Abstract
A distributed power control technique for wireless networking efficiently balances communication delay against transmitter power on each wireless link. Packets are transmitted over a wireless link from a transmitter to a receiver using a dynamically controlled transmit power level that is periodically updated at the transmitter. The transmit power is computed from i) an observed noise plus interference value of the wireless link and ii) a parameter that determines a balance between per-packet average delay and per-packet average power. In a preferred implementation, the dynamically controlled transmit power level is computed by minimizing the sum of an average delay cost and an average power cost, weighted by the parameter.
