The topological structure of interconnection networks represented by graphs has been used extensively. These structures are currently being used for many applications, ranging from internal buses in very large-scale integration (VLSI) circuits to wide region PC systems. Labeling is one of the most interesting fields with a wide variety of applications in graph theory. In this paper, we investigate signed cordial labeling and signed product cordial labeling of some interconnection networks.
