Junction-Centric Data Forwarding in Urban Vehicular Communication: Future Direction and Challenges

Abstract

All Data packet transmission is a concept in vehicular communication for achieving road safety based on Intelligent Transportation System (ITS). The packet forwarding is carried out in two scenarios including road zone and junction zone forwarding in order to address the problem of intermittent disconnection that leads to packet loss and packet error. Several studies have been conducted considering these scenarios to achieve effective communication. These studies have been revisited to provide comprehensive understanding in order to further explore the existing solutions. However, the re-visitations of these studies have not considered some of the existing junction zone packet forwarding, which is based on video data transmission. To this end, this paper suggests a qualitative review on Junction-centric Data Packet Forwarding (JDPF) focusing on vehicular communication. Precisely, a review of various junction-centric approaches with their comparative assessment is presented. Major challenges in the junction-centric data packet forwarding are identified as future directions of research. The major issues include high traffic load, incorrect metric priority selection and link disconnection at the junction area. The review would be useful to practitioners and researchers, in terms of augmenting clarity in the junction-centric data packet forwarding literature.
