Reliable Energy‐Efficient Uplink Transmission Power Control Scheme in NAN
Feng Ye, Yi Qian, Rose Qingyang Hu · 2018
This chapter focuses on the uplink transmission, because the downlink transmission contains only a relatively small amount of information from the metering data management system (MDMS). It presents some preliminaries, including a mathematical model and an energy-efficiency function that are to be applied to the uplink transmission power control scheme. The chapter proposes a hierarchical power control scheme for the uplink transmission targeting the real-time data rate reliability and energy efficiency. A two-level Stackelberg game is applied to the proposed scheme, and the Stackelberg equilibrium is derived, based on a linear receiver. The numerical results demonstrated that the proposed scheme can successfully meet data rate reliability requirements while achieving energy efficiency when parameters are adjusted properly. The numerical results also indicated that the proposed Stackelberg game-theoretical approach reaches better energy efficiency as compared with simple noncooperative game approach.
