Making a Dominating Set of a Graph Connected

open access: yesDiscussiones Mathematicae Graph Theory, 2018
Let G = (V,E) be a graph and S ⊆ V. We say that S is a dominating set of G, if each vertex in V \ S has a neighbor in S. Moreover, we say that S is a connected (respectively, 2-edge connected or 2-connected) dominating set of G if G[S] is connected ...

Minimum Connected Dominating Sets of Random Cubic Graphs [PDF]

open access: bronzeThe Electronic Journal of Combinatorics, 2002
We present a simple heuristic for finding a small connected dominating set of cubic graphs. The average-case performance of this heuristic, which is a randomised greedy algorithm, is analysed on random $n$-vertex cubic graphs using differential equations.

Proper connection number and connected dominating sets [PDF]

open access: greenTheoretical Computer Science, 2015
The proper connection number $pc(G)$ of a connected graph $G$ is defined as the minimum number of colors needed to color its edges, so that every pair of distinct vertices of $G$ is connected by at least one path in $G$ such that no two adjacent edges of the path are colored the same, and such a path is called a proper path. In this paper, we show that

Approximating k-Connected m-Dominating Sets [PDF]

open access: yesAlgorithmica, 2022
A subset $S$ of nodes in a graph $G$ is a $k$-connected $m$-dominating set ($(k,m)$-cds) if the subgraph $G[S]$ induced by $S$ is $k$-connected and every $v \in V \setminus S$ has at least $m$ neighbors in $S$. In the $k$-Connected $m$-Dominating Set ($(k,m)$-CDS) problem the goal is to find a minimum weight $(k,m)$-cds in a node-weighted graph. For $m

Rainbow Connection Number and Connected Dominating Sets [PDF]

open access: yesElectronic Notes in Discrete Mathematics, 2011
AbstractThe rainbow connection number of a connected graph is the minimum number of colors needed to color its edges, so that every pair of its vertices is connected by at least one path in which no two edges are colored the same. In this article we show that for every connected graph on n vertices with minimum degree δ, the rainbow connection number ...

Algorithmic Aspects of Secure Connected Domination in Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2021
Let G = (V, E) be a simple, undirected and connected graph. A connected dominating set S ⊆ V is a secure connected dominating set of G, if for each u ∈ V \ S, there exists v ∈ S such that (u, v) ∈ E and the set (S \ {v}) ∪ {u} is a connected dominating ...

Connected domination value in graphs

open access: yesElectronic Journal of Graph Theory and Applications, 2021
In a connected graph G = (V,E), a set D ⊂ V is a connected dominating set if for every vertex v ∈ V \ D, there exists u ∈ D such that u and v are adjacent, and the subgraph〈D〉induced by D in G is connected.

Energy Efficient Algorithm of Constructing Connected Dominating Set in WSN [PDF]

open access: yesJisuanji gongcheng, 2017
The existing methods of constructing Connected Dominating Set (CDS) have some drawbacks,such as redundant steps,much more energy consumption,and not adapting to the changes of dynamic network topology.So this paper proposes an improved algorithm called ...
