  • Abstract
    Engset´s model of resource blocking with a finite population has recently been generalized to allow blocked users to have a recovery time before they re-enter contention for the resources. We propose an algorithm to find the stationary distribution of the resulting level-dependent quasi-birth-and-death (LDQBD) process, and hence the blocking probability. Its running time is linear in the number of resources and the population size.
