TL;DR

This paper develops distributed power control strategies for multiple access channels using stochastic game theory, enabling energy-efficient communication with limited system knowledge.

Contribution

It introduces a stochastic game framework for distributed power control, characterizes the utility equilibrium region, and proposes an explicit power control strategy based on time-sharing.

Findings

Achievable utility equilibrium region characterized.

Explicit power control strategy proposed.

Distributed control requires only partial system knowledge.

Abstract

Transmitters of a multiple access channel are assumed to freely choose their power control strategy in order to be energy-efficient. We show that in a stochastic game framework, we can develop energy-efficient distributed control strategies which only require partial knowledge of the entire system. Achievable utility equilibrium region is characterized and based on time-sharing, an explicit power control strategy is proposed.
