In this paper, we consider strong domination number of Pnk and Cnk . Let G=(V,E) be a graph, V is a vertex set and E is an edge set of graph G and u,v∈V . u strongly dominates v and v weakly dominates u if (i) uv ∈ E and (ii) d ( u, G ) ≥ d ( v, G ) . A set D⊂V is a strong-dominating set (sd-set) of G if every vertex in V-D is strongly dominated by at least one vertex in D. The strong domination number γs of G is the minimum cardinality of an sd-set.
