Abstract

Communication networks can be represented as graphs, where vertices represent
network nodes and edges represent connections between them. Various graph
theory parameters, such as connectivity, toughness, tenacity, binding number,
scattering number, and integrity, were presented to assess the vulnerability of
networks. Calculating the values of these vulnerability parameters can be challenging,
particularly for certain classes of graphs, such as generalized Petersen
graphs, due to their diverse structures. This paper establishes upper and lower
bounds for the tenacity of generalized Petersen graphs. We demonstrate a lower
bound of 1 for the tenacity, T (GPG(n, k)), across all values of n and k. Additionally,
we explore the tenacity values of generalized Petersen graphs and present
a general upper bound for the tenacity value in this graph type. By using the
relationship between the tenacity parameter and the connectivity (κ) and toughness
(t) parameters, we also update some theorems related to the connectivity
and toughness of generalized Petersen graphs.
