Abstract: In this paper, we propose inter-vehicle ad-hoc communication protocols called Speed-Dependent Random Protocol (SDRP), Received-Message-Dependent Protocol (RMDP) and RMDP with Error Counting (RMDPwEC), which disseminate and propagate the preceding traffic information to the following vehicles, and discuss its performance. These protocols dynamically change the dissemination interval depending on the vehicles' speed and the number of reception messages, respectively. Our simulation results show that by using RMDPwEC, a lot of vehicles can acquire the preceding traffic information within very short periods. In addition, we have also shown that selection of disseminated data affects preceding traffic information acquiring time. Each vehicle holds other vehicles' tracks for some period. Depending on the number of preserved other vehicles' tracks and their preserved period, propagation ratio of the preceding traffic information varies. Some simulation results are explained.
