Named Data Networking (NDN) has been proposed as a future Internet architecture that naturally supports multi-path data delivery and allows for widespread in-network caching to address this challenge. With the provision of network caching, NDN transforms the traditional host-centric TCP/IP architecture into a content-centric one by substituting content names for IP addresses. Several studies have investigated NDN deployment in VANETs given birth to a new paradigm called Vehicular Named Data Networking (VNDN). As part of the evolution of VANETs, Vehicular Social Networks (VSNs), which emerge as the combination between social networks and Vehicular Ad-Hoc Networks (VANETs), face several challenges in content dissemination and caching within VSNs due to the transient nature of links and intermittent connectivity resulting from high vehicle mobility.
In the challenging VSN environment, VNDN proves to be a favorable communication paradigm, as it effectively optimizes content dissemination by dissociating content from its physical location. Nonetheless, content dissemination and caching pose significant challenges in VSNs due to the transient nature of links and intermittent connectivity resulting from high vehicle mobility. We aim through our contribution to enhance content delivery, cache hit ratio, and reduce transmission delays for end-users. To achieve this, we propose a novel hybrid VNDN-VSN forwarding technique based on social communities, enabling requester vehicles to efficiently locate suitable forwarders or producers among community members in their vicinity. Additionally, we introduce an efficient caching mechanism by partitioning the content store into community-private and public sections.
Simulation results demonstrate that our proposed forwarding technique outperforms traditional VNDN in terms of data delivery ratio, average delivery delay, and cache hit ratio. | | note de thèses : | Thése de doctorat en informatique |
