Research Area:  Vehicular Ad Hoc Networks
The Internet of Vehicles (IoVs) is an emerging paradigm aiming to introduce a plethora ofinnovative applications and services that impose a certain quality of service (QoS) requirements. The IoVmainly relies on vehicular ad-hoc networks (VANETs) for autonomous inter-vehicle communication androad-traffic safety management. With the ever-increasing demand to design new and emerging applicationsfor VANETs, one challenge that continues to stand out is the provision of acceptable QoS requirements toparticular user applications. Most existing solutions to this challenge rely on a single layer of the protocolstack. This paper presents a cross-layer decision-based routing protocol that necessitates choosing the bestmulti-hop path for packet delivery to meet acceptable QoS requirements. The proposed protocol acquiresthe information about the channel rate from the physical layer and incorporates this information in decisionmaking, while directing traffic at the network layer level. Key performance metrics for the system designare analyzed using extensive experimental simulation scenarios. In addition, three data rate variant solutionsare proposed to cater for various application-specific requirements in highways and urban environments
