Distributed reverse-link power controls in wireless networks: Performance risk aversion and person-by-person equilibrium

摘要

This paper highlights the challenges of distributed reverse-link power controls under signal-to-interference-plus-noise ratio constraints. A class of wireless networks considered here is consisted of multiple sources, multiple relays, and a single destination. Power measurement reports are subject to quantization errors, observation noises, and transport delays in the forward links. In effect, the search for a minimal tuple of distributed power command policies, which ensure optimal mean-risk aware performance indices, is restricted to a person-by-person equilibrium. Towards closed-loop performance reliability, self-directed user terminals are capable of incorporating risk-averse attitudes in transmit power allocations in accordance of near-far field issues and multi-access interferences.
