Performance analysis and simulation of vehicle-beacon communications protocols

Due to relatively short communication zones, the data link protocols being developed or proposed for vehicle-beacon communications must be carefully evaluated by analysis and simulation, taking antenna configurations, geometry, propagation, and channel characteristics into account. Different methods for media access control and recovering algorithms after message collision are presented and evaluated. Based on the results from analysis and simulation the optimal system parameters and dimensions can be determined. In addition, it is possible to estimate whether not only a single application (e.g., automatic debiting) but several other RTI applications (e.g., route guidance, parking management, etc.) can be supported by a multiservice beacon.<
