Abstract

From the decades ago, the ITS (Intelligent Traffic System) became one of the major research field. In order to save human lives, ITS safety applications collect various information from neighboring vehicles. For the ITS safety application, each vehicle periodically broadcasts beacon messages in order to update the information to the neighbors. However, due to the wireless nature of the ITS network, congestion declines performance of the safety application. Previous beacon transmission rate control schemes only focusing on the distributed beacon rate control which each individual node controls its beacon transmission with locally collected channel condition via one-hop neighbors. However, channel condition detected among adjacent node can vary and adapted beacon transmission rate can be various either. This unfairness of number of beacon transmission will decrease awareness on the node which is less frequently transmitting beacon. In this paper, we proposed a request based beacon rate control scheme to alleviate the unfairness of beacon transmission rate while maximizing performance of vehicular safety applications.

基于请求的车载自组织网络自适应信标速率控制方案

从几十年前开始，智能交通系统(ITS)就成为主要的研究领域之一。为了拯救人类的生命，智能交通系统的安全应用程序从附近的车辆收集各种信息。对于ITS安全应用，每辆车定期广播信标信息，以便向邻居更新信息。然而，由于ITS网络的无线特性，拥塞降低了安全应用的性能。以往的信标传输速率控制方案只关注分布式信标速率控制，每个节点通过一跳邻居通过本地采集的信道条件控制信标传输。然而，相邻节点之间检测到的信道条件可能不同，自适应信标传输速率也可能不同。这种信标发送次数的不公平性会降低信标发送频率较低的节点的感知能力。本文提出了一种基于请求的信标速率控制方案，以缓解信标传输速率的不公平性，同时最大限度地提高车辆安全应用的性能。
