Public ISBD Titre : RAND-WHISPER : a randomized transmission power scheme for enhanced location privacy in the internet of vehicles Type de document : document multimédia Auteurs : Taieb Derrah, Auteur ; Messaoud Babaghayou, Directeur de thèse Editeur : Laghouat : Université Amar Telidji - Département d'informatique Année de publication : 2026 Importance : 75 p. Accompagnement : 1 disque optique numérique (CD-ROM) Note générale : Option : Networks, systems and distributed applications Langues : Anglais (eng) Mots-clés : Internet of vehicles  Location privacy  Transmission power control  Randomization  RAND-WHISPER  VANET  OMNeT++, Veins  SUMO  PREXT Résumé : With the rapid growth of the Internet of Vehicles (IoV), vehicles continuously broadcast beacon messages containing sensitive information such as location, speed, and trajectory, exposing them to serious privacy threats including tracking and correlation attacks. Although existing mechanisms such as pseudonym changes, silent periods, and mix zones provide partial protection, they remain vulnerable to pattern-based tracking due to deterministic transmission behavior. This thesis proposes RAND-WHISPER, a randomized transmission power scheme designed to enhance location privacy in IoV environments. Built upon the WHISPER (WSP) scheme, RAND-WHISPER introduces controlled randomness into the transmission power selection by applying a ±ε variation around speed-based power levels, reducing communication pattern predictability and making it significantly harder for adversaries to track vehicles over time. The scheme is implemented and evaluated using OMNeT++, Veins 4.4, and SUMO within the PREXT framework, using a real road network of Tlemcen city, under vehicle densities ranging from 50 to 250. Results demonstrate that RAND-WHISPER achieves improved location privacy compared to WSP and other baselines, while maintaining acceptable communication performance. note de thèses : Mémoire de master en informatique RAND-WHISPER : a randomized transmission power scheme for enhanced location privacy in the internet of vehicles [document multimédia] / Taieb Derrah, Auteur ; Messaoud Babaghayou, Directeur de thèse . - Laghouat : Université Amar Telidji - Département d'informatique, 2026 . - 75 p. + 1 disque optique numérique (CD-ROM).
