摘要

本文研究了在新分配的5.9 GHz专用短程通信(DSRC)频谱下公路车辆间的无线通信。为满足公路安全应用的通信需求，设计了一种基于车-车位置广播(LBB)通信协议。在通常满足的假设条件下，导出了协议性能在传输失败概率和信道占用率方面的解析表达式。由表达式得到了性能与设计参数之间的最优关系。测试了协议性能在各种通信条件和公路交通条件下的敏感性。在一定的协议性能要求下，找到通信参数和公路交通参数的可行组合。

Design and analysis of highway safety communication protocol in 5.9 GHz dedicated short range communication spectrum

We study the wireless communication among highway vehicles in the newly-assigned 5.9 GHz dedicated short range communication (DSRC) spectrum. A vehicle-vehicle location-based broadcast (LBB) communication protocol is designed to meet highway safety applications' communication requirements. The analytical expressions of the performance of the protocol in terms of probability of transmission failure and channel occupancy are derived with commonly satisfied assumptions. The optimal relation between the performance and design parameters is obtained from the expressions. The sensitivity of the protocol performance is tested for various communication conditions as well as highway traffic conditions. Feasible combinations of the communication and highway traffic parameters are found for certain requirements on protocol performance.
