On The Average Lower Independence Number of Some Graphs
Abstract
In a communication network, several vulnerability measures areused to determine the resistance of the network to disruption of operation after the failure of certain stations or communication links. If the communication network is modeled as a simple, undirected, connected and unweighted graph G, then average lower independence number of a graph G can be considered
as a measure of graph vulnerability and is dened by
iav (G) = 1 jV (G)j Σ v2V (G) iv(G)
where iv(G) is the minimum cardinality of a maximal independent set that contains v. In this paper, I consider the average lower independence number of the thorn graphs of special graphs.
