摘　　要：车载雷达通信一体化技术能够高效利用频谱,降低硬件成本,适用于构建智能交通系统自组织网络。面向安装了车载雷达通信一体化系统的智能驾驶车队,设计了一种媒体接入控制协议用于组网。首先为雷达通信一体化系统建立了时隙使用模型。各节点利用雷达扫描的一跳邻居数量信息,估计网内处于通信状态的节点数,利用散列算法选择通信时隙。该协议易于实现,在发送任务增多时,相对于时隙随机接入能够有效降低冲突,获得较高网络吞吐量。Vehicle borne radar communication integration technology can efficiently take ad- vantage of the spectrum to reduce the cost of hardware, which is suitable for the construction of intelligent transportation system. In this paper, a kind of media access control protocol for net- ting was designed, which is an intelligent driving vehicle for vehicle radar communication inte- grated system. A slot model was established for the radar communication integration system. Firstly, each node can use the information of one hop neighbor number to estimate the total num- ber of nodes in the network. Then the communication slot can be selected by using hash algo- rithm. The protocol is easy to implement, and the simulation results show that as transmitting task increases, the proposed protocol can effectively reduce the conflict and obtain higher network throughput.
