Stochastic Power Control for Wireless Systems: Centralized Dynamic Solutions and Aspects of Decentralized Control
نویسندگان
چکیده
This paper considers power control for log-normal fading channels. A rate based power set point control model and associated performance measures are introduced. The value function of the stochastic optimal control is a viscosity solution to the associated HJB equation and is approximated by smooth functions. Finally, by introducing multi-objective indices, we give a game theoretic formulation to the dynamic power optimization problem.

متن کاملThe Common Information Approach to Decentralized Stochastic Control
Many modern technological systems, such as cyber-physical systems, communication, transportation and social networks, smart grids, sensing and surveillance systems are informationally decentralized. A key feature of informationally decentralized systems is that decisions are made by multiple decision makers that have access to different information. This feature violates the fundamental assumpt...
