MobSampling: V2V Communications for Traffic Density Estimation

The authors propose a fully-distributed approach to the online estimation of vehicle traffic density. Their approach envisions vehicles communicating within a VANET and cooperating to collect density measurements through a uniform sampling of the road sections of interest. The proposed scheme does not require the presence of any network infrastructure, central controller or devices triggered by the passage of vehicles, and it is suitable for both highway and urban environments. Results derived through ns-2 simulations in realistic mobility scenarios show that their solution is very effective, providing accurate, on-line estimates of the traffic density with minimal protocol overhead.
