Hybrid Power Control Algorithms for Streaming and Data Traffic in Wireless Networks

In this paper, we present a new hybrid class of transmitter power control algorithms which couples two separate previous schemes, specifically: (1) the Foschini-Miljanic algorithm for delay-sensitive streaming traffic, and (2) the power controlled multiple access (PCMA) approach for delay-tolerant data traffic. We develop a unified dynamic programming framework to reveal the underlying connection between these two seemingly disparate approaches. We then leverage this framework to design hybrid algorithms exhibiting key performance benefits. Finally, we demonstrate through simulations substantial performance gains over the traditional approaches, that is, lower power consumption and higher throughput.
