Abstract

In this paper, we discuss dynamic binary transmit power control strategies for a mobile data user, taking into consideration channel dynamics, residual battery energy and communication delay constraints. We define a utility function for the mobile that takes into account communication throughput, energy consumption as well as delay. A dynamic programming algorithm is employed to maximize the user's utility, by which we obtain optimal transmission policies for different scenarios. The resulting transmitter power policies can be implemented using signal strength measurements and knowledge of residual battery energy.
