Dominating Sets and Connected Dominating Sets in Dynamic Graphs [PDF]

open access: yes, 2019
In this paper we study the dynamic versions of two basic graph problems: Minimum Dominating Set and its variant Minimum Connected Dominating Set. For those two problems, we present algorithms that maintain a solution under edge insertions and edge deletions in time $O( \cdot \text{polylog}~n)$ per update, where $ $ is the maximum vertex degree in the

Enumerating Connected Dominating Sets

open access: yes, 2022
The question to enumerate all inclusion-minimal connected dominating sets in a graph of order $n$ in time significantly less than $2^n$ is an open question that was asked in many places. We answer this question affirmatively, by providing an enumeration algorithm that runs in time $\mathcal{O}(1.9896^n)$, using polynomial space only.

Perfect Outer-connected Domination in the Join and Corona of Graphs

open access: yesRecoletos Multidisciplinary Research Journal, 2016
Let ๐บ be a connected simple graph. A dominating set ๐‘† โІ ๐‘‰(๐บ) is called a perfect dominating set of ๐บ if each ๐‘ข โˆˆ ๐‘‰ ๐บ โˆ– ๐‘† is dominated by exactly one element of ๐‘†.

Inverse Domination Parameters of Jump Graph

open access: yesRatio Mathematica, 2023
Let G=(V,E)\ be a connected graph. Let D be a minimum dominating set in G.\ If V-D contains a dominating set D^\prime of G, then D^\prime is called an inverse dominating set with respect to D.

Below all subsets for Minimal Connected Dominating Set [PDF]

open access: greenSIAM Journal on Discrete Mathematics, 2016
A vertex subset $S$ in a graph $G$ is a dominating set if every vertex not contained in $S$ has a neighbor in $S$. A dominating set $S$ is a connected dominating set if the subgraph $G[S]$ induced by $S$ is connected. A connected dominating set $S$ is a minimal connected dominating set if no proper subset of $S$ is also a connected dominating set.

Connected Dominating Sets [PDF]

open access: yes, 2009
Wireless sensor networks (WSNs) are now widely used in many applications. However, routing in WSNs is very challenging due to the inherent characteristics that distinguish these networks from other wireless networks. The concept of hierarchical routing is widely used to perform energy-efficient routing in WSNs.

Algorithmic complexity of secure connected domination in graphs

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
Let be a simple, undirected, and connected graph. A connected (total) dominating set is a secure connected (total) dominating set of G, if for each there exists such that and is a connected (total) dominating set of G. The minimum cardinality of a secure

Connected Dominating Sets in Triangulations

open access: yes, 2023
We show that every $n$-vertex triangulation has a connected dominating set of size at most $10n/21$. Equivalently, every $n$ vertex triangulation has a spanning tree with at least $11n/21$ leaves. Prior to the current work, the best known bounds were $n/2$, which follows from work of Albertson, Berman, Hutchinson, and Thomassen (J. Graph Theory \textbf{
