It is basically an extension to the Content Centric Network (CCN) [12] that gives favorable promises in distributed wireless environments. The latter ones seriously call into question the capability of TCP/IP to support stable end-to-end communications due to lack of centralized control, nodes’ mobility, dynamic topologies, intermittent connectivity, and harsh signal propagation conditions. Relying on name-based forwarding and in-network data caching, the NDN architecture has great potential to solve some of the problems encountered by IP-based protocols in wireless networks. Recently, NDN has been adapted into Vehicular Ad hoc Networks (VANET) and hence, got the name Vehicular NDN (VNDN). Existing works show that NDN brings significant performance improvement for typical content-centric applications and can also fit the mobile environment well. However, directly applying NDN to Vehicular Ad hoc Networks (VANET) is confronted with great challenges such as consumer/provider mobility, Interest/Data forwarding, content caching and so on. Several VNDN designs have been proposed to face these challenges and improve the performance of NDN packet forwarding especially in urban VANET scenarios. In this work, we are going to present four VNDN designs. The first one is dubbed V-NDN [17], it illustrates NDN’s promising potential in providing a unifying architecture that enables networking among all computing devices independent from whether they are connected through wired infrastructure, or ad hoc mode. The second design discussed is Navigo [19], It takes a radically new approach to address the challenges of frequent disconnections and sudden topology changes in a vehicle network. Instead of forwarding packets to a specific moving car, Navigo aims at fetching specific pieces of data from multiple potential carriers of the data. The design provides : (1) a mechanism to bind NDN data names to the producer’s geographic area(s) ; (2) an algorithm to guide Interests towards data producers using a specialized shortest path over the road topology ; and (3) an adaptive discovery and selection mechanism that can identify the best data source across multiple geographic areas, as well as quickly react to changes in the V2X network.
The third design discussed is a prototype implementation of a hierarchical architecture for content distribution in vehicular network[21]. A cluster-based organization of vehicles is considered based on the Named Data Networking (NDN) model where a subset of reference vehicles named barycenters plays the NDN router role. Complementary functionalities of both short-range and cellular communications are used, the former for vehicle-to-vehicle (V2V), the latter for vehicle-to-infrastructure (V2I) communications, to off-load the fixed NDN infrastructure, and increase the chance of finding a content in the VANET, while limiting the number of broadcasted information.iv And for last, the fourth design presented is VEhicular Named Data NETwork (VENDNET)[22] according to three different vehicle communication mechanisms, which are vehicle-toinfrastructure (V2I), a hybrid of vehicle to road side unit (V2R) and vehicle to vehicle (V2V). To evaluate the performance of NDN packet forwarding strategies in urban scenarios, we illustrate the experimental results conducted by ndnSIM of the following strategies : Best-Route ; multicast ; NCC ; and client control | | note de thèses : | Mémoire de master en informatique |
