Abstract
- We propose a marginal-power-efficiency-based adaptation (MPEA) scheme for distributed power control in wireless communication systems. Nodes autonomously adapt their transmit power by keeping a differential measure of power efficiency, which is defined as the additional capacity obtained per unit of transmit power, at a desirable threshold. We combine the MPEA with the Foschini–Miljanic (FM) algorithm into a power control algorithm for a multihop cellular network where nodes can dynamically adapt to both local and global conditions. We derive a fixed point to which the power allocations converge under the scheme and illustrate a significant improvement in the system throughput. [ABSTRACT FROM AUTHOR]
