摘要

提出了一种车载 Ad Hoc 网络中基于线性协作策略的交通事故预警信息检测算法，由两个部分组成：局部检测和全局检测。簇首得到移动车辆节点局部检测后的信号强度统计量，进行全局线性组合，做出最终的判决。数值仿真结果表明所提出的策略能在误警概率要求范围内有效提高检测概率，并且避免广播风暴的发生。

Abstract

An alarm message detection algorithm for the traffic accident based on linear cooperative strategy in vehicular Ad Hoc network was proposed

and it was composed of two parts: local detection and global detection. Cluster heads received the statistics of detection signal strength from local mobile vehicle node

and conducted global linear combination to make a final decision. The numerical simulation results show that the proposed strategy can improve the detection probability within the scope of the false alarm probability

and avoid the broadcast storm.
