The efficient usage of multiple channels allocated for vehicular communications is deemed crucial to support the increasing spectrum demand of current and upcoming Intelligent Transportation Systems (ITS). In this context, an accurate modeling of adjacent channel interference (ACI) is needed to better understand its adverse effects on simultaneous communications on different channels. In this paper,...
Driving vehicles in platoons has the potential to improve traffic efficiency, increase safety, reduce fuel consumption, and make driving experience more enjoyable. A lot of effort is being spent in the development of technologies, like radars, enabling automated cruise control following and ensuring emergency braking if the driver does not react in time; but these technologies alone do not empower...
Given the broad acceptance of the DSRC/WAVE protocol stack in the vehicular networking community, both the automotive industry and the scientific community are working towards so-called “day one” applications. Currently, large scale field operational tests are going on to assess the performance of developed protocols and applications. Still, the key technique for performance evaluation is simulation...
We discuss the applicability of simplified Two-Ray Ground path loss models to simulation-based performance evaluation studies of Inter-Vehicle Communication (IVC) protocols. We contrast this with the applicability of a more exact Two-Ray Interference model. A key result is that, in most cases, the commonly used simplified Two-Ray Ground models add no additional value compared to the most simple Free-space...
