摘要

Vehicular Ad Hoc Network (VANET) plays a crucial role in enabling important safety applications such as emergency messages dissemination for alleviating traffic accidents and congestion in urban transportation system. Warning information dissemination is of increasing significance in urban highways due to their special topology structure. Hovering Information is a new paradigm for sharing location-aware warning information. It utilizes the vehicles to relay the messages to other vehicles in an anchor area, e.g. the highway entrances. However, one of the challenges lies on how to keep the messages alive at the expense of light network load. In this article, we propose a Hovering-Based Information Dissemination (HBID) approach. In this scheme, a vehicle adjusts the broadcast interval according to the positions and speeds of all neighboring vehicles and then choose the next relay vehicle. Through this, we can reduce the network load and keep the messages in the anchor area. Numerical simulation results demonstrate the effectiveness of the proposed method.
