车载自组网由于其在智能交通系统中的潜在作用而引起了学术界和工业界的广泛关注。然而，由于车辆移动和无线通信中的衰落，提供一个可靠的和有效的多跳广播服务的车载自组织网络仍然是一个开放的研究课题。在本文中，我们提出了FUZZBR（FUZZy BRadcast），一个基于模糊逻辑的多跳广播协议，用于车载自组网的信息传播。FUZZBR具有低的消息开销，因为它只使用邻居节点的子集来中继数据消息。在中继节点的选择上。FUZZBR联合考虑多个指标的车辆间的距离，节点的移动性和信号强度，采用模糊逻辑。FUZZBR还使用了一个轻量级的重传机制，当中继失败时，它会重新发送数据包。我们使用计算机模拟来评估FUZZBR的性能。
Vehicular ad hoc networks have been attracting the interest of both academic and industrial communities on account of their potential role in Intelligent Transportation Systems (ITS). However, due to vehicle movement and fading in wireless communications, providing a reliable and efficient multi-hop broadcast service in vehicular ad hoc networks is still an open research topic. In this paper, we propose FUZZBR (FUZZy BRoadcast), a fuzzy logic based multi-hop broadcast protocol for information dissemination in vehicular ad hoc networks. FUZZBR has low message overhead since it uses only a subset of neighbor nodes to relay data messages. In the relay node selection. FUZZBR jointly considers multiple metrics of inter-vehicle distance, node mobility and signal strength by employing the fuzzy logic. FUZZBR also uses a lightweight retransmission mechanism to retransmit a packet when a relay fails. We use computer simulations to evaluate the performance of FUZZBR.
