Abstract EN
Vehicle-to-vehicle communication plays a significantly important role in implementing safe and efficient road traffic.
When disseminating safety messages in the network, the information quantity on safety packets changes over time and space.
However, most of existing protocols view each packet the same to disseminate, preventing vehicles from collecting more recent and precise safety information.
Hence, an information quantity-based broadcast protocol is proposed in this paper to ensure the efficiency of safety messages dissemination.
In particular, we propose the concept of emergency-degree to evaluate packets’ information quantity.
Then we present EDCast, an emergency-degree-based broadcast protocol.
EDCast differentiates each packet’s priority for accessing the channel based on its emergency-degree so as to provide vehicles with more safety information timely and accurately.
In addition, an adaptive scheme is presented to ensure fast dissemination of messages in different network condition.
We compare the performance of EDCast with those of three other representative protocols in a typical highway scenario.
Simulation results indicate that EDCast achieves higher broadcast efficiency and less redundancy with less delivery delay.
What we found demonstrates that it is feasible and necessary for incorporating information quantity of messages in designing an efficient safety message broadcast protocol.
