In this paper, we study the performance of energy-efficient resource allocation schemes for multi-cell OFDMA networks based on Game Theory. These schemes have been evaluated in the literature; however, the evaluations have been done under different system models and simulation environments, making a fair comparison unfeasible. Hence, we first develop an appropriate system model for comparison. Then, we analyze the implementation of the selected schemes under constraints introduced by the proposed system model. Finally, throughout extensive numerical simulations on a realistic environment, we evaluate the performance and tradeoffs between energy efficiency, throughput, outage probability and fairness, highlighting the need for some scheme that improves the outage probability and the throughput maintaining high energy efficiency.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
