Research ArticleOpen accessAll words, across the recordCONSTRUCTION OF STRATEGIC CONNECTED DOMINATING SET FOR MOBILE AD HOC NETWORKSVictor Ceronmani Sharmila, Amalanathan GeorgeConnected Dominating Sets (CDSs) can serve as virtual backbones for wireless networks. A smaller virtual backbone (minimum size CDS) incurs less communication overhead. Unfortunately, computing a minimum size CDS is NP-hard and thus many algorithms were developed which concentrates on how to construct smaller CDSs. Aiming for minimum number of nodes in CDS, results in CDSs that are highly unstable. … …Journal of Computer Science, Vol. 10, Issue 2 · 16 Nov 2013 · 6,913 accessesView PDFCite
