An Exact Algorithm for Connected Red-Blue Dominating Set
In the Connected Red-Blue Dominating Set problem we are given a graph G whose vertex set is partitioned into two parts R and B (red and blue vertices), and we are asked to find a connected subgraph induced by a subset S of B such that each red vertex of G is adjacent to some vertex in S. The problem can be solved in O(2) time by reduction to the Weighted Steiner Tree problem. Combining exhausti...
متن کاملTotal dominating set based algorithm for connected dominating set in Ad hoc wireless networks
In an efficient design of routing protocols in ad hoc wireless networks, the connected dominating set (CDS) is widely used as a virtual backbone. To construct the CDS with its size as minimum, many heuristic, meta-heuristic, greedy, approximation and distributed algorithmic approaches have been proposed in the recent years. These approaches mostly concentrated on deriving independent set and th...
متن کاملApproximation Algorithm for Minimum Weight Connected m-Fold Dominating Set
Using connected dominating set (CDS) to serve as a virtual backbone in a wireless networks can save energy and reduce interference. Since nodes may fail due to accidental damage or energy depletion, it is desirable that the virtual backbone has some fault-tolerance. A k-connected m-fold dominating set ((k,m)-CDS) of a graph G is a node set D such that every node in V \ D has at least m neighbor...
متن کاملA Refined Exact Algorithm for Edge Dominating Set
We present an O∗(1.3160n)-time algorithm for the edge dominating set problem in an n-vertex graph, which improves previous exact algorithms for this problem. The algorithm is analyzed by using the “Measure and Conquer method.” We design new branching rules based on conceptually simple local structures, called “clique-producing vertices/cycles,” which significantly simplify the algorithm and its...
متن کاملOn connected dominating set games †
Many authors studied cooperative games that arise from variants of dominating set games on graphs. In wireless networks, the connected dominating set is used to reduce routing table size and communication cost. In this paper, we introduce a connected dominating set game to model the cost allocation problem arising from a connected dominating set on a given graph and study its core. In addition,...
