Quality of Information Maximization in Lifetime-Constrained Wireless Sensor Networks

In this paper, we investigate the quality of information (QoI) maximization problem by jointly optimizing the data rate and transmit power in lifetime-constrained wireless sensor networks. The QoI at the sink node is characterized by the virtue of the network utility, which quantifies the aggregated...
