Abstract
Spatially distributed measurements have been used for hundreds of years to perform geolocation, geodesy and triangulation. In WW1 acoustic sensor arrays were used to locate the direction of cannon fire based on correlation between sensor readings. Sensors in the Internet-of-Things (IoT) auto-locate their nodes based on correlation between received pilot signals. In genomics influential nodes are located in transcriptional or lineage networks based on correlation between omic profiles. Whether the node is a target, a sensor, or a nucleotide sequence, the problem of node localization is of central interest in many disciplines of science and technology. In this talk I will provide perspectives on the general node localization problem, discuss solutions and algorithms, and address future opportunities and challenges.
