在本文中，我们提出了一种车间信息传播协议，称为接收消息相关协议（RMDP），传播前面的交通信息，以下车辆，并讨论其性能。拟议的协议根据接收消息的数量和检测到的接收错误自主改变传播间隔，以避免车辆之间的消息冲突。我们已经构建了一个逼真的仿真环境，通过结合交通流模拟器和ad hoc网络模拟器的车辆间通信。我们的仿真结果表明，通过使用RMDP，许多车辆可以在短时间内获得他们的前面的交通信息，在轻，重交通条件。此外，我们还表明，传播数据的选择政策影响先行交通信息的获取时间。每辆车都会在一段时间内保留其他车的痕迹。根据所保存的其他车辆的轨迹的数量和它们的保存时间段，先前交通信息的传播比率变化。一些模拟结果进行了解释。
In this paper, we propose an intervehicle information dissemination protocol called received message-dependent protocol (RMDP) that propagates the preceding traffic information to the following vehicles and discuss its performance. The proposed protocol autonomously changes the dissemination interval, depending on the number of reception messages and detected reception errors, in order to avoid message collision among vehicles. We have constructed a realistic simulation environment of intervehicle communication by combining a traffic-flow simulator and an ad hoc network simulator. Our simulation results show that, by using RMDP, a lot of vehicles can acquire their preceding traffic information within short periods at both the conditions with light and heavy traffic. In addition, we have also shown that selection policy of disseminated data affects preceding-traffic-information acquisition time. Each vehicle holds other vehicles' traces for some period. Depending on the number of preserved other vehicles' traces and their preserved periods, the propagation ratio of the preceding traffic information varies. Some simulation results are explained.
