Total Edge Irregularity Strength of Hexagonal Networks

Given a graph \( G = (V, E) \), a labeling \( \partial: V \cup E \to \{1, 2, \dots, k\} \) is called an edge irregular total \( k \)-labeling if for every pair of distinct edges \( uv \) and \( xy \), \( \partial(u) + \partial(uv) + \partial(v) \neq \partial(x) + \partial(xy) + \partial(y) \). The minimum \( k \) for which \( G \) has an edge irregular total \( k \)-labeling is called the total edge irregularity strength of \( G \). In this paper, we examine the hexagonal network, which is a well-known interconnection network, and obtain its total edge irregularity strength.
