Energy-Aware Competitive Power Allocation for Heterogeneous Networks Under QoS Constraints
Giacomo Bacci, E. Veronica Belmega, Panayotis Mertikopoulos +1
This work proposes a distributed power allocation scheme for maximizing energy efficiency in the uplink of orthogonal frequency-division multiple access (OFDMA)-based heterogeneous…
