Stable Fixture Model Implementation in LTE V2X Communications

Abstract

The study item: “Feasibility Study on LTE-based V2X Services”, approved at 3GPP TSG RAN #68, has drawn much attention in the study of the LTE assisted V2V and V2I communications in the vehicular networks. By deploying the D2D technology adopted in the traditional cellular networks into the V2X communications (including both the V2V and V2I communications), performance improvements can be expected, such as better reliability, lower latency, and more efficient content sharing. This chapter investigates the content sharing problem in the D2D-based V2X communications. With both vehicles and eNBs carrying different types of data, this chapter studies how to optimize the information exchanged within the network. By jointly considering the data diversity and the communication link quality, the interactions between the vehicles/eNBs are modeled as the SF matching game. Different from the traditional D2D communications, we allow vehicles.eNBs to set up multiple link connections for to further optimize the content sharing in the Vehicular ad hoc networks (VANETs). The SF game is solved by the Irving’s stable fixture (ISF) algorithm.
