PAVAN: a policy framework for content availabilty in vehicular ad-hoc networks

Advances in wireless communication, storage and processing are realizing next-generation in-vehicle entertainment systems. Even if hundreds of different video or audio titles are stored among several vehicles in an area, only a subset of these titles might be available to a given vehicle depending on its current location, intended path, and the dynamics of its ad-hoc network connectivity. The vehicle’s entertainment system must somehow predictively determine which titles are available either immediately or within the future δ time units, so that the user can select a title to view. The available title list must seek to satisfy the user by striking a delicate balance between showing far fewer titles than can actually be accessed and showing too many titles that cannot be accessed. In addition to defining this availability problem, we make two key contributions. First, a two-tier system architecture which leverages the low-rate cellular infrastructure to exchange control messages a...
