In multi-hop dissemination, timer-based and probabilistic methods are high performing methods in Vehicular Ad-hoc Networks (VANETs), owing to their simplicity, low overhead and high efficiency. However, such approaches neglect the fact that vehicle transmission ranges are typically heterogeneous, which could be due to dynamic adjustment of the transmission power value. In our previous work, we introduced...
Information Hovering is a relatively new concept of information dissemination over a mobile set of peers. It naturally applies in many applications in vehicular ad-hoc networks, where useful information needs to be made available to all vehicles within a confined geographical area for a specific time interval. A straightforward approach, is to have all vehicles within the hovering area exchange messages...
Mechanisms for information dissemination are essential for many applications in vehicular ad-hoc networks (VANETs). Currently, simple flooding is often supposed to broadcast information within a geographic region, as for example in many geocast protocols. However, simple flooding has several drawbacks: every node rebroadcasting a message leads to redundancy, contention, and collision, to which is...
