LTE-D2D for connected cars: a survey on radio resource management schemes

Abstract

Long-Term Evolution (LTE) is a promising technology to be applied for different applications due to its high penetration, high data rate, reliability, and QoS support. One of the emerging applications for LTE is vehicular networks. Vehicular networks can raise traffic safety, improve traffic management, or provide infotainment services for road users. LTE device-to-device (LTE-D2D) communication which was proposed by 3GPP working group is also a good candidate to be applied for vehicleto-vehicle communications (V2V). The V2V communication for traffic safety has strict QoS requirements in terms of latency and reliability. LTE-D2D may provide high reliability and low latency for such a communication. However, an efficient radio resource management for V2V communications in an LTE network is required to support such requirements. In the current article, we introduce vehicular networks, their requirements, and existing technologies to be employed in them and specially look at LTE-D2D to connect cars. Most recent works in radio resource management for V2V communications in LTE are reviewed in this work.

Multiobjective optimization‐based radio resource allocation and sharing algorithm for D2D‐based V2V communication

“…Moreover, the lack of strict quality of service (QoS) provisioning and the central management in the 802.11p technology challenges the satisfaction of vehicle‐to‐vehicle (V2V) users' requirements . Device‐to‐device (D2D) communications based on Long Term Evolution (LTE) networks can be considered as one of the best solutions to resolve the problem where devices collaborate and communicate with each other in an autonomous way, without centralized control. D2D communications can maximize the reliability and decrease the delay.…”
