项目摘要

Vehicular ad hoc networks (VANETs) have been attracting interest in recent years for their potential uses in intelligent transport systems. In this research, we proposed a reliable and efficient multi-hop broadcast protocol which can be used to deliver emergency messages in VANETs. The proposed protocol selects relay nodes by employing a fuzzy logic to jointly consider inter-vehicle distance, vehicle movement and received signal strength. The protocol also uses an efficient retransmission mechanism to recover from packet losses. The proposed protocol was evaluated by using a real world vehicular ad hoc network. The experimental results showed that the proposed protocol can provide a high packet dissemination ratio, low message overhead and low end-to-end delay.

车载自组织网络（VANESTs）近年来因其在智能交通系统中的潜在应用而引起人们的兴趣。在本研究中，我们提出了一个可靠且有效的多跳广播协定，可用于在VAN中传送紧急讯息。建议的协议选择中继节点采用模糊逻辑，共同考虑车辆间的距离，车辆运动和接收信号强度。该协议还使用了一个有效的重传机制来恢复数据包丢失。通过使用一个真实的世界车载ad hoc网络所提出的协议进行评估。实验结果表明，该协议具有较高的分组分发率、较低的消息开销和较低的端到端延迟。
