本发明实施例提供了一种车联网信息传输方法，应用于路边单元RSU，在高速公路安全应用环境中，RSU的执行目标是收集道路交通信息和车辆信息，以实现信息的智能采集和集中处理。由于RSU自身无线通信范围受到限制，因此需要借助移动的车辆共同完成数据采集过程。如图2所示，该方法包括以下步骤：The embodiment of the present invention provides a method for transmitting information of the Internet of Vehicles, which is applied to the roadside unit RSU. In the highway safety application environment, the execution goal of the RSU is to collect road traffic information and vehicle information, so as to realize the intelligent collection and concentration of information deal with. Due to the limited wireless communication range of the RSU itself, it is necessary to complete the data collection process with the help of moving vehicles. As shown in Figure 2, the method includes the following steps:
步骤21：获取车辆状态信息。Step 21: Obtain vehicle status information.
其中，车辆状态信息用于指示车辆的行驶状态，RSU可周期性指示其覆盖范围内的车辆上报各自的车辆状态信息。可选地，本发明实施例中的车辆状态信息包括但不限于以下参数中的至少一项：车辆标识、小区的小区标识、车辆的车速、车辆位置、车辆的信息传输速率、信息传输时延、以及车辆与RSU 之间的信道质量等。其中，车辆标识用于指示车辆的身份信息，如车辆ID。小区的小区标识指示车辆当前所属小区的小区标识，以便于RSU判断车辆是否为自身覆盖小区内的车辆。车辆位置指的是车辆在RSU覆盖小区内的当前位置。车辆的信息传输速率指的是车辆支持或车辆当前的信息传输速率，该参数可能与当前信道质量相关。信息传输时延指的是车辆与RSU进行信息传输的时延，该参数也可能与信道质量相关。车辆与RSU之间的信道质量用于指示车辆与RSU当前的信道质量。Among them, the vehicle status information is used to indicate the driving status of the vehicle, and the RSU can periodically instruct the vehicles within its coverage to report their respective vehicle status information. Optionally, the vehicle status information in this embodiment of the present invention includes, but is not limited to, at least one of the following parameters: a vehicle identifier, a cell identifier of a cell, a vehicle speed, a vehicle location, a vehicle information transmission rate, and an information transmission delay. , and the channel quality between the vehicle and the RSU, etc. Among them, the vehicle identification is used to indicate the identity information of the vehicle, such as the vehicle ID. The cell identifier of the cell indicates the cell identifier of the cell to which the vehicle currently belongs, so that the RSU can determine whether the vehicle is a vehicle in the cell covered by itself. The vehicle location refers to the current location of the vehicle in the cell covered by the RSU. The information transmission rate of the vehicle refers to the vehicle support or the current information transmission rate of the vehicle, and this parameter may be related to the current channel quality. The information transmission delay refers to the delay of information transmission between the vehicle and the RSU, and this parameter may also be related to the channel quality. The channel quality between the vehicle and the RSU is used to indicate the current channel quality between the vehicle and the RSU.
步骤22：根据车辆状态信息，在车队中选择一个车辆作为头节点车辆；其中，车队包括RSU覆盖小区内的全部车辆。Step 22: According to the vehicle state information, select a vehicle in the fleet as the head node vehicle; wherein, the fleet includes all the vehicles in the cell covered by the RSU.
其中，头节点车辆又可称为簇头车辆、簇头节点等。车队包括RSU覆盖小区内的全部车辆，由于车辆的移动性，车队中所包含的车辆也是动态变化的。例如车队当前包括的车辆有：车辆A、车辆B、车辆C，过一段时间之后，车队包括的车辆可能变化为：车辆C和车辆D。因此步骤22也可以是动态过程，例如RSU在车队内车辆发生变化时，根据车辆状态信息在车队中选择头节点车辆。或者，RSU按照特定周期(如间隔预设时间)，根据车辆状态信息在车队中选择头节点车辆。Among them, the head node vehicle may also be called a cluster head vehicle, a cluster head node, and the like. The fleet includes all the vehicles in the cell covered by the RSU. Due to the mobility of the vehicles, the vehicles included in the fleet also change dynamically. For example, the vehicles currently included in the fleet include: vehicle A, vehicle B, and vehicle C. After a period of time, the vehicles included in the fleet may change to vehicle C and vehicle D. Therefore, step 22 can also be a dynamic process. For example, when the vehicles in the fleet change, the RSU selects the head node vehicle in the fleet according to the vehicle state information. Alternatively, the RSU selects the head node vehicle in the fleet according to the vehicle state information according to a specific period (eg, a preset time interval).
