Most applications in urban Vehicular Ad hoc NETworks (VANETs) rely on information sharing, such as real-time traffic information queries, advertisements, etc. However, existing data dissemination techniques cannot guarantee satisfactory performance when a lot of information requests come from all around the network. Because these pieces of information are useful for multiple users located in various...
Named Data Networking (NDN) is a data-centric architecture designed for the future Internet. 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 (VANETs) is confronted with great challenges due to the high mobility of vehicles. Most...
Data dissemination is an important technology for most VANET applications. Due to the physical factors like traffic lights, the density of vehicles is usually uneven. Areas near intersections often have a high node density while areas near the center of streets can have a very low node density. The uneven distribution of nodes and the movement pattern of vehicles cause intermittent connections and...
Geographical source routing is a promising routing technique for VANETs, due to its adaptability for network dynamics and ability to handle topology holes. In traditional geographical source routing algorithms a best-known neighbor, typically the neighbor closest to the next junction in a greedy fashion, is designated as the next hop. This approach may cause two drawbacks: (1) the designated neighbor...
