Abstract:
In vehicle-to-infrastructure (V2I) communications, the challenge regarding how to achieve the intended performance at the minimal resource cost has yet been well addressed in the recent development of vehicular technologies. In this paper, we investigate some data transmission schemes, such as cooperative communications, for improving quality of service (QoS) in vehicular networks. We propose a method that facilitates V2I through vehicle-to-vehicle (V2V) communications and, for this approach, we derive the closed-form expressions of the outage probability, throughput, energy efficiency and packet loss rate for four different transmission schemes investigated. The QoS performances can be optimized by finding appropriate transmission schemes with a certain number of relays within a given transmission distance. The proposed approach is also aimed to achieve the best performance trade-off between system reliability and efficiency under various environmental conditions.
