An Enhanced Power Control Transmission Scheme Based on CVIA

This paper designs a new scheme based on Controlled Vehicular Internet Access (CVIA), a protocol that divides a straight road into several segments. To avoid hidden nodes and reduce unnecessary CTS/RTS, vehicles send the packet to the RSU segment by segment. The features of CVIA include its high end-to-end throughput and fairness between road segments. However, a significant problem of CVIA is that the transmission will terminate when there is no vehicle in the segment, which is also called the hole problem. To solve this problem, a novel power control transmission scheme is proposed in this paper. The simulation results show that our proposed scheme exactly solves the hole problem.
