A greedy approximation algorithm for the minimum (2, 2)-connected dominating set problem
Using a connected dominating set (CDS) to serve as the virtual backbone of a wireless sensor network (WSN) is an effective way to save energy and reduce the impact of broadcasting storms. Since nodes may fail due to accidental damage or energy depletion, it is desirable that the virtual backbone is fault tolerant. This could be modeled as a k-connected, m-fold dominating set ((k,m)-CDS). Given ...
متن کاملSimple Bounds for the Minimum Dominating Trail Set problem
Given a graph G, the Minimum Dominating Trail Set (MDTS) problem consists in ̄nding a minimum cardinality collection of pairwise edge-disjoint trails such that each edge of G has at least one endvertex on some trail. The MDTS problem is NP{hard for general graphs. In this paper lower and upper bounds for the MDTS problem on general graphs are presented.
متن کاملAlgorithms for Minimum m -Connected k -Dominating Set Problem
In wireless sensor networks, virtual backbone has been proposed as the routing infrastructure to alleviate the broadcasting storm problem and perform some other tasks such as area monitoring. Previous work in this area has mainly focused on how to set up a small virtual backbone for high efficiency, which is modelled as the minimum Connected Dominating Set (CDS) problem. In this paper we consid...

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...
