Abstract--The paper introduces DILOC, a distributed, iterative algorithm to locate sensors (with unknown locations) in 1, with respect to a minimal number of + 1 anchors with known locations. The sensors and anchors, nodes in the network, exchange data with their neighbors only; no centralized data processing or communication occurs, nor is there a centralized fusion center to compute the sensors' locations. DILOC uses the barycentric coordinates of a node with respect to its neighbors; these coordinates are computed using the Cayley
