Analysis of Multi-Server Priority Queueing System with Hysteresis Strategy of Server Reservation and Retrials

A multi-server queueing system with two types of requests and preemptive priority one type is considered as a model cell cognitive radio under practical suggestions about the arrival flows. hysteresis strategy for server reservation suggested to mitigate effect interruption service low requests. Under arbitrarily fixed values sets thresholds defining this strategy, behavior described by level-dependent multi-dimensional Markov chain. Formulas computation performance characteristics are derived. Numerical examples illustrating dependence main on control numerical solution problem optimal choice reported.
