Auction-Based Information Freshness in 5G Power Communications Relay Networks

With the development of novel power systems, emerging scenarios such as real-time power trading, and real-time control of virtual power plants demand higher standards for the timeliness of power information. We consider a two-way relay network that consists of two users and one relay. Two users are the information sources and destinations of each other, which is cooperative communication. Two users can not connect directly, users finish the transmission through the relay. We propose the auction-based information freshness in two-way relay network. The relay is the auctioneer and users are bidders. We build up Cooperative Game to solve information freshness and prove that there is a unique Nash Equilibrium in relay network. Simulation results validate our theoretical analysis and the impact of information freshness in the system.
