车辆间通信（IVC）是实现先进智能交通系统（ITS）的重要技术之一。传统的IVC是在狭窄区域中通过毫米波的视线通信的车辆到车辆通信。在这里，我们处理更广泛的区域进行性IVC。在本文中，我们提出了动态集成传输控制（DITRAC）的IVC。DITRAC根据自组织车载通信网络通信环境的波动，对车辆的传输功率和传输间隔进行优化。为了估计相邻通信的波动，本文提出了一种简单有效的方法--仿真结果验证了DITRAC算法在IVC中的有效性。
The inter-vehicle communications (IVC) is one of the most important technologies to realize advanced intelligent transport systems (ITS). Conventional IVC is vehicle-to-vehicle communication through line of sight communication by millimeter wave in a narrow area. Here, we deal with more progressive IVC in a wide area. In this paper, we propose Dynamic Integrated Transmission Control (DITRAC) for IVC. DITRAC optimizes transmission power and transmission interval of vehicles according to the fluctuation of the communications circumstance of the ad-hoc vehicular communications network. In order to estimate the fluctuation of the neighboring communications, we present an effective and simple method, the road-weight with receiving history (WH) method. The simulations are conducted to show the validity of DITRAC for IVC.
