Using MIMO and cross layer design for VANETs: A review

Vehicular Ad-hoc Networks (VANETs) is a wireless networking technology that can be used to support the emergence of Intelligent Transportation Systems (ITS). The deployment of these systems will allow connected vehicle to communicate each other and also with the road side infrastructures in order to avoid possible accidents and provide more comfort applications to the driver and passenger. The designers of applications in VANETs must consider its characteristics such as the high mobility of the vehicles, rapid change of topology and predicted paths. In addition, they must also consider several factors such as different quality of service (QoS) requirement for different type of applications and reliable transmission link quality. Two potential solutions that can be used to support the large and diverse applications in VANETs are Multiple-Input Multiple-Output (MIMO) processing techniques and cross-layer design among the original layers. This paper will review the benefit of employing those two technologies to improve the overall network performances in VANETs.
