| Popis: | Energy- and spectrum-efficient communication in massive multiple-input multiple-output and multiple-input single-output (MISO)-based heterogeneous network and select the leader small cell using Stackelberg game are proposed in this article. Intersection areas of MISO small cells mobile devices are able to receive the signal from both small cells. Among the small cells, we select the leader small cell using Stackelberg game with two proposed utility functions, for data transmission. We have proposed two algorithms for selecting the leader small cell and frequency allocation between leader and follower small cells in this article. We have analyzed the spectrum of the signal through Vector Signal Generator and Vector Signal Analyzer. The power consumption, SINR and spectral efficiency of the proposed $$\hbox {E}^{2}\hbox {M}^{3}$$ are calculated. Power consumption of the proposed $$\hbox {E}^{2}\hbox {M}^{3}$$ decreases by $${{{\sim}}}\,$$ 30%, SINR and spectral efficiency increases by $${{{\sim }}}\,$$ 20% and $${{{\sim}}}\,$$ 6%, respectively, than existing approaches. |
