Weakly connected domination critical graphs [PDF]

open access: yesOpuscula Mathematica, 2008
A dominating set \(D \subset V(G)\) is a weakly connected dominating set in \(G\) if the subgraph \(G[D]_w = (N_{G}[D],E_w)\) weakly induced by \(D\) is connected, where \(E_w\) is the set of all edges with at least one vertex in \(D\).

Strongly connected dominating set construction algorithm balancing time delay and energy consumption

open access: yesTongxin xuebao, 2012
To the asymmetry of link in wireless sensor networks,a problem about the strongly connected dominating tree with bounded transmission delay (SDTT) was put forward.The distributed strongly connected dominating tree (SCDT) algorithm was also proposed to ...

Disjoint Secure Domination in the Join of Graphs

open access: yesRecoletos Multidisciplinary Research Journal, 2016
Let G = (V(G),E(G)) be a simple connected graph. A dominating set S in G is called a secure dominating set in G if for every u ∈ V (G) \ S, there exists v ∈ S ∩ NG(u) such that (S \ {v}) ∪ {u} is a dominating set.

Rainbow connection number, bridges and radius [PDF]

open access: yes, 2011
Let $G$ be a connected graph. The notion \emph{the rainbow connection number $rc(G)$} of a graph $G$ was introduced recently by Chartrand et al. Basavaraju et al.

Domination Parameters of a Graph and its Complement

open access: yesDiscussiones Mathematicae Graph Theory, 2018
A dominating set in a graph G is a set S of vertices such that every vertex in V (G) \ S is adjacent to at least one vertex in S, and the domination number of G is the minimum cardinality of a dominating set of G.

Characterization of Upper Detour Monophonic Domination Number

open access: yesCubo, 2020
This paper introduces the concept of \textit{upper detour monophonic domination number} of a graph. For a connected graph $G$ with vertex set $V(G)$, a set $M\subseteq V(G)$ is called minimal detour monophonic dominating set, if no proper subset of $M ...

On the number of outer connected dominating sets of graphs

open access: yes, 2012
Let $G=(V,E)$ be a simple graph. A set $S\subseteq V(G)$ is called an outer-connected dominating set (or ocd-set) of $G$, if $S$ is a dominating set of $G$ and either $S=V(G)$ or $V\backslash S$ is a connected graph.

A Greedy Algorithm on Constructing the Minimum Connected Dominating Set in Wireless Network

open access: yesInternational Journal of Distributed Sensor Networks, 2016
In the past 20 years, the connected dominating set (CDS) as a virtual backbone network has been widely used in the wireless networks. Many researchers have been devoted to designing approximate algorithms for CDS problem since constructing the minimum ...

Connected Partitions via Connected Dominating Sets

open access: yes
The classical theorem due to Győri and Lovász states that any $k$-connected graph $G$ admits a partition into $k$ connected subgraphs, where each subgraph has a prescribed size and contains a prescribed vertex, as long as the total size of target subgraphs is equal to the size of $G$.
