We propose and compare three channel recovery schemes for fixed channel assignment. In Scheme I, a failed channel is switched by an idle channel whenever it is available. In Scheme II, the switching strategy is employed only after an attempt to restore the failed channel within a short period of time is unsuccessful. Scheme III is a hybrid of Schemes I and II: for some of the failed channels, Scheme I is applied; for the others, Scheme II is used. To reflect the traffic pattern in a realistic way, a fixed point iteration scheme is applied to capture the dynamic behavior of the handoff arrivals. Stochastic reward nets (SRNs) are developed for the performability analysis of the three schemes.
