This work addresses the challenges of power control in dense heterogeneous IoT uplink scenarios, where conventional methods struggle due to incomplete channel state information, inter-device interference, and stringent size, weight, and power (SWaP) constraints. To overcome these limitations, the authors propose a novel epistemic Bayesian game-theoretic framework that, for the first time, incorporates cognitive hierarchy modeling into power control. The approach employs a two-layer belief structure to capture users’ reasoning about opponents’ strategies and their own strategic self-assessment. Spatial randomness is modeled using Poisson point processes and stochastic geometry, while decentralized power optimization is achieved without feedback by leveraging Jensen–Shannon divergence analysis. Theoretical derivations yield a coverage probability-based utility function, and simulations demonstrate that, under high network density and stringent SINR requirements, the proposed method significantly reduces transmit power compared to fractional power control (FPC) and signal-to-noise-and-channel-power control (SNCPC), while maintaining the target coverage probability.
