Center node: "realtime estimation of ieee 802 11p for mobile working machines communication respecting delay and packet loss"
  Abstract: The fleet management of mobile working machines with the help of connectivity can increase not only safety but also productivity. However, rare mobile working machines have taken advantage of V2X. Moreover, no one published the simulation results that are suitable for evaluating the performance of the ad-hoc network at a working site on the highway where is congested, with low mobility, and without building. In this paper, we suggested that IEEE 802.11p should be implemented for fleet management, at least for the first version. Furthermore, we proposed an analytical model for machines to estimate the ad-hoc network performance about the expected delay and the probability of packet loss in real-time based on the simulation results we made in ns3. The model of this paper can be used for determining when shall ad-hoc or cellular network be used in the corresponding scenario.
