Abstract
This paper aims to propose a new solution for failure recovery (dead-ends) in Vehicle to Vehicle (V2V) communications through LTE-assisted Device-to-Device communications (D2D). Based on the enhanced networking capabilities offered by Intelligent Transportation Systems (ITS) architecture, our solution can efficiently assist V2V communications in failure recovery situations. We also derive an analytical model to evaluate generic V2V routing recovery failures. Moreover, the proposed hybrid model is simulated and compared to the generic model under different constrains of worst and best cases of D2D discovery and communication. According to our comparison and simulation results, the hybrid model decreases the delay for alarm message propagation to the destination (typically the Traffic Control Center TCC) through the Road Side Unit (RSU).
本文旨在通过lte辅助的设备对设备通信(D2D),为车对车(V2V)通信中的故障恢复(死角)提出一种新的解决方案。基于智能交通系统(ITS)架构提供的增强网络功能,我们的解决方案可以在故障恢复情况下有效地协助V2V通信。我们还推导了一个分析模型来评估通用的V2V路由恢复故障。在D2D发现和通信的最坏和最佳情况的不同约束条件下,对所提出的混合模型进行了仿真,并与通用模型进行了比较。对比和仿真结果表明,混合模型减少了报警信息通过路侧单元(Road Side Unit, RSU)传播到目的地(通常是交通控制中心TCC)的延迟。
