Let G be a graph. An injective map is called a pair sum labeling if the induced edge function, defined by is one-one and is either of the form or according as q is even or odd. A graph with a pair sum labeling is called a pair sum graph. In this paper we investigate the pair sum labeling behavior of subdivision of some standard graphs.
