Avoiding the Gridlock

In this book, we analyze information dissemination in
the context of vehicle-to-vehicle communication in
vehicular ad hoc networks (VANETs). In order to
inform cars about current traffic situations in a
city scenario, information needs to be spread in the
whole network. By analyzing the interaction between
high node mobility, road topology and radio
characteristics of this network we identify the two
major challenges of information dissemination in
VANETs: i) limited connectivity and ii) limited
bandwidth. We tackle the first challenge by
positioning additional infrastructure-based
supporting units. In oder to approach the second
challenge, we propose different aggregation
mechanisms. These aim to minimize the amount of data
transmitted in the network. It allows thus to inform
all vehicles in the network in due time about current
road situations. This book addresses readers
interested in mobile ad hoc networks, in particular
researchers and developers working on vehicular networks.
