Game theoretic model for power optimization in next-generation heterogeneous network

In this game theoretic proposed work, non-cooperative game is considered in heterogeneous network (Hetnet), and each base station is treated as a competitive player in the game, where all base station compete selfishly to transmit at higher power. The solution of this game theoretic approach is mathematically derived to find out the optimal point through Nash equilibrium (NE). It leads to enhancing the overall performance in terms of throughput, energy efficiency and power consumption, through the vicinity of constraints such as load, small cell density and unnecessary blockage. The reward function is designed to provide each player with the desired transmission power by taking into account their power consumption, base station density and the risk of blockage. For the proposed approach, the existence of the Nash equilibrium is proved, and a next-generation heterogeneous network is suggested with an optimal cost solution.
