Game Theory Power Control Algorithm

With the substantial growth in the cellular mobile communication market, the next generation of communication systems will transition to mobile multimedia communication. This evolution means that communication will no longer be limited to voice sources but will extend to multimedia sources. This shift raises an interesting challenge: how to implement power control for multimedia sources beyond traditional voice transmission. To explore this issue, we introduce mathematical models and concepts from microeconomics, combined with game theory, to enhance our understanding of the problem. In this paper, we examine call quality, referred to as "utility," and model distributed power control in CDMA telephone communications as a non-cooperative game. This approach often involves algorithms where each transmitter independently adjusts its power level based on local utility maximization, typically implemented through iterative update rules in code. By conducting an in-depth analysis of this problem and the corresponding model, we can better comprehend developments and trends in this field, providing valuable insights and references for the future advancement of mobile communication technologies.
