Minimizing Age of Information on NOMA Communication Schemes for Vehicular Communication Applications

Abstract

Real-time communication schemes supporting fresh information are of major importance for vehicular networks. In this direction, the Age of Information (AoI) concept is a power-full tool to operate with. Current publications bring equal importance to the AoI of packets in spite of the common case of unequal channel capacity and source entropy between them, this results in reduced user perception of fairness. This report analyses the use of power-domain NOMA to balance the assigned power between nodes to reduce the overall AoI. We verify an improved user perception of fairness in regard to the freshness of information at the destination.
