Background. Due to the great increase of accident into roads, vehicular communication becomes the focus of many researchers. Therefore vehicular communication is becoming an active topic of search. That’s why safety driving is the main concern of many researcher to mitigate congestion problems specifically following urban scenario. Due to the requirement of URLLC, we investigate in this paper the importance of power diminishing. In fact, power minimization is an interesting metric due to the requirement of high data rates.
Objective. The aim of the paper is to investigate power allocation into LTE-V system following a decentralized scenario.
Methods. The idea is to consider a platoon with a set of vehicles interacting together for network resources without the help of ENodeB. Power consumption minimization is a promising solution for interference diminishing since vehicles
communicate according to a decentralized way. In this regard the theoretical analysis is based on applying stackelberg game policy for power control in the way to minimize interference.
Results. We conclude that stackelberg game policy is a powerful tool for interference and power consumption management. Computer results highlight the efficiency of SK game for power allocation into a decentralized scenario.
Conclusions. Vehicular Autonomous communication attracted the attention of many researchers according to increasing number of congestion together with traffic problems. In addition, to ensure better safety we adopt platooning scenario which enables mitigations of many problems such as collisions, congestion. Inter-car communication is an interesting topic of search
to ensure safety into-roads. In addition, platooning has the potential to ensure safety with low energy consumption specifically towards urban traffic. In addition, LTE-V is a heuristic solution for vehicular communication where the connectivity is performed in a decentralized context without the requirement of the ENodeB.
