Executive Summary

Power-Controlled Multiple Access (PCMA) is a class of distributed algorithms for Transmitter Power Control (TPC) in wireless networks. In this paper, the authors develop and evaluate a continuous analog (fluid model) of the discrete version of PCMA in order to clearly demonstrate PCMA's capability to, without centralized coordination, induce a network behavior akin to time-division multiple access (TDMA), which they call "induced" TDMA (iTDMA). This analysis allows them to provide new insights into the throughput improvements of PCMA over the classical and widely-used Foschini-Miljanic (FM) constant signal-to-interference algorithm for distributed TPC, particularly in high-interference channels.
