Abstract

In this paper, a novel power auctioneers network (PAN) is proposed to enable the sharing of resources from licensed users in exchange for performance gains using the Cooperative Non-Orthogonal Multiple Access (C-NOMA) protocol. This system exploits a matching-based algorithm based on game theory, namely Pragmatic Distributed Algorithm (PDA), to handle the challenge of user pairing and power allocation in C-NOMA. PDA is a cooperative game that allows for the sharing of potential relays within a network through a round-robin approach, allowing for fairer resource distribution. This approach uses distributed methods to perform tasks on user devices to remove the strain on the base station's resources. Monte Carlo simulations demonstrate that the addition of these games to a wireless network provides a significant performance increase compared to traditional orthogonal multiple access methods, the unoptimised C-NOMA and the Distributed Matching Algorithm (DMA) method. Lastly, the idea of instability in matching algorithms in the context of wireless communications is explored by altering the number of users within a network.
