Approximation 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 کاملConstructing Minimum Connected Dominating Set: Algorithmic approach
Connected Dominating Set is popularly used for constructing virtual backbones for broadcasting operation in WSNs. UD Graph is the most suitable model for a wireless sensor network. In this paper we provide an algorithm to find MCDS in UD Graph. It is based on the computation of convex hulls of sensor nodes or vertices. Constructing a virtual backbone in WSNs is an important issue because it red...
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 کاملModified Minimum Connected Dominating Set formation for Wireless Adhoc Networks
Nodes of minimum connected dominating set (MCDS) form a virtual backbone in a wireless adhoc network. In this paper, a modified approach is presented to determine MCDS of an underlying graph of a Wireless Adhoc network. Simulation results for a variety of graphs indicate that the approach is efficient in determining the MCDS as compared to other existing techniques.
