In this paper, we study the effect of dense vehicular networks on data dissemination. When using intelligent broadcasting techniques, such as Inter-Vehicle Geocast, we have discovered the spatial broadcast storm problem in which multiple vehicles will be chosen to re-broadcast frames at nearly the same time, resulting in channel contention and collisions. We present a probabilistic version of IVG...
We present a method for accurate aggregation of highway traffic information in vehicular ad hoc networks (VANETs). Highway congestion notification applications need to disseminate information about traffic conditions to distant vehicles. In dense traffic, aggregation is needed to allow a single frame to carry information about a large number of vehicles. Our technique, CASCADE, uses compression to...
We present an analysis of the CASCADE (cluster-based accurate syntactic compression of aggregated data in VANETs) data aggregation technique. CASCADE organizes known vehicles into clusters, the size of which determines both the frame size used to distribute aggregated data and the distance ahead that vehicles are aware of (local view). In this paper, we determine the optimal cluster size to balance...
