Modeling topologies in Wireless Sensor Networks principally uses domination theory in graphs. Indeed, many dominating structures have been proposed as virtual backbones for wireless networks. In this paper, we study a dominating set that we call Weakly Connected Independent Set (wcis ). Given an undirected connected graph G = (V,E ), we say that an independent set S in G is weakly connected if the spanning subgraph (V, [ S,V \ S ]) is connected, where [ S,V \ S ] is the set of edges having…

The weakly connected independent set polytope in corona and join of graphs
A theorem about complete description of the wcis polytope has been given for 1-sum operation and a class of graphs is also inductively defined from the connected bipartite graphs, the cycles and the strongly chordal graphs, for which the MWWCISP is polynomially solvable.

This paper presents two distributed algorithms for finding a WCDS of G, a weakly-connected dominating set of G if S is dominating and G' is connected, and the graph G' generated by the second algorithm forms a sparse spanner with a topological dilation of 3, and a geometricdilation of 6.
Approximation Algorithms for Connected Dominating Sets
This work considers the more general problem of finding a connected dominating set of a specified subset of vertices and provides a polynomial time algorithm with a (c+1) H(Δ) +c-1 approximation factor, where c is the Steiner approximation ratio for graphs.

Two-Phased Approximation Algorithms for Minimum CDS in Wireless Ad Hoc Networks
It is proved that the approximation ratio of the two-phased algorithm in [10] is at most 7 1/3, improving upon the previous best-known approximation ratio due to [12], and a new two- phased approximation algorithm is proposed and it is proven that its approximation ratio is at least 6 7/18.

This paper presents their own distributed algorithm that outperforms the existing algorithms for minimum CDS and establishes the Ω(nlog n) lower bound on the message complexity of any distributed algorithm for nontrivial CDS, thus message-optimal.
