Many multi-hop broadcast protocols have been proposed in Vehicular Ad Hoc Networks (VANETs) in order to alleviate the broadcast storm problem. In urban environments, it is important to consider the highly dynamic network topology and the effect of shadowing caused by buildings. Some traditional protocols solve these problems in the way that vehicles near intersections forward packets. However, these...
Geographic routing protocols have been developed for efficient V2V and V2I communications in vehicular ad hoc networks (VANETs). Existing approaches tackle challenges in urban environments such as dynamic vehicular network topology. However, in more realistic urban environments, vehicular networks are highly dynamic due to the complicated road topology and vehicular mobility, as well as shadowing...
The broadcast-based geocast enables efficient data dissemination to vehicles within a given geographical region. When dealing with broadcast, unnecessary retransmissions must be suppressed by controlling the packet forwarding to avoid the broadcast storm problem. However, most of existing broadcast suppression methods do not work in urban environments since buildings block the communication between...
