Abstract
A method includes repeatedly transmitting messages from a first wireless node at a transmit power. The method also includes receiving feedback from a second wireless node, where the feedback is based on a quality of reception of at least some of the messages at the second wireless node. The method further includes adjusting the transmit power of the first wireless node based on the feedback to maintain the quality of reception proximate to a setpoint. The feedback could be received from multiple second wireless nodes. The feedback could include quantized values. The quality of reception could include a bit error rate, a packet error rate, and/or a receive signal strength. The quality of reception can be determined for a sliding window associated with a subset of the transmitted messages.
