We propose in this paper a Hybrid Software‐Defined Networking‐based Geographical Routing Protocol (HSDN‐GRA) with a clustering approach. It takes into account three different criteria to select the best relay to send data: (1) the contact duration between vehicles, (2) the available load of each vehicle, (3) and the log of encountered communication errors embedded in each cluster head. The multi‐criteria strategy allows the selection of the most reliable vehicles by avoiding communication problems and ensuring connection availability. Once the hybrid control plane has found out the next eligible neighbor, the data plane will be in charge of dividing and sending data. To validate our approach, HSDN‐GRA has been modeled and implemented in JADE, a multi‐agent platform, to be compared to other multi‐agent based protocols. Simulation results show that HSDN‐GRA achieves good performance with respect to the average routing overhead, the packet drop rate, and the throughput.

HSDN‐GRA：混合软件定义的基于网络的地理路由协议，采用多代理方法

我们在本文中提出了一种采用聚类方法的基于混合软件定义网络的地理路由协议（HSDN‐GRA）。它考虑了三个不同的标准，以选择最佳的中继来发送数据：（1）车辆之间的接触持续时间；（2）每个车辆的可用负载；（3）以及每个群集头中嵌入的通信错误日志。多标准策略可以避免通讯问题并确保连接可用性，从而选择最可靠的车辆。一旦混合控制平面找到了下一个合格邻居，数据平面将负责划分和发送数据。为了验证我们的方法，已在多代理平台JADE中对HSDN‐GRA进行了建模和实施，以与其他基于多代理的协议进行比较。
