Connected dominated subsets (CDS) of nodes in wireless sensor network are always selected to form a virtual backbone. Construction of r-hop 2-connected dominating sets can reduce the size of CDS and the total amount of information to be transmitted. The 2-connected properties can provide higher fault tolerance and robustness as well. In this paper an approximation r-hop 2-connected dominating set...
Connected dominated subsets (CDS) of nodes in wireless sensor network are always selected to form a virtual backbone. Construction of r-hop connected k-dominating sets ((k, r)-CDS) can reduce the size of CDS and the total amount of information to be transmitted. Their multiple dominating properties can provide higher fault tolerance and robustness as well. In this paper a (k, r)-CDS construction approximation...
