  1. 1. Secure and Privacy Preserving Vehicular Communication Systems: Identity and Credential Management Infrastructure

    Författare :Mohammad Khodaei; Panos Papadimitratos; Tomas Olovsson; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Vehicular Communications; Security; Privacy; Access Control; Identity and Credential Management; Vehicular PKI; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Vehicular Communication (VC) systems can greatly enhance road safety and transportation efficiency. Vehicles are equipped with sensors to sense their surroundings and the internal Controller Area Network (CAN) bus. Hence, vehicles are becoming part of a large-scale network, the so-called Internet of Vehicles (IoV). LÄS MER

  2. 2. Mobile Satellite Broadcast and Multichannel Communications : analysis and design

    Författare :Cristoff Martin; Björn Ottersten; Jack Winters; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; communications; satellite broadcast; mobile; MIMO; asymptotic analysis; spatial multiplexing; Signalbehandling; Signal processing; Signalbehandling;

    Sammanfattning : In this thesis, analytical analysis and design techniques for wireless communications with diversity are studied. The impact of impairments such as correlated fading is analyzed using statistical models. Countermeasures designed to overcome, or even exploit, such effects are proposed and examined. LÄS MER

  3. 3. Sensor Data Sharing in V2X Communications : Protocol Design and Performance Optimization of Collective Perception

    Författare :Quentin Delooz; Andreas Festag; Alexey Vinel; Maben Rabi; Ana Aguiar; Högskolan i Halmstad; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; V2X; sensor data sharing; vehicular communications; Collective Perception; data congestion; Decentralized Congestion Control;

    Sammanfattning : Sensor data sharing involves exchanging sensor data among multiple devices, systems, or platforms through various means, such as wired or wireless communication, cloud storage, and distributed computing. In Vehicle-to-Everything (V2X) communication, sensor data sharing is known as Collective Perception (CP). LÄS MER

  4. 4. On Securing Vehicular Communications: Methods and Recommendations for Secure In-vehicle and Car2X Communications

    Författare :Nasser Nowdehi; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; V2X; in-vehicle network; vehicular communication; security; ETSI;

    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 and Vehicle to Infrastructure (together called V2X) communications. LÄS MER

  5. 5. Robust Vehicular Communications for Traffic Safety---Channel Estimation and Multiantenna Schemes

    Författare :Keerthi Nagalapur; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic Safety; Sector Antennas; All-to-all Broadcast; Channel Estimation; Cross-layer Pilot Scheme; Multiantenna Schemes; Vehicular Communications V2X ;

    Sammanfattning : Vehicular communications, where vehicles exchange information with other vehicles or entities in the road traffic environment, is expected to be a part of the future transportation system and promises to support a plethora of applications for traffic safety and efficiency. In particular, vehicle-to-vehicle (V2V) communication promises to support numerous traffic safety applications by enabling a vehicle to broadcast its current status to all the other vehicles in its surrounding.
