  1. 1. Evaluation and Optimization of LTE-V2X Mode 4 under Aperiodic Messages of Variable Size

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Md Mamunur Rashid; [2023]
    Nyckelord :LTE-V2X; aperiodic; variable size; CAM; Technology and Engineering;

    Sammanfattning : Vehicular networks connect vehicles for improved road safety and efficiency with the assistance of wireless information exchange. Vehicular networks are based on the frequent broadcast of awareness messages referred to as CAM (Cooperative Awareness Messages) or BSM (Basic Safety Message) in the ETSI and SAE standards, respectively.

  3. 2. Cooperative Beacon Rate Adaptation for Vehicular Ad-hoc Network

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jinru Li; [2021]
    Nyckelord :;

    Sammanfattning : In Vehicular Ad-hoc Networks (VANETs), the vehicles need to periodically exchange current mobility status information with neighboring vehicles through beacon messages. The mobility status includes, among others, speed, position, and direction of the vehicle, which help vehicles to keep awareness of neighboring vehicles for better traffic efficiency and safety.

  4. 3. A Cloud-native Vehicular Public Key Infrastructure : Towards a Highly-available and Dynamically- scalable VPKIaaS

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Hamid Noroozi; [2021]
    Nyckelord :Security; Privacy; Vehicular PKI; VPKI; Identity and Credential Management; Vehicular Communications; VANETs; Availability; Scalability; Resilient; Efficiency; Microservice; Container Orchestration; Cloud; Pseudonym Transition; Pseudonym Unlinkability.; Säkerhet; personlig integritet; identitet- och behörighetsuppgifter; tillgänglighet; skalbarhet; motståndskraftig; effektivitet; moln; pseudonymitet; anonymitet; ospårbarhet.;

    Sammanfattning : Efforts towards standardization of Vehicular Communication Systems (VCSs) have been conclusive on the use of Vehicular Public-Key Infrastructure (VPKI) for the establishment of trust among network participants. Employing VPKI in Vehicular Communication (VC) guarantees the integrity and authenticity of Cooperative Awareness Messages (CAMs) and Decentralized Environmental Notification Messages (DENMs).

  5. 4. Efficient, Scalable and Secure Vehicular Communication System : An Experimental Study

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Shubhanker Singh; [2020]
    Nyckelord :Vehicular Public-Key Infrastructure VPKI ; Vehicular Communication VC ; Beacon; Pseudonymous Certificate PC ; TESLA; Signature Verification; Cooperative Verification; Fordonsinfrastruktur med allmän nyckel; Fordonskommunikation; Beacon; Pseudonymt Certifikat PC ; TESLA; Signatur Verifiering; Kooperativ Verifiering;

    Sammanfattning : Awareness of vehicles’ surrounding conditions is important in today’s intelligent transportation system. A wide range of effort has been put in to deploy Vehicular Communication (VC) systems to make driving conditions safer and more efficient. Vehicles are aware of their surroundings with the help of authenticated safety beacons in VC systems. LÄS MER

  7. 5. Evaluation and Improvement of Decentralized Congestion Control for Multiplatooning Application

    Master-uppsats, KTH/Radio Systems Laboratory (RS Lab)

    Författare :Chumeng Bai; [2018]
    Nyckelord :Wireless vehicular communication; decentralized congestion control; cooperative awareness messages; multiplatooning; simulation; Trådlös fordonskommunikation; decentraliserad överbelastning kontroll; kooperativ medvetenhet meddelanden; multiplatooning; simulering;

    Sammanfattning : Platooning has the potential to be a breakthrough in increasing road capacity and reducing fuel consumption, as it allows a chain of vehicles to closely follow each other on the road. When the number of vehicles increases, platoons will follow one another in what is referred to as multiplatooning. LÄS MER
