An Optimal Algorithm to Find Minimum K-hop Dominating Set Sukumar Mondal

Domination in graphs has been an extensively researched branch of graph theory. Among the variations of dominations, k-hop domination has been brie?y discussed in the past and it has important applications in communication networks. In this book, we consider the problem of ?nding a minimum k-hop dominating set of interval graphs. For this purpose, we ?rst construct the BFS-tree T with root as 1. After then we identify the main path of the BFS-tree T. Next we ?nd the ?rst member of k-hop dominating set of interval graph, by using some results. Then we ?nd the next member of k-hop dominating set by a procedure FindNext. Here, we proposed an O(n) time algorithm to ?nd a minimum k-hop dominating set of undirected and connected interval graphs with n vertices
