Efficient Inter-Vehicle Data Dissemination
Data services for in-vehicle consumption are expected to become a primary driver in the development of future vehicular networks. Due to download rate limitations of present wide-area cellular connectivity such as 3G (the likely "Pipe" to/from vehicles), and direct peer-to-peer data sharing among vehicles can supplement vertical downloading. This paper studies the inter-vehicle data dissemination problem in a WAVE/802.11p vehicular ad hoc network, using Network Coding (NC). The gains from such NC, relative to a baseline scheme of random transmission, are estimated using analysis and simulations.
