Abstract :
A combined performance and dependability (called performability) model for dealing with handoff calls is introduced. Stochastic reward nets (SRNs) are used for this purpose. An SRN model of channel assignment is developed and analyzed. The method of phase type expansion is used is approximate non-exponential call holding time distribution. A discussion, of how hand-off models with failure relate to Markov reward models is also given
