum; Provenance; Distributed Data Analysis;

   Sammanfattning : Connected devices on the edge of the Edge-to-Cloud (E2C) continuum are producing increasing amounts of data that hold the key to unlocking valuable use cases among a wide range of applications. In the vehicular domain, connected vehicles in large fleets (called Vehicular Cyber-Physical Systems or VCPSs) sense and collect terabytes of data such as time series and video, enabling everything from predictive maintenance to autonomous drive.

4. 13. Distributed and Communication-Efficient Continuous Data Processing in Vehicular Cyber-Physical Systems

   Författare :Bastian Havers; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Query Spreading; Data Streaming; Vehicular Cyber-Physical Systems; Compression; Edge Computing;

   Sammanfattning : Processing the data produced by modern connected vehicles is of increasing interest for vehicle manufacturers to gain knowledge and develop novel functions and applications for the future of mobility. Connected vehicles form Vehicular Cyber-Physical Systems (VCPSs) that continuously sense increasingly large data volumes from high-bandwidth sensors such as LiDARs (an array of laser-based distance sensors that create a 3D map of the surroundings).

5. 14. Reusability of Software Components in the Vehicular Domain

   Författare :Mikael Åkerholm; Ivica Crnkovic; Kristian Sandström; Lars Grunske; Mälardalens högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Software Engineering; Embedded Systems; Computer science; Datavetenskap; Datavetenskap;

   Sammanfattning : Component-based software engineering is concerned with enabling software to be assembled through systematic (re)use of carefully built software elements denoted components. In this thesis we describe how reusability benefits of component-based software engineering can be utilized for organizations acting in the vehicular domain. LÄS MER

7. 15. On the Design and Analysis of Consensus Protocols for Vehicular Ad Hoc Networks

   Författare :Negin Fathollah Nejad Asl; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicular Ad-Hoc Networks; Intelligent Transportation Systems; Probabilistic Analysis; Communication Failure; Agreement Algorithms; Consensus;

   Sammanfattning : Vehicle-to-vehicle communication technologies support diverse cooperative applications for intelligent transportation systems to increase safety and fuel efficiency of road vehicles. Vehicles participating in a cooperative pplication are expected to make coordinated and mutually consistent decisions. LÄS MER
