Construction of 1- and 2-Connected k-Totally Dominating Set in Disk Graph
In this paper we consider the minimum m-Connected A;Totally Dominating Set (m-k-CTDS) problem in disk graph. We present two centralized approximation algorithms for 1-k-CTDS and 2-k-CTDS problems with approximation ratios 1+In K/2(k-l) + K+K/k and 1+ln K/2(k-l) + K+3K/k, respectively, where K is 5 if k* = rmax/rmin = 1 , otherwise, K = 6(3|log2k*|+2).
