Public ISBD Titre : Adaptive routing protocols for high-throughput and Long-LifeTime data transmission in IoUT Type de document : document multimédia Auteurs : Nadjia Azzouz, Auteur ; Soulaf Nour Elyakine Ben Messaoud, Auteur ; Abdelmadjid Ben Arfa, Directeur de thèse Editeur : Laghouat : Université Amar Telidji - Département d'informatique Année de publication : 2026 Importance : 69 p. Accompagnement : 1 disque optique numérique (CD-ROM) Note générale : Option : Distributed networks, systems and applications Langues : Anglais (eng) Mots-clés : Internet of underwater things  Adaptive routing  Vector-based forwarding  Energy efficiency  Network Lifetime  NS-3  AquaSim Résumé : This thesis addresses the critical challenge of routing in the Internet of Underwater Things (IoUT), where extreme node mobility and severe energy constraints threaten network performance. Existing location-based protocols, notably Vector-Based Forwarding (VBF), suffer from communication voids and energy hot-spots due to static geometric thresholds that are incompatible with dynamic underwater topologies. We propose Adaptive-IOUT-VBF, a novel density-aware routing protocol featuring: (1) a dynamic pipe radius mechanism that expands in sparse regions to prevent void formation and contracts in dense regions to suppress redundant transmissions; and (2) an implicit geometric preference mechanism based on holding-time competition, where relay priority is determined by pipe-axis proximity while load distribution is ensured through the energy-aware adaptive radius formulation. The protocol operates in a fully localized, stateless manner, ensuring scalability without global topology maintenance. Implemented in NS-3/AquaSim, Adaptive-IOUT-VBF is rigorously evaluated against Classic-VBF, HHVBF, and DBR across six scenarios spanning node density, mobility, field area, pipe radius, traffic load, and water depth. Results demonstrate superior throughput scalability at high densities, maximized network lifetime through balanced energy distribution, and consistently the lowest energy gap among all protocols. The trade-off of marginally increased hop count is structurally justified by the load-balancing strategy. This work establishes a robust foundation for long-duration, unattended underwater sensor deployments. note de thèses : Mémoire de master en informatique Adaptive routing protocols for high-throughput and Long-LifeTime data transmission in IoUT [document multimédia] / Nadjia Azzouz, Auteur ; Soulaf Nour Elyakine Ben Messaoud, Auteur ; Abdelmadjid Ben Arfa, Directeur de thèse . - Laghouat : Université Amar Telidji - Département d'informatique, 2026 . - 69 p. + 1 disque optique numérique (CD-ROM).