可选地，车辆状态信息包括但不限于以下参数中的至少一项：车辆标识、小区的小区标识、车辆的车速、车辆位置、车辆的信息传输速率、信息传输时延、以及车辆与RSU之间的信道质量等。以车辆标识为例，RSU可根据车辆标识确定车辆的终端能力，将终端能力最强的车辆作为头节点车辆。以小区的小区标识为例，RSU将最早或最晚记录的小区标识对应的车辆作为头节点车辆。以车速为例，RSU将车速均匀、车速最接近平均车速、车速最慢或车速最快的车辆作为头节点车辆。以车辆位置为例，RSU将车辆位置指示的距离 RSU最近的车辆作为头节点车辆。以车辆的信息传输速率为例，RSU将信息传输速率最快的车辆作为头节点车辆。以信息传输时延为例，RSU将信息传输时延最低的车辆作为头节点车辆。以车辆与RSU之间的信道质量为例，RSU 将信道质量最优的车辆作为头节点车辆。Optionally, the vehicle status information includes, but is not limited to, at least one of the following parameters: vehicle identification, cell identification of the cell, vehicle speed, vehicle location, vehicle information transmission rate, information transmission delay, and the relationship between the vehicle and the RSU. channel quality, etc. Taking the vehicle identification as an example, the RSU can determine the terminal capability of the vehicle according to the vehicle identification, and use the vehicle with the strongest terminal capability as the head node vehicle. Taking the cell ID of the cell as an example, the RSU takes the vehicle corresponding to the cell ID recorded at the earliest or the latest as the head node vehicle. Taking vehicle speed as an example, RSU takes the vehicle with uniform speed, closest to average speed, slowest or fastest vehicle as head node vehicle. Taking the vehicle position as an example, the RSU takes the vehicle closest to the RSU indicated by the vehicle position as the head node vehicle. Taking the information transmission rate of the vehicle as an example, the RSU takes the vehicle with the fastest information transmission rate as the head node vehicle. Taking the information transmission delay as an example, the RSU takes the vehicle with the lowest information transmission delay as the head node vehicle. Taking the channel quality between the vehicle and the RSU as an example, the RSU takes the vehicle with the best channel quality as the head node vehicle.
步骤23：发送携带有头节点车辆标识信息的指示信息。Step 23: Send the indication information carrying the vehicle identification information of the head node.
RSU在确定头节点车辆后，发送携带有头节点车辆标识信息的指示信息。其中，该指示信息可以是RSU广播给覆盖小区内的所有车辆的，也可以是RSU 专门发送给覆盖小区内的所有车辆的。为了节省网络开销，RSU也可以只发送给头节点车辆，再由头节点车辆广播或转发给队列车辆。队列车辆为车队中除头节点车辆之外的车辆。After determining the head node vehicle, the RSU sends the indication information carrying the head node vehicle identification information. The indication information may be broadcast by the RSU to all vehicles in the coverage cell, or may be specially sent by the RSU to all vehicles in the coverage cell. In order to save the network overhead, the RSU can also be only sent to the head node vehicle, and then broadcast or forwarded to the queue vehicle by the head node vehicle. A platoon vehicle is a vehicle other than the head node vehicle in the platoon.
这样，RSU通过上述方式选择位于其无线传输范围(覆盖小区)之内的车辆作为头节点车辆，使得所有选定的头节点车辆在空间上形成一维簇头链状网络结构可实现拓展RSU信息收集范围的目的。In this way, the RSU selects vehicles located within its wireless transmission range (covered cell) as the head node vehicle through the above method, so that all the selected head node vehicles form a one-dimensional cluster head chain network structure in space, which can realize the expansion of RSU information The purpose of the collection scope.
在本发明的一个实施例中，步骤22可以包括：根据车辆状态信息，确定车辆的效用函数值，其中，效用函数值用于评估车辆的管理车队能力；根据车辆的效用函数值，在车队中选择一个车辆作为头节点车辆。其中，效用函数值是根据车辆状态信息中至少一个参数经过特定函数运算得出的值，其用于评估车辆的管理车队能力。可选地，由于头节点车辆的一个重要功能为：接收与发送网络设备的数据，因此车辆与RSU之间的信道质量会严重地影响二者之间的通信状况。因此，在头节点选择过程中，车辆与RSU之间的信道质量为重要的参考因子。本发明实施例中，以上介绍了根据一维车辆状态信息来选择头节点车辆的方式，下面本实施例将进一步介绍：RSU可以从车辆多维车辆状态信息：车辆标识、所述小区的小区标识、所述小区内车辆的车速、车辆位置、车辆的信息传输速率、信息传输时延、以及车辆与所述RSU之间的信道质量，来建立指示管理车队能力大小的效用函数。In one embodiment of the present invention, step 22 may include: determining a utility function value of the vehicle according to the vehicle state information, wherein the utility function value is used to evaluate the vehicle's ability to manage a fleet; according to the utility function value of the vehicle, in the fleet Select a vehicle as the head node vehicle. The utility function value is a value obtained through a specific function operation according to at least one parameter in the vehicle state information, which is used to evaluate the vehicle fleet management capability. Optionally, since an important function of the head node vehicle is to receive and transmit data of network equipment, the channel quality between the vehicle and the RSU will seriously affect the communication status between the two. Therefore, in the head node selection process, the channel quality between the vehicle and the RSU is an important reference factor. In the embodiment of the present invention, the method of selecting the head node vehicle according to the one-dimensional vehicle state information has been introduced above, and this embodiment will be further introduced below: the RSU can obtain the multi-dimensional vehicle state information of the vehicle from the vehicle identification, the cell identification of the cell, The vehicle speed, vehicle location, vehicle information transmission rate, information transmission delay, and channel quality between the vehicle and the RSU in the cell are used to establish a utility function indicating the ability to manage the fleet.
