Abstract
We define and study the Minimum Area Spanning Tree (MAST) problem. Given a set P of n points in the plane, find a spanning tree T of P of minimum area, where the area of a spanning tree is the area of the union of the n − 1 disks whose diameters are the edges in T . We prove that the minimum spanning tree of P is a constant-factor approximation for mast. We then apply this result to obtain a constant-factor approximation for the Minimum Area Range Assignment (MARA) problem and for the Minimum Area Connected Disk Graph (MACDG) problem. The former problem is a variant of the power assignment problem in radio networks, and the latter problem is a related natural problem
