Abstract

Transmitter energy is a valuable resource in wireless networks. Transmitter power management can have an impact on battery life for mobile users, link level QoS and network capacity. We consider efficient use of transmitter energy in a streaming application.. We formulate an optimization problem that corresponds to minimising the transmission energy required to achieve an acceptable level of distortion subject to a delay constraint. By considering jointly the selection of coding parameters and transmitter power, we can formulate an optimal policy. We present results illustrating the advantages of jointly considering these two variables.
